I have a Dodge Dakota that I disconnected the heater core over a year ago because it started leaking down the fire wall both inside and out. To replace the core you have to pull the dash out completely to get to the core. The estimate was $500 to $600. I got the truck up to temperature, reconnected the hoses and put in 8 oz. of K-Seal. With in 10 minutes it stopped leaking and I have heat and saved $490 dollars. (John Thompson – Pennsylvania USA)

The local mechanic “John Shaft”, wanted to charge me $1200 for a new water pump. My friend showed me some other brands. But I was willing to pay $40 for a bottle if it was going to work. Thanks to Pep Boys, the guy told me exactly where I could find it. It was much less than $40 and I even bought a bottle of 50/50. I had to drive around the corner to the shopping center to get it to the temperature. Went inside a few store and drove it hard on a small stretch of highway then into my development. The gauge was steady at the normal temperature. Then took it 15 miles to see my mom. NO PROBLEM. Drove back, still no problem.
IT WORKS!!! Steven Hill – Delaware USA.

This is a follow up review of the K seal coolant leak repair it’s been 7 months since we first put this product into a vehicle its a 2002 Honda CRV ex with 146,000+ miles on it. 7 months ago, we were on the verge of trashing this vehicle and we saw a advertisement for K seal on TV and decided to give it a try , knowing that had nothing to lose. Well, we have not been disappointed!

Blog website posting on a coolant leak thread discussing the issues with a leaking heater matrix:
28 November 2015
“I was about to spend several hundred dollars due to steam from tailpipe and loss of water. I wasn’t getting water in crankcase but into cylinder. I decided to search for a product that might solve the problem. Found your video on U-Tube and today I purchased K-seal and followed instructions, ran vehicle for 30 minutes and presto—no more steam. Started engine after three hours and got very small amount of steam for 10 seconds, then none. Thanks for saving my hard earned money!” Jerry Phillips (Texas USA)

“Yep, K Seal is a great long term fix for small or emerging leaks on your heater Matrix. Just add to the expansion tank. Mine started leaking a couple of years ago. K Seal sorted it immediately and it’s been fine since (20,000 miles)”

Dear all at k seal…your awesome product saved me a lot of cash ..I went for a quote for a new matrix and my heart skipped a beat upon the answer…and then a mechanic suggested k seal…I laughed because I’d already used Radweld im my 30 year old car..But k seal actually worked I now have heating in my car and dry mats…many thanks.

We have 30 different products on our shelf that claim to fix leaks.
Me and my staff grab K-SEAL over any product when a garage calls or someone walks in asking if we have a coolant stop leak.
Thank you for making a great product that we can stand behind with confidence!

“My 2004 Freelander 1 KV6 had overheating issues. The coolant started bubbling after only a 15 minute drive. LR garage quoted £1700 to fix it. I was advised to try K-Seal. It didn’t work immediately but after a few days the problem was completely gone! No more overheating at all. Very impressed!” Paul Buck UK.

“This vehicle had a slight head gasket leak. When I started the SUV to add K-Seal to seal it up, the compression on the bad cylinder with coolant was too much and caused a rod knock to start. I ran the engine for 30 minutes, and the head gasket seems to have sealed – no more white smoke or coolant smell.” UsedCarsSearch.net USA

I emailed your company in 2012 about how K-Seal fixed my radiator and how happy I was with your product. Here is my original email……. 10/16/2012: “Just wanted to let you guys know that I am always very skeptical about anything I put in my engine let alone anything I see on the internet.
But paying $400.00 for a new radiator just was not going to work for me. I own a 2002 Toyota 4 Runner, I have had it a very long time and noticed last year that engine was getting hot all the time and radiator fluid was leaking. Took it to the shop and they told me I needed a new radiator, I flipped at the cost.
That’s when I hit the auto stores and the internet. I found K-seal website from all the great testimonials and reviews of the product. Just have to say, after I used it, the engine never got hot again, and antifreeze levels were stabilized. I have been worry free from an overheated engine for the past 12 months. I saved a ton a money !!!! Thanks K-seal !!!!” Tim Mayersky, USA.
Well, just wanted to let you folks know that I am still driving my 4-Runner and couldn’t be happier with my fixed radiator, still in perfect condition thanks to your product ! Its been 33 months since I first poured that little bottle of magic into my radiator to fix my leak and overheating, and still going strong with no issues. I still cant believe it. Thanks K-Seal !!

I used k seal on my Honda Accord 92 lx wagon and this stuff worked beautifully I had jus blown the head gasket when I was installing the radiator fans in and I was devastated..but k seal honestly saved me almost 1500$ and I’m jus thankful you guys are great thanks. Daron Williams (USA) Via Facebook

I found out the problem and this stuff is freaking amazing “so far” my car stop running hot and it’s running amazing right now I would definitely recommend this stuff..k-seal literally is saving me 1450$ Daron Williams (USA)

Hi Thanks to Colin I have had great success with your product. I had water to oil problem with water like a milk shake. I tried the product by taking the plug out of the faulty cylinder plus unplugged the injector and making sure this eliminated all the back pressure in the header tank. I ran the engine with the header tank lid off and had a little success so i then ran the car with the lid on after 30 mins I replaced the plug the car has now run for 1 hr with no bubbles. slight very slight white smoke but this will be the water in the oil burning off. great product would recommend the product and Colin (tech) to anyone.

Bought this today for my coolant leak .. its fixed already .. worked like awesoness! (Denise – Facebook)
25 February 2015
First let me say how totally amazed and satisfied I am K-Seal. I had to purchase a used car that would use far less gas than my truck for commuting to work. I found a 2003 Civic with 150K miles on it. After a month, she began running hot and soon was in desperate need of repair. It was indeed a head gasket leak but the cost of repair was half the value of the car.
My mechanic suggested K-Seal as an alternative. Needless to say, after using the K-Seal, the car has been running at a perfect temp. Thanks again for a great product. Kyron (USA)
20 February 2015
Had did I say” had “a water pump leak and used your product. All I can say is thank-you a million times.as the leak is no more.I have used other products and was skeptical with yours. Your product saved me hundreds. I saved the empty container to show everyone about your product . THANK-YOU AGAIN
12 February 2015
Absolute genius. Catch the leak small, and plug it with K-Seal. When the cost of the head gasket repair exceeds the value of the car, use this. (YouTube Comment)

Hello every one my name is Rick ,I have worked in autozone for about 6 years and always have herd good things about k seal! Recently my dodge neon overheated and I gotta say it! K seal to the rescue.

I’d just like to say that my old Mazda 626 finally developed a coolant leak at the head gasket to the external face. 10 minutes after K-Seal the leak has gone entirely. Thanks! Jon (Australia)
29 January 2015
I had a bad coolant leak and sent my car off to the mechanic to have it checked out. I was told it would be close to $1000 for the repair. I didn’t have the money to have it fixed and did a google search. I found out about K-Seal and did a little checking out of your product and found it on sale at a local auto parts. So what did I have to loose, right. I followed your instructions and was surprised on just how quickly it worked. The way I see it is your product saved me $1000 in repairs. Thank you for making such a great product. I shared my use of it on Facebook with all my friends. My God please keep up the good work. Thank you and everyone who works for you. I used it on 01/27/14. William (USA)

I bought the product monday and used tuesday morning. Drove about 110 miles yesterday with no problems. Looked today and the wet spot at the top seam of my radiator was dry. Thanks for having a product that actually works. The shop wanted almost $1000 to replace radiator…saved that money. Steve Boles (USA)

