K-Seal coolant leak repair is scientifically tested to seal cracks and holes your car radiator.
If a car’s radiator overheats, this will probably be a direct result of an overheating engine. It is unlikely that the car radiator itself will overheat and cause further problems for the car owner, but if it develops a blockage or a leak the effects can cause significant run-on damage to the overall engine system.
Radiators are comprised of long tubes through which coolant circulates. The primary cause of an overheating radiator is debris and sediment building up inside the tubes and causing a blockage. This then means that coolant cannot pass through, causing the radiator and subsequently the engine to overheat.
If a radiator does become blocked, you will need to flush it out so that coolant circulation can continue uninterrupted. You should flush it regularly anyway – if you don’t, it may begin to rust and develop the small holes and cracks that lead to coolant leaking out and the engine overheating in the same way it would if the radiator were blocked.
K-Seal can help in sealing those holes – simply add it to a refill of coolant when it is poured into the system and the microfibres and particles in the solution will find the holes and seal them automatically without further blocking the system.
When flushing the coolant out, remember to catch it in a pan or bucket, as it is poisonous to any animals or children that might be exposed to or ingest it.

Great fix for a leaky radiator…K-Seal…available from most car accessory shops. I had a slight weep (dripping on floor after a run) from between the aluminium and the plastic side tank on my last Ram, put a bottle of K-Seal in then fastened my caravan