We are nowfully converted to k-Seal for cooling system repairs because we had a holiday maker come in last summer with a leaking radiator. He was a German, at the end of his holiday and just about to head off to the ferry home, I tried to source a new rad for his motorhome but the best I could get was a two day wait, as Forte stockists we added our Forte cooling system stop leak, the leak stopped but after ten minutes running in the shop it started again. I had heard of K-Seal but never tried it, I thought the brag of it being a permenant repair was a tad far fetched but we had to try to get him to the ferry at least. I called my factor and they sent me the little blue bottle out on the next van, while we were waiting we drained and flushed the offending cooling system just in case cross contamination might cause a problem. When the K-Seal arrived we added it to the system and ran up the engine the leak stopped almost immediately, we let it run for a further hour with no sign of the leak recurring, I explained to the customer that he should keep a close eye on his temp guage and check his coolant level at every stop, he was carring plenty of water and I saw no reason why he should not make it to the ferry at least.
About a week later I got a call from him, he had made the ferry with no problems and no coolant loss, in fact he got all the way back home, he assured me he was going to get the rad done soon.
Then two weeks ago a german motorhome turned up on our forcourt as the driver walked toward the garage he looked familier but I could’nt place him right off, then as he walked toward me it dawned on me, He asked me if I could please take a look at his engine and I followed him out he opened the bonnet and showed me his radiator, still the same rad as we repaied with K-Seal.
we have been using K-Seal since that first time we used it and it now sits on the shelf where the Forte used to sit. Well done Kalimex, a great product that really does do what it promises. Len Beresford Trencrom Garage Ltd.

“1999 ford Taurus, 3.0 DOHC 316859 Original miles never been worked on other than regular maintenance. My radiator was about 50% capacity and with 105 degree heat outside my car over heated .Turn on the heater to cool the motor down that worked but the damage to the head gasket started. Within a month the gave up.
I parked my car a rented a car thinking my Taurus was done, I was pointed to the Web and saw head gasket parts and the results for parts houses everywhere and liquid head gasket repair. I did more research between your product and blue devil. Then went O’Reillys saw both products $60.00 and $15.00 my budget was tight saw I bought k-seal, and a new radiator. With exhaust coming through the coolant reservoir bubbling up I poured the K-Seal in and in 4 minutes no more exhaust in the coolant. I flushed the system and put another treatment in and antifreeze, now 2000 miles later still running well . Thank you for your technology.
Regards, Tony” USA.

Just wanted to thank you for a great product. Our 1924 Studebaker (non-pressurized cooling system) had a small leak in the block that I was unable to seal with metal epoxy. After finding out about K-Seal from a mechanic I decided to try it. I mixed up the 8 oz bottle with a gallon of water and poured it into the radiator with the engine running. By the time I placed that bottle on the ground, picked up another gallon of plain water and started pouring it in, the leak had stopped! The next day we took the Studebaker on a 90 mile trip to and from a car show and it didn’t leak a drop of water. Dave Burden USA

I’m writing to say ThankYou for saving my 1963 chevy show truck’s engine. It had a crack in the water jacket on the outside of the block, and after using your product,it no longer leaks.I check it every time I go to cruise nights or shows thinking it’s going to leak, but it’s holding strong. I’m very impressed. Dave Cox USA

K-Seal erased my skepticism regarding remedies in a bottle.
K-Seal stopped a small leak in the right cylinder head of my low mileage 1994 Nissan Pathfinder. The leak was caused by overzealous drilling while trying to remove a broken exhaust stud.
I had gotten quotes upward of $2000 to replace the right head as well as the left one.
I followed the simple instructions and poured K-Seal directly in the radiator. I let the engine idle for 20 minutes. No more leak!

Wow !!! My Audi A4 had a possible water pump leak. It was pouring all my anti freeze onto the ground, I was so angry because I had just spent $600 getting CV joints done and did not want to spend $1400 getting water pump timing belt ect… replaced yet. I found you guys on the internet went to my local auto zone, shook that baby up and dumped it into my overflow tank. The leaking stopped almost imediatley! You guys just saved me from having to spend another $1400 thank you so much ! You’ve made my whole day possibly week or even month and my wallet and bank account thank you from the bottom of their hearts.

Have had my ’02 for just short of a year. Have added tires, step nerf bars, a new headliner and heat seats. It’s a 4.7L. Had a head gasket leak on #5, but lucked out when a bottle of K-Seal fixed it. Whew! Had a new purple ’98 R/T a couple of vehicles back (’05 Magnum R/T in between). Love these Dodges. This pic still has the old Firestones. It has MT Bajas on it now. Bill Conkel USA

I called your advice team before using K seal on my heater matrix leaking problems and against the advice of a Landrover specialist I decided to give it a go…to be frank I had visions of the pipes blocking up and other possibly even worse senario’s,but not having the required amount of cash available went for it.
I have to say it seems to have done an excellent job,no more smell or smeared interior windscreen…and over 350.00 better off lets hope it lasts !
Many thanks for online advice realy glad I took it ! Richard Chadwick
24 April 2014
it worked for me!!! i wouldn’t believe it if i hadn’t seen it with my own eyes, my car was shooting water out of the back side of the engine, either blown head gasket or warped head.and it sealed that up….i dont know how long it will hold but i let the vehicle run on idle for an hr and no more leaks or burning antifreeze.

Used on 602diesel, suspected head gasket failure, high coolant temp, cold air in heating matrix, air in expansion box, coolant being expelled due to pressure. Used large bottle after1/2 hour bubbles and excess pressure in expansion box had ceased, engine temp had stabilized.
An excellent product would have no hestation in recommending this to anyone !! Craig Sifleet (email)

Hello, My Mk4 Golf TDi has been driving me mad for a few weeks with steaming up windows, even on very long runs, with or without air-con on and at all heater settings. Initially I thought it was greasy glass coupled with a leak from a door or vent seal but an increasing smell and fogging up in any climate, together with in depth internet searching led me to suspect heater matrix failure – despite no internal leak. I tried K seal today and within a 20 mile drive with the heat on max part of the time the fogging has gone. I am very pleased as I can see out of the windows, there is no eye stinging fogging and I have hopefully avoided the cost and nuisance of heater matrix replacement. I just wanted to say this is a very good product. Pat Graham (UK)

I have used your K-Seal product and it worked wonders on my C180 water going to oil. I did head gasket twice but leak did not stop, but with one bottle it all stopped. Thank you for this product.
5 March 2014
I Highly Recommend K-Seal! After my engine started running hot and running rough I noticed a burning coolant smell coming from my Ford Explorer and a little puddle of coolant sludge on my driveway so I took it into Firestone to have it looked at. They told me I had a leak in the thermostat housing, but worse the engine failed a pressure test and that my block was cracked and I needed a new motor for $5400. Well, since the Explorer was on it’s way to becoming a huge paper weight I decided to try K-Seal. It’s only been 2 days since I used the stuff but so far the car is running nearly perfect (idling normal, etc), not overheating at all, no more burning coolant smell or coolant sludge on my driveway. K-Seal worked great for me and hopefully it will hold up for a while. Keeping my fingers crossed. YouTube Comment

Hi I used your product 6 months ago to try and stop my Vauxhall Calibra V6 from using so much coolant. It was suspected to be a head gasket problem, as you can imagine on a v6 engine this would have been a costly repair job. I decided to give your product a try and it has worked perfectly. I would just like to say thank you and keep up the good work your product is amazing. Rob.

I had a bad leak in the radiator system of my ’02 Chev. Impala. I had to refill the over flow tank numerous times i.e. 1 gallon per month. I chose to do something on my own before taking it to the dealer for repair. I purchased an 8 oz. container of K-Seal from O’Reilly Auto Parts, Nashville, Tn. and poured it in the over flow tank and prayed it would work. 1/13/14 to 1/23/14 and it hasn’t leaked a drop. Amazing stuff dont you think? Maitland Gunderson USAF Retired

“I had a head gasket leak that was pretty bad. I drove to the auto parts store in my area, and by the time I got there the car was already over heated. I went to the store and saw your product k seal; I wasn’t sure at first I was going to work but I said hey why not give it a try. I left the car cool down and after about 30 minutes I added the K seal to the radiator with in about 1 minute the leak completely stopped. I had already remove the thermostat 2 weeks ago because of a head gasket failure and tried another product that cost way more then what your product cost and less effective. this k seal stuff truly is amazing I would recommend this to all my friends and family and I just want to thank you guys for having such a great product.
The car I’m driving is an 8 cylinder Jeep Cherokee 96 I cannot say more than enough good things about this product; I literally only had a few dollars left to my name and you guys really help me out. I will continue to the product in the future and once again thank you and much love from Edison New Jersey Gregory Kaloyerakis”

“A small garage used K-Seal Permanent to seal a leaking radiator in my Toyota Carina. To my surprise it has worked for two years +” Michael Boylan (Spain)
17 November 2013
I own a 1997 GMC 1/2 ton 5.7 liter, unfortunately GMC decided to locate two freeze plugs behind the flywheel, and of course, one or more of the freeze plugs was leaking.
It appeared that the only option would be to pull the transmission to gain access to the freeze plugs and make a time consuming repair. I tried several products to repair the leak, none of them worked, they were just a waste of money and time. I stopped in at a local O’Reilly auto parts store and was discussing the problem with a sales person that just happened to also own a radiator repair business. He suggested K-Seal and stated that he uses the product in his business with an almost 100% success rate.
On his recommendation I purchased a bottle, although not necessary, I flushed the cooling system, added new antifreeze and a bottle of K-Seal, I was amazed that almost instantly, K-Seal repaired the freeze plug leak.
All I can say is, that your product is amazing, I will always carry a bottle in the vehicle. K-Seal was the only off shelf product that would repair the freeze plug leak, THAT SAYS A LOT FOR YOUR PRODUCT.

We received the following question which we were happy to answer with as much advice as we could:
“I have a 2005 Grand Marquis with the 4.6 V8.
The intake manifold has the water assembly in aluminum up to, with a gasket and it’s attached to the intake on the bottom, the intake is made of plastic. It is leaking from the gasket between the aluminium top and the plastic bottom. Do you believe your product will seal this leak?”
Some time later we were delighted although dare I say not surprised to receive a follow-up message telling us how he got on:
“I must say that I am very impressed, it did stop the leak and so far so good, I am amazed at how easy, cheap and how much money it saved me! Thanks a Million!” Nelson Leite USA
I bought this product while in a bind in Concord, North Carolina. I was on my way back from the Outer Banks to Omaha, Nebraska and shortly after I left the Outer Banks, my motorcycle starting puffing white smoke out of the right exhaust when I was at idle or when I started it. It got progressively worse, and by the time I got to Concord, I was adding about 2 cups of water to the radiator every 75 miles. If I stopped the motor, I had to pull the spark plug from the cylinder with the leak to clear the cylinder of water before I started it.
I stayed in Concord overnight for the NASCAR race there and did some internet research the next morning and found this product had good reviews and was available at the local O’Reilly’s Auto Parts store. I bought it along with some antifreeze. The instructions claimed you only had to add it to the radiator and it would fix the problem in about “1 to 3 minutes”. I thought, “yeah, right.” I put it in and I was right, their claim was overstated (barely), it took it about 10 minutes to work. After putting this stuff in, the white smoke stopped shortly thereafter, the cylinder no longer had water draining into it and the cooling system was holding pressure and didn’t need any antifreeze added.
Luckily, I wasn’t getting any coolant in the oil and the head gasket leak was only pushing coolant into one of the cylinders and burning it off. This stuff is spectacular and it saved me from being stranded out on the road or burning up a motor trying to get home. My motorcycle is a 1985 Honda Goldwing with about 110,000 miles and it runs as strong as ever. My ride from Concord involved a lot of mountains in Tennessee and everything worked flawlessly.
Anyway, I would obviously recommend this product to anyone with an older vehicle that might be starting to lose coolant, it is a cheap fix compared to having to tear a motor down and it doesn’t even require you find the location of the leak, just pour it in and see if it works. Based on the other reviews it has received, it appears this stuff works for some pretty serious issues, so it gets an A+ in my book. I am going to make sure I always travel with a bottle on board just in case. Daniel (Via Amazon.com)

Regarding K Seal in my radiator. I had a horizontal crack along the top front edge. My mechanic told me to try K seal.
At first it didn’t work and then he said to shut it down and make sure the coolant was all the way up to the very top of the radiator.
I thought because my reservoir was full that the radiator would be too but I was wrong. When I added water it worked immediately.
Seems to be a great product but I would definitely put in the general instructions to check the radiator level itself when it is cold and add coolant to the very top. - Robert McConnell (USA)

I purchased an old 1996 EF 11 -Futura in Melbourne ( Mentone) – The car was excellent owned by an old chap – however the Head gasket had blown and it was using water….the cost to fix was as you would know not worth it on a Old car.. may as well change engine ??
Anyway I flew down picked up the car drained the water took off the engine side of the top radiator hose poured your product in and some new Nulon coolant reattached hose filled up the Side tank and ran the engine for 5 minutes topping the side tank until I knew it was approx system full..!
I then jumped in the Old Ford and drove it to Euroa…via the Yarra Valley..I did not switch it off from point of K-Seal addition to Euroa
about 2 hrs.
I stopped there at the road house and after coffee etc I checked the system it was down approx 500 mils — I topped it up and drove it home ..to Springwood a distance in total of 926 kms …As it was Night time I had the heater on half for not causing air lock in the system between half taking off the top house and the coolness of the night drive home.
I did not check it other then a fuel stop at Marulan. .all seemed well in the Side tank and system gauge running cool…so did not open this time !
I checked the System in the morning no loss of water …….$35.oo got this car back and its still going —– The freight from Melb was to be in excess of $500……
K-SEAL Magic in a blue bottle…..All I can say it worked for me……And I have the spare bottle / I should frame the old one !!!…..

Hello, Just thought I would inform you of the success I had using your product! Car Rover 75 2.5 Litre V6 petrol. Coolant loss and ‘mayo’ on the oil filler cap. All external areas checked as well as common coolant loss issues with this engine but no sign of a leak. Suspected a liner problem and not head gasket failure after sniff test and compression. Car never would never overheat. One bottle of your stuff and 1000 miles later no mayo and coolant level steady. John UK

Thought you might like to know – got the K-seal yeaterday and treated my car last night. The garage floor was dry this morning so it seems to have worked and (fingers crossed) no need to replace the water pump for a while at least! Graham Robertson (Aberdeenshire)

Heater core went out in my 94 Isuzu,it had over 175,000 miles on it. Used K-seal per instructions and saved 300 bucks. Don’t under estimate this product. I’m not getting paid for posting this. I done my homework.
I wasn’t going to put something in my engine without first checking it out.

“Turns out, it was a blown head gasket. A bottle of K-Seal later, no more white smoke from the tailpipe” DJ Thump (Tweet)
08 July 2013
“We have used K-Seal on our own vehicles and can say unequivocally that it really works. We were surprised to see that K-Seal fixed our leaking cooling systems almost instantly. The portions of our cooling systems that leaked are now bone-dry.
Furthermore, K-Seal seems to have repaired head gasket leaks that we didn’t even know about, because both of our vehicles ran much more smoothly after the K-Seal.”
08 July 2013 “Brilliant product. Have used it in my Land Rover – just pour it in and go. Exactly what a girl wants, easy fix!”

I have an old 86 Dodge Ram Van 150 with the 318 engine I resurrected from non-op to go camping in. Discovered a blown head gasket. Researched many high priced competitors with bad reviews. Then K-Seal, low price with great reviews. Let tell you…
BUY IT – IT WORKS GREAT. I saved dumping the van and we’ve put it through some serious mountain driving in Idaho up steep grades. This truly is a mechanic in a bottle. Wonderful – Thanks K-Seal. YouTube Comment.

“I recently purchased a 1982 Porsche 924.
It had been left for dead three years ago. The garage said it needed a new engine because the owner drove it untill it overheated and died. The cost of repair was to high for the owner and he left it at the garage. I did some searching on the internet and found your product and I thought, “why not give it a try”.
I started the motor and white and blue smoke was coming out out of the exhaust as expected. I poured the K-seal in and in less than 60 minutes the smoke stopped, the motor did not overheat and it ran like a dream. I left it running for 2 hours!!, the garage owner could not believe it.
Thank you K-Seal for saving alot of time and money, I now own a classic Porsche and it’s running!!!” Jack Hoppe – Belgium
19 June 2013 “Can’t believe it worked but it did 3000 miles and going strong this is one awesome product and well worth it tryed many other types but this is simply the best by a country mile thank you k-seal for saving me money” Jordan Armitage UK

I just wanted to inform you that I had a radiator leak in my 1996 Toyota RAV4 with 290,000 miles on the odometer.
My mechanic indicated that it would cost me at least $500 in parts and labor for a new radiator. He said that my other option would be to try K-Seal for $16. He poured the bottle into the radiator and within minutes there was no more leak. What an amazing product which I did not know existed. Thank you for saving me the unnecessary expense for a replacement radiator. Louis Brandt USA
30 May 2013 “I have a 13 year old rover which was loosing water every day from the expansion tank,a friend showed me that I was losing it through the exhaust, and said It was the HG blown. so y’day I bought and used k seal,ran the engine for 20 mins but it still drained of water I thought thats that didn’t work… I filled it again last night and was very surprised to see it still full this morning!been driving round today and no water loss.” Tom Roe UK
22 May 2013 “I had a really bad leak in my radiator and I was going to spend couple hundred dollars repairing it, so I decide to give this stuff a try and in less than 5 minutes my radiator stopped leaking. More than easy to use just pour the container in the coolant reservoir and voila! I feel more than happy with it so I felt obligated to write and say thanks because it saved me tons of mobey” Youtube Feedback
09 May 2013 “Now here is a product worth its weight in gold. Costing very little but it does such a valuable job. Originally I bought some for a vehicle I had which a mechanic had said had a cracked head. I was so pleased with it that I used it on two other vehicles as a matter of course as a preventative measure. I don’t consider it to be like Radweld, that’s a product I have never been really happy with, as this is more use in facilitating preventing more major engine work.
And it is so easy to use, just do as it says on the “tin”. Highly recommended.”
ebay Buyers Guide for K-Seal
07 May 2013 “Just wanted to join the lot of satisfied customers from using your K-Seal product. I have a 2003 Range Rover and had to get a water pump repaired. After the repair, I took my truck home only to find out that I was still loosing coolant and my “Check Coolant Level” still was coming on. I took my Range back to the mechanic and he gave me the dreaded news about there was a crack in my engine block. Went to the Range Rover forum and heard a few guys talking about K-Seal so I figured what the heck. Stopped by O’Rileys an picked up a bottle and within 10 min no leak!!!! I know this sounds like a marketing ploy, but I am a chief marketing officer of a digital entertainment company and I rarely comment on any product, but I was so blown away with how quickly it worked and I still do not have any problems! When my mechanic called I just knew I was looking at $2500 to $6k because nothing on a Range is cheap. I was ready to go and buy another car. Thanks to the guys at the RangeRover.net forum! Thanks K-Seal!!!!!!!” Gregory Jordan USA
29 Apr 2013 “Have an old jcb 3cx The head gasket was well and truly blown Fired in 3 little blue bottles of k seal Hey presto straight away digger is back in action Great product Thank You.” Seamus Mackey
09 Apr 2013: “ this K-seal fixed a head gasket leak in my wife,s audi a4 and my f150 rad. Thank you.” Dave McGregor
08 Apr 2013: “As promised my finding was exactly like you said and although the price of £11 for the small bottle it has saved me a probably hefty repair bill & going without my car . You can say I’m a very HAPPY CUSTOMER + big thanks”. Frank Gardner
02 Apr 2013: “Impressed! had a 1999 Jeep Grand Cherokee 4.7 with a timing cover leak. Replacement for parts were quoted at $760 for cover and $80 for gasket not counting installation. Used k seal with reservation but one bottle and ten days later k seal delivered. Wow what a relief for me and my wallet. Thanks Pat for urging me to try it”. Stacey Brignac USA
27 Mar 2013: “Just a quick line to say I warmed up my car left it 10 mins and poured one small bottle of K-Seal into my radiator. I then ran the engine for 10 mins with heater blower on full. I turned off the engine and left it overnight. Sunday I drove to Jerez Moto Gp circuit to watch the testing stayed in Jerez overnight and returned home yesterday after some 200 miles. This morning I checked the radiator and there was no loss of water. I then checked the engine oil dipstick and its clean with no sludge on it. What a great result!!!” Tony Fox
19 Mar 2013: “Hi as a former mechanic I’ve successfully used your product numerous times with great success even when I’ve looked at water pouring from radiators and said don’t think this will work but it has. Anyhow I’m no longer work in the trade but I used your product on my car a few months ago and it worked fine today however it’s started leaking from the same place as before so I have bought another k-seal this stopped the leak again” Chris Hodkinson.
27 Oct 2012: “Just tried your k-seal on my 1994 4 runner with new head gaskets but still had water in the 3rd cyl. I knew it must be a crack in the head. Did not want to pull the engine apart again. Found your product and put it in and after 10 min no more leak. Thank You Very Much. ” Ken Hanson.
17 Oct 2011:“Last winter I had to leave the little grey fergey outside although she had antifreeze in she still froze up leaving a small crack in the block. Just one bottle of the little blue miracle did the trick. She is still running fine. Many thanks for your wonderful little blue bottle” Andrew Shelton, UK.
16 Oct 2011: “I just want to say that I am really impressed with K-Seal. I have a Toyota with a bit of a leak. Being in a family, I have no spare money to replace the car radiator. I tried some of the K-Seal stuff and watched the leak stop over a few minutes whilst the engine was running. Its amazing stuff. Funnily enough, the heater matrix in my other car (Megane) has started leaking and the first thing I thought of trying is grabbing a bottle of K-Seal for it! Keep up the good work!” Andy Dixon, UK.
29 Sept 2011:” I’m like most, seen the mess on the garage floor where the radiator had leaked but not in a car but in my prized 1000cc Yamaha Thunderace Super Bike. I was looking at having to buy a new radiator and at considerable cost, I had no alternative but to leave it in the garage and save up to buy a new radiator. That night I seen a post about this amazing stuff KSEAL, and how it worked on almost any engine with a radiator leak. Well I was so unsure if I wanted to put this into my bike but I read all the information and did….Well in a matter of 5 mins the leak had stopped and the Radiator had been sealed. I was astounded and still am. To this day the bike still runs with it in it and no leaks at all. I posted this to other sites to tell them how great this product is. I am so happy it let me ride my bike with out any issues ever again. It does what it says and more so it works on a high performance bike engine which revs to over 11500 rpm! And still keeps going. Andy Robertson, Glasgow.
27 Sept 2011:” 1998 Ford F150 with 250,000 miles, decent leak in head gasket, within 15 minutes the leak was completely plugged, no other product I’ve used in this truck has been able to do this!” Jeremy E, MI, USA.
22 Aug 2011:“Thanks for saving me from a very expensive heater core repair which i really couldn’t afford at this time with cold weather right around the corner.You have a great product.” Mr Konschnik, PA, USA.
07 Apr 2011: “We have been selling K-Seal since 2006 and have noticed the volumes have been increasing month on month, quite clearly this product is becoming very established in the Trade. Undoubtedly it will become the new ‘Hoover’ of the cooling system leak sealants. The bottle is bright and has clear instructions – it does what is says on the tin!” Simon Mannell, Devon.
28 Jun 2011: “Just wanted to say thank you, it fixed a 2000 Monte Carlo head gasket leak and on the same day it also fixed my 1998 Volvo S70 heater core leak… Unbelievable that in one day, $40.00 worth the K-Seal fixed two vehicles! Thank you, thank you! K-Seal saved my ass.” Scott Hamel, Michigan, USA.
13 May 2011: “The first time i used the product was as one of my sons was about to go on a long journey. He came in to say water was pouring out of his radiator and he was in a rush. So out came the K-Seal for its maiden test and it came up trumps. A truly great product thanks very much. ” Mike Thornton, Merseyside.
29 Mar 2011: “My 1997 Hyundai Sonata 3.0 V6 had been leaking from the radiator and water pump for several weeks, over the course of the weeks I had tried two different sealants of which neither had any effect. I was about to endure the trauma of finding out how much replacing the parts would cost when the spares shop guy suggested I try K-Seal. I was a little dubious bearing in mind I had tried two sealants and K-Seal cost twice as much. Knowing that I really couldn’t afford the doubtless hundreds of pounds replacing the parts would cost I decided to try it. I put it in immediately and then drove home, left the car for a few hours then came out to see what had happened fully expecting to see a pool of water under the car. The ground was bone dry, it’s been three days now and still not a drip. It has been well worth paying that few extra quid for K-Seal.” Peter Ward, Stockport.
18 Feb 2011: “Hi, just a quick thank you! Had water pouring out of bottom of radiator, was told by Autosave to try this product. Stopped leak immediately.” Geoff Willis, UK.
21 Jan 2011: “Hello! Just wanted to share my experience of your great product, K-Seal. My 99 Chevy Malibu recently blew a head gasket. The car had 220,000 miles with about 130,000 on the present engine. It was developing pressure in the cooling system and pushing coolant out the overflow at a rate of about 1 gallon per 20 miles. I had changed the head gaskets in this car before and 15 hours of my time plus $300 parts hardly seemed justified for such a high mileage vehicle. Plus my family like most others have felt the pinch of the economy and a new car payment is the last thing we need, but it seemed like we would have to get a newer vehicle. That afternoon I was in Hovis Auto parts in Butler and saw your product. It was about $12 and I have dealt with Barrs leak style products in the past and they NEVER worked. A fool and his money are soon parted flashed in my mind, but I figured what the heck, I’ll try. I poured it into my overflow and drove home. Then out to my parents house 15 miles away. To my amazement I only had to add 1 quart coolant, then it stopped using coolant all togeter! It is now 3 months later and my $12 repair is holding fast! I never would have believed it had I not done it myself. Awesome product! Thank you so much!” Curtis Wallace, PA.
01 Dec 2010: “This stuff is brilliant. I had a 325 Bmw that was leaking from the back of the head, garage advised new head gasket. I put this in and it never lost another drop of water, the leak was that bad I was putting in a few pints of water a week. Worth every penny, saved me a massive bill.” keefred (YouTube comment)

19 Oct 2010: “I followed the advice you gave and put the K-Seal into the cooling system on the Smart car. The product worked very fast (just a few minutes), sealing the system and stopped us having to remove what was a considerable section of dashboard in order to get to the faulty heater matrix. We feared that the car would be off the road for sometime for the matrix to be removed, but it was back on the road the same day. Thanks again.” Mike Hewson, Buckley.
19 Oct 2010: “This is the first recommendation I have ever written about a product. I am over the moon with your product K-Seal which I have just used. Last weekend I determined that my 5 year old Rover 45 had a leak in the head gasket. I was gutted because it’s only done 44 thousand miles and I don’t abuse the car when driving it and I look after the car, maintenance wise. I was on the internet on Sunday, eBay actually and was looking for a head gasket for my car when your product was being advertised. Quite frankly, I was quite sceptical the claims it was making, to repair the leak and guaranteed it to last for the life time of the engine. Received the small plastic bottle on Tuesday morning, I just shook the bottle well and poured it in to the expansion tank on the cooling system of the car and ran the car to normal running temperature for a few minutes. I immediately noticed that the idling tick over became a lot smoother and quieter, I could not quite believe it. I left it for a further few minutes and took the car out for a short run. The car ran a lot smoother and quieter when idling, I just couldn’t believe it, and ‘It did exactly what it said on the tin’. Thanks, great product for the price, saved me a fortune.” Brian Clark, UK.
19 Jul 2010: “I have an old 86 Dodge Ram Van 150 with the 318 engine I resurrected from non-op to go camping in. Discovered a blown head gasket.

24 Jul 2010: “I just wanted to say what a great product you had. I was diagnosed with a blown head gasket, did not hit oil area and only heads, as it blew steam from the tail pipe. 5 minutes after using the product as described it cleared and cooled down and after an hour of running around town, ran like a champ. What a great product. Funny neither one of the two mechanics bothered to tell me about it. The truck is a 1991 Explorer, and both mechanics wanted me to spend between $1000.00 and $ 2000.00 to replace and repair, I paid $1500 for the truck and only wanted to use it for a year til i coud buy a new one. I have had it for 6 months and because of your product will have it for the next 6 months. Thank You.” Dodd Pinkha, California.
09 Jul 2010: “I used this amazing product on my Yamaha YZF Thunderace Motorcycle when the radiator core leaked badly. WOW it stopped it and I have been able to ride all summer thanks to your great product. Can’t recommend it enough. Thanks”

07 Jun 2010: “I was recently on holiday when my 2.8 pajero started boiling over and a quick visit to a garage confirmed my head gasket had gone. A friend of my told me to buy some sealer that you put in the radiator so i bought k-seal and to my surprise it worked a treat. I was able to tow my caravan back home 220 miles without a problem saving me hundreds of pounds. Thank you so much for a great product that does just what it says on the tin”
Geoff Carlisle, UK.
08 Mar 2010: “I have a 318i bmw which was overheating. After replacing the thermostat (due to the bottom hose being cold) the car was still rapidly overheating. When removing the oil filler cap I could see milk on the cap and on the upper rocker cover. My heater only blew cold air and I had water coming out the exhaust pipe end. It looked obvious that the head gasket was leaking or the head was cracked. I found your product on an internet search. It was most helpful to find you also listed local stockists. [I added the K-Seal], started the engine and proceeded to drive around the block. Within 30 seconds the heater started to blow hot air, so I knew something was happening. After 20 mins of driving still no overheating. On my return home, there was no water spitting out the exhaust pipe end, and after checking the oil filler cap although still milky the water had evaparated from the rocker cover.
I just wanted to write and thank you so much for your internet coverage enabling me to find your product. I would also like to add that if you have a similar problem to mine, give K-Seal a try. It really works and will save you a huge amount of money and save the need for a head gasket replacement. Thank you so much.”
Rachel Thomas, England
02 Mar 2010: “Just had to send a big thank you for fixing a leak in my Fiat Seicento Sporting radiator, it really does do what it says! The leak was cured in 1 minute flat and saved me the price of a new radiator (£100). Thanks again!”
Dave Locke, UK.
04 Dec 2009: “Merc – Econic HGV with an untraceable radiator leak losing 2 litres a day. Added K-Seal HD on the 20th November and the water loss totally stopped.”
Peter Baldock, Kent.
02 Dec 2009: “I have been in the trade 36 years and always disbelieved in quick fixes. Got an eco tec Corsa T reg 90.000k with head gasket failure causing misfires and steam in the exhaust. A mate suggested I try K-Seal which I did and within 15 mins no steam. The next day it started it up spot on with no sign of steam. Thanks to you it’s sorted. Sorry for being a disbeliever and I will spread the word.”

David Metcalf, Lancashire.
31 Apr 2009: “Just to let you know that the K seal I purchased from you realy does work, as I had a serious problem with my Range Rover head or head gasket, and I was looking at a £1000 repair bill or a new engine, but now the engine is running normally. Just completed the first 100 miles after the repair and all is well, so K Seal really does work. I will have no problems recomending K Seal to any one with a simular problem.”
Brian Perrin, Isle of Man
07 Apr 2009: “Just wanted to say how impressed I am with K-Seal. I have a rover 414 with HGF, in fact water was shooting out the front of the block when it was running and the water was pressurising from the failure. After pouring K-Seal into the header tank ALL symptoms went away and the car loses NO WATER AT ALL! I’m quite frankly astonished at how well it works. Thanks for the fine product. Cheers.”
Andy Hill, UK
21 Feb 2009: “I’ve added it to a 1993 Mk3 Astra 1.4MPI and IT WORKS! The car’s done 350 miles since, and no topping up has been necessary. A brilliant product. Replacing the head gasket would not have been cost-effective (either in time or money) due to the age of the vehicle. Although the car’s done 128,000 miles I hope to get a few more miles out of her yet!!
Clive Holterman, UK
13 Dec 2009: “I had a leak from the heater matrix on my Fiat Marea, and did not relish the prospect of a £250 job to replace it, and the fact that most of the dashboard would have to come out. I was recommended K-Seal by my local auto spares shop, as the proprietor had used it himself. My car was losing about a litre a week, so it was certainly worth a go. I popped it into the header tank, and went on a 30 mile trip at once. Since then, the car has not lost a drop, and the heating and cooling system work fine – I just need to wait for the carpet to dry out, and everything will be back to normal. This stuff really does work, and I’ve got another bottle in for the wife’s car, just in case!”
Glenn Allan, Wales, UK.
03 Feb 2009: “HI. JUST DROPPING YOU A LINE TO SAY K-SEAL REALLY WORKS. I HAVE A 4.6 HSE RANGE ROVER AND IT WAS LOOSING WATER BUT I COULD NOT FIND WERE FROM. SO I BOUGHT A BOTTLE OF K-SEAL, PUT IT IN AND IT HAS NOT LOST ANY SINCE. THIS WAS IN MAY 2008. BRILLIANT STUFF.”
DON HUGHES, UK
13 Jan 2009: “I bought K-Seal the other day thinking it would not work – as a last resort after changing 2 headgaskets, never really given additives such as this much credit. I have a moderatly tuned Nissan 200sx s13, stuck the K-Seal in the rad,(only about half a bottle would go in), smoke stopped totally within 10 mins. I STILL can’t belive how good this was! Totally astounded.
Thanks for making a Great Product and saving me hundreds of pounds! I promise I won’t doubt K-Seal’s abilities in the future!!!”
John McNeil, UK
17 Dec 2008: “Hi guys. Just used your product on my 1800 diesel after the radiator blew a leak. After I tried 2 other inferior radiator sealants that did not work and I have to say well done. Within 5 mins all was well and the levels remain static. The k-seal was recommended by a soldier who says nearly every vehicle in a war zone carrys these as it’s the only thing that will plug a bullet hole. Nevertheless well done and well played”
Brian Reed, UK.
08 Dec 2008: “I purchased some of your K-Seal and it does exactly what it says on the bottle. The best thing since sliced bread.”
Nigel Webb, (Taxi Driver), UK
03 Dec 2008: “Well, what can I say about K-Seal. I was losing coolant from my car at a rate of approx 1 litre every two days in my 97 Golf and was dreading an expensive repair which I just couldn’t afford after getting the alternator replaced a few weeks ago. I thought I’d identified a leak in one of the cooling pipes and thought that considering I thought I knew where fluid was escaping I might as well get it fixed properly and took it down the garage on Monday. The pipe was replaced and I went away happy and £50 lighter. Two hours later the coolant warning light was back on and the coolant level was well below minimum again. I’d seen K-Seal on eBay and read some good reviews and after leaving a few sheets of paper underneath the engine knew I was losing a lot of fluid from the radiator. I couldn’t afford to get it repaired so bit the bullet and despite scepticism picked some up this morning. I’ve done 80 miles since then (first time I could go out of town without topping up the header tank) and have just checked and the coolant level has not changed even slghtly. I can’t say at this stage whether the problem will recur but I’m going to sleep a lot better tonight. I would, and will, recommend K-Seal to anybody I come across with a coolant leak. Maybe it won’t work for all but it looks like it’s certainly worked for me! Thanks.
Mark Smout, UK.
02 Dec 2008: “I sucessfully used your K-Seal product on my car earlier this year and so far 6000 miles and no problem with coolant loss.”
Phil Peacock, England.
01 Dec 2008: “Just to report 100% success,many thanks.” Philip Constable, UK.
02 Oct 2008: “My ageing Rover 620 gave up the ghost 250 miles way from home. All the water had gone from the system. A mechanic told me it was time for me to buy a new car as the repair to the leaking head gasket was going to be over £500. A quick call to a mate at home, pointed me in the direction of K-Seal. Wow. I was able to get home, and was amazed that I hadn’t lost any more fluid. Now I am home I need to replace the coolant as there is no longer any anti freeze in the system, But I am definately going to throw a bottle of K-seal in too. It really is a magic fluid.” Rob Usher, UK.
28 Aug 2008: “Having seen the results I am very impressed with this product. I think it would be advisable for any workshop to stock K-Seal, as more times than not, it can solve a problem quicker and at a smaller cost to the customer than a mechanical repair.”
Commercial Vehicle Workshop Magazine.
21 Jul 2008: “My Discovery TD5 overheated and started using water by the gallon. Garage tested the radiator and there were exhaust fumes present so they replaced the Head Gasket costing £350. 2 days later the same problem, every 20 miles the radiator overheated and used all the water. Back to garage and was quoted £1200 for a new head, they thought it was porous or warped. I went home and looked up my options on the internet and found K Seal, ordered it straight away, even though it was the least expensive and the competition all said they were the best. When it arrived, poured it into radiator, topped up radiator and let car run for 10 minutes. 1500 miles later and it has only used a cup full of water and never over heated or missed a beat since. What a product, what a money saver, what a life saver, Thanks.” Kenny Fraser, Scotland.
21 Jul 2008: “Just to let you know my SAAB had been leaking water since I have owned it even after a heater matrix change and a core plug change costing several hundred pounds. 1 small bottle of K seal and all is well several months later and the SAAB now holds water at long last!! Add me to the list of satisfied customers. Regards Mike Strutt, Milton Keynes.
03 Jul 2008: “Hi, i recently used Kalimex to sort a problematic head-gasket on a Land-Rover Freelander.. while on holiday in the Lake District and as usual i said i would sort it out properly when we got home to to Cornwall, 350 miles away… but its still ok so i’ll leave well alone… and its saved me a fortune…… But to add to that , i recently MOT’d my daughters Renault Megane, and it failed miserably on the emissions test…. so instead of replacing the lambda sensor and catalytic converter, i tried your new product..CATACLEAN, now this stuff is a miracle worker, when i took it back for re-test, it PASSED with flying colours… the MOT tester asked what i’d done to get the emissions so low… then i told him about CATACLEAN……
And to top this off, a friend from Worcestershire phoned me last week to say his Discovery-TDi had failed MOT on emissions, he couldn’t find CATACLEAN anywhere in Kidderminster, Worcestershire… so i put a bottle in the post,, voila, his 4×4 passed the MOT… he was as amazed as me, as most people are sceptical about these miracle fluids in bottles…. but i’m convinced 100%.” STEPHEN HAYWOOD, CORNWALL.
19 Jun 2008: “We were skeptical of any product that says it is a permanent fix, but we were so impressed by K-Seal that we ordered a second bottle for our son. I would not be afraid to use this product in any engine. I was a mechanic for 20 years and never believed in ‘Mechanic In A Can’ until K-Seal. Thanks.” Jack Smith, Texas.
28 May 2008: “I recently used K-Seal on my ’98 Subaru legacy 2.5 4cam with a manual box. I was losing a bit of water either through one of the head gaskets or a tiny crack, I am not sure which. I purchased some K-Seal and added it to my coolant. The results where nearly instant and really astonishing. This was great news for me as the engine had only clocked about 15K. It is a really big job to take the heads off a Subaru as I am sure you know and you have saved me hours of work and or hundreds of pounds. I am very pleased and will tell all my friends about this. People can be very sceptical about all aspects of liquid engineering, but I am sure if they used your products they would quickly change their minds.” James Green, Lincolnshire.
19 May 2008: “Life Saving Products. I was 200 miles from home when my radiator started leaking. I purchased a bottle of K-SEAL and within minutes was on my way. That was 4 weeks ago and I have not had to top up since. THANK YOU.” David Bain.
22 Apr 2008: “I would like to inform you of the success I have had with your K-Seal product. I have a Rover 75 2.5 V6 and some weeks back it developed overheating and coolant loss problems, I took the car to a garage and they did some diagnostic tests and told me the bad news that the head gasket had gone and quoted me almost £1,000 to fix it! Having picked my jaw up from the floor I searched the internet for other solutions and discovered K-Seal. I followed the instructions, added the magic potion to the cooling system and took the car for a 15 mile run just make sure I had given the stuff every chance and I admit, I was doubtful at the outset, but I’m pleased to say it fixed it! I have now done over 2,000 miles in the Rover, some motorway, some town and traffic queues and it runs fine. RESULT!
Many thanks, Great Product. Regards, Neil Hardy.”
17 Apr 2008: “I spoke to MD of K-Seal in the UK about my problem with a Range Rover TD6 2003, leaking coolant at a litre a month. He said K-Seal would fix it, I bought some that day, put it in the header tank and lost any coolant since and that was over a month ago. What a fantastic product and what a huge saving compared to going to the main dealer for diagnostics. THANK YOU VERY MUCH.” James Stuart, England
31 Mar 2008: “This is the third time that I purchased this product from you because your product is unbeatable when it comes to cooling system repair” C. Mercieca, Malta.

01 Feb 2008: “I didn`t think miracles happend but thanks to purchasing your K-Seal it has. It helped my dad save a fortune repairing his leaking head gasket on his Rover 416 K6 engine. Unbelievable cheers thanks for producing a product that realy works.” Steven Thomas, UK.
18 Nov 2007: “Dear sir. I would like to take this opportunity to congratulate you on your excellent product. The vehicle I drive is a Mitsubishi Pajero which recently had a radiator fail. This was not a problem as the radiator was replaced. Due to the colder weather being forcast I decided to install anti-freeze at the % stated by the manufacturer. This resulted in the vehicle making a considerable amount of white smoke, not ideal. This white smoke was the anti-freeze being sucked into one or more of the cylinders, not being fully combusted. The on going outcome, the nearest motor factors, Whiston Motor Factores, stated that your product was one if not the best! I cannot state how high a spec has been achieved by your product.” Mr G Birch, UK.
30 Oct 2007: “I got some K-Seal from our local garage repair shop for leaky head gasket and it’s working great.” Dave, UK.
13 Sept 2007: “Just a thankyou – purchased from Finishline, and so far so good ! Seems to have done the job (rare nowadays) …in since 06/09/07 with no symptoms of failure to date.” Ged, Doncaster, UK.
31 Aug 2007: “I own a Vauxhall VX220 (A British hand built sports car built beside the Lotus Elise/Exige). With a 2.2l GM Ecotec engine designed by Lotus and built primarily in the USA. The engine recently suffered from a cracked cylinder head above the spark plugs whilst on a routine service. I originally bought K-Seal as a ‘get the car home’ cure, however im delighted to say that over 1000 miles, driving how the car was made to be driven (very hard), K-Seal has held all that i’ve thrown at it!” Edward Butler, England.
27 Apr 2007: “Kalimex K-Seal I’m Impressed ! Now as you guy know I have been around the block a few times, not that I am cynical but it takes a lot to impress me, K-Seal has. My mate bought a Rover 800 2.5 KV6 at auction —it ran great for the first two weeks then the rad core disintegrated and he truly cooked the engine — not a good idea in the early version of the KV6. New radiator fitted and he still had a case of slowly disappearing coolant and signs of water in the oil and oil in the water — As replacing a head gasket is no joke on the KV6 in the 800 so in went a container of K-seal. The result was amazing — no coolant loss and even more amazing no more emulsion in the oil side. K-seal is completely different from Radweld or Barrs Leaks type products neither of which I would use on a modern engine — Back in the stoneage Radweld was fine for emergency repairs on radiator leaks on older cars provided you removed the thermostat first, while Barrs Leaks had so many solids in it blocked the raddiator cores up.” Posted on the locostbuilders.co.uk forum.
26 Apr 2007: Dear Sir/Madam. After being quoted £60 for a new radiator, giving K-Seal a try was an easy option. So I tryed it on my J-Reg Transit 2.5DI and hyes! It seems to have worked. Thank you, Steve Cummings, Suffolk.

30 Mar 2007: Hi there, I have just used your K-Seal product in my Rover 216 with a K-Series engine that had a leaking head gasket (A common problem on these engines) so far so good, no more coolant loss into the sump ! Thanks. Rob Williams, Flintshire

11 Feb 2007: Hi. Just used K-Seal on a 1998 Escort 16V Zetec with badly leaking water pump,did,nt expect it to work but it has and will allow me to run without changing pump at this stage which involves considerable work because timing belt has to come off. Great Product. Dave White, Newark.

08 Oct 2006: Hi, I tried K-Seal on a water leak on my Fiesta 1.25 Zetec 2000 model year. The reason for this, was that because of Air Con pipes, I could not see where the water was coming from. I suspected that it was the water pump. I used K-Seal on 28th Sept & to date have no more water leak. Thanks for a product that does what it says. Tony Kula, Stafford.
03 Oct 2006: 16th September 2006. Added K-SEAL to a leaking 10 year old radiator on a Citroen Xantia 1.8 16v. Took car for a run along the local by-pass to get coolant up to operating temperature. Checked later and coolant leak stopped. Interestingly, on 29th September had cam belt changed and at same time took opportunity to have the water pump changed which required emptying of the coolant in the radiator and subsequent refilling with fresh anti-freeze. The K-SEAL fix still appears to be working as the radiator is still not leaking. Stephen J Bradley, Crewe.
19 Sept 2006: Posted on Lexus Soarer Owners Club forum lexusclub.co.uk “the stuff really works! My old man used this on a diesel shogun with a cracked block and it is still running over 18 months later. My 325 beemer had the headgasket go, poured this stuff in & 3 minutes later it was sorted, duly continued to thrash the thing off the limiter on a daily/ hourly basis and it never complained.”

28 Aug 2006: have used K-Seal several times and found it to be the best coolant seal on the market after using a multitude of products over the many years in the motor industry.Used on leaking core plugs successfully and also cast in steel pipe fittings where the fittings had rusted through.
It goes without saying that I am very impressed with K-Seal and curious to see whether other Kalimex products are as good. Thank You. louis grainger,

08 Aug 2006: Dear Sir or Madam. I have a Chrysler PT Cruiser which is not very old but out of warranty it developed a bad leak in the coolant radiator between the plastic header and alloy core. No way I’m told to repair it but to replace with costly new one. I purchased a bottle of K-Seal, poured it in cooling system and like magic after first run completely sealed and water tight and remained so. Mr G Swift, Barnsley.
01 Aug 2006: Dear Sir or Madam. I bought Kalimex to fix my heater matrix which had a bad leak. It stopped within two minutes which was four weeks ago. I’ve found the Kalimex very good as my heater matrix has remained bone dry. Job was a 1994 [Peugeot] 405 diesel. Cost at the garage to fix it over £200, Kalimex price £10.95. Thanking you very much. Mr Tabern, Lancashire.
01 Jul 2006: Quote from vauxhallownersnetwork.co.uk “Emailled the company lastnight & got a reply this morning. The only local supplier is in South Shields, so I got a mate to drive me over today & get some. £9.38 (incl vat). Got home, stuck it straight in, bump started the car & went for a drive, as directed to by the bottle. 5 minutes later… I no longer have ANY white smoke coming out of the back of the car, & no loss of water. The stuff is amazing. From my experience so far, I’d highly reccommend it. I went out this afternoon, 25 degrees c, & stuck in rush hour traffic on the A1. Never did more than 15mph for around 20 minutes. The car reached it’s usual temperature, & stayed there. As soon as the traffic cleared, got up to 70mph, & the temp dropped back to just over 90. If the stuff was going to goose my radiator, or just didn’t even work, that test would have shown it’s faults, I’m sure, but no problems whatsoever. K-Seal: Does what it says on the blue plastic bottle
19 May 2006: what a great product used some sh*t in my time but this done what it says on the bottle \\\\we were in the middle of nowere in a 80 silver shadow rolls with a split radd got a bottle kalimex from a farmer of all people who said he bets it dont work bit like the old rad weld stuff well i tell you we were both gob smacked when the radd held water well done and thanks from me and a suprised farmer–\\\\yours graham (London)
15 May 2006 Hi. I used K-Seal on the water system of my Rover 400 series, as I had a water pump link, and was loosing about 3 ltrs of water every short journey.
Put K-Seal in the overflow tank as directed, and as I let the engine run, I could see the water leak underneath dissappear, it’s great thanks.
Sam Malone, Kent

21 Mar 2006: I used k-seal on March 20th at Lancashire County Council workshop, Whalley near Blackburn. K-seal was used to seal a leaking head gasket in a Daewoo matiz engine and it has worked successfully. Nigel Winder, Lancashire.
29 Nov 2005 Hi Mike. Thanks for delivering the above so promptly, we received it on Saturdaymorning. We used it to repair a leak in the head gasket on our Rover 400 1999car. My husband is very pleased with the result as it had sealed it in amatter of minutes, and he has recommended it to his motor mechanic friend whowas unaware of it when he spoke to him late last week.I would like you to enter us into the monthly draw quoting ‘IDEA 5501′.Thanks again Regards Brenda
13 Nov 2005 About 6 weeks ago my 1935 pre-series Morris Eight developed a small leak in its cooling system. I discovered that there was a leak around one of the front core plugs. The front core plug is not easy to get at as there in not much room between the engine and the radiator, so I looked for a solution that did not involve removing the front of the car, or the engine. I knew products like K-Seal existed but I coudn’t remember the names of any of them. I searched the internet for engine sealers and I found a company advertising bottles of K-Seal that I could order on line. I placed an order and a few days later, a small package arrived in the post containing the K-Seal. I poured the contents of the bottle into the header tank and the leak appeared to stop almost immediately. That was about three weeks ago, and I haven’t had a problem since then, thanks to K-Seal. I have attached a file containing a picture of my car so that you know what it looks like. If I come acroos somebody else with a similar problem I will definitely recommend the use of K-Seal. Thanks. Adrian Mitchell
06 Nov 2005 Dear Sir/Madam,Thankyou reference IDEA5501Your product was amazing. I used it to repair a crack to my cylinder head on my nissan cargo import. I had been quoted £650 for head repair and gasket. I used this product and it did the job curing all the leaks. I am totally in your debt and would recommend your product to my friend’s.Mel ParkesLincs.
22 Aug 2005 Mark Sallows (Carsem Europe)(Land Rover Discovery 2 (2000 year model) with a leak in the heater matrix). Hi Mike,Just a quick mail to say that the ‘K-Seal’ did it’s job fantastically, I cleaned out the system, filled half full, put the ‘K-Seal’ in and topped up and bingo…..no wet feet and no leaks in the engine bay……….I have been promoting your product to everyone I talk to and sold about half a dozen bottles for you……I need your advise again though. A colleague of mine has a Mazda 626 2.0L with a small blown head gasket (still driveable just..), will the ‘K-Seal’ be up to the job of fixing the leak in the gasket or should he use ‘Seal-Up??Please advise so he can buy the right product of yours and get his car backon the road Cheers Mark
01 Jul 2005: Enquiry From : Andy Lees, Huddersfield,West yorkshire,. I have just used K-seal in my 1995 Omega to seal the head gasket and it worked a treat what an excellent product u\’ve saved me a small fortune. Thank you.
01 May 2005: Enquiry From : Barry Dowler : Hi, wrote to you earlier, just purchased your product K-seal and it has cured a significant water leak, well chuffed!!! I will be recommending your product to all my 4×4 offroad pals…. Thanks Barry
11 Apr 2005 Enquiry From : Rob Gilfoyle Recently purchased K-Seal for my Rover 25. Recommended to me by my uncle who is a Motor engineer in Derby. Car symptoms were misfiring from cold start, excessive steam/smoke from exhaust and frequent top ups of water expansion tank. A local garage informed me I needed a new headgasket so tried uncle’s advice first before forking out for an expensive repair (approx £350). K-Seal so far has worked wonders, all the above symptoms have just about subsided and the car runs a lot better overall. Many thanks.
04 Apr 2005 Dear KalimexI. am writing to you about the amazing results I have had with your K-Seal product.I have a Cavalier Turbo Diesel, which I have owned from new, has been very well looked after, but has a hard life including ‘on the limit’ towing of a caravan. The car has covered circa 180000 miles.A while ago, it started to use approx half a coolant bottle of water per fortnight, started up on three cylinders and was generating a fair amount of blue/white smoke and generally running ‘rough’. All the classic symptoms of head gasket trouble, yet the engine oil was not being emulsified, there was not any gas in the coolant water, or visible water seepage.The estimate to renew the gasket was circa 500 pounds, with not absolute surety that was the problem – compression was normal. I had heard good reports from several sources as to how good the product was, so decided to give it a try.The result was fantastic, with the water loss stopping, starting up properly, and no more smoke than is normal for a diesel. The only thing that I can think of is that there was either a leak or porous casting on the atmospheric side of an inlet valve, and the water was going in via this route and giving the combustion problems.A big concern prior to its use was whether the engine would run hotter afterwards due to reduced heat dissipation by the radiator, something that is very important to avoid for ‘on the limit’ towing. This has not happened.A great product that has saved me a fortune, and the car runs beautifully. Yours sincerely Larry Sloman Watford Herts
26 Mar 2005 Hallo Mike Just to let you know the Audi hole is bunged, the customer is so happy I thought he was going to kiss me……I have given him your address, so he may pop round and kiss you instead, Thanks for your help, good result all round. Have a good Easter Cheers Paul

16 Jul 2004 Enquiry From : Justin Knowland. Just to let you know I have just bought an existing car parts retail outlet and am stocking your products through not only personal recommendations but from my own experiences. I had a problem with the heating system on my 1989 BMW 520i which over several weeks caused the radiator to burst a leak & become unrepairable, then split the top hose so I used Seal-Up & haven\’t had a problem since. Maybe if I\’d used it from the start I wouldn\’t have had a bill for a new £300 radiator! Thanks,Justin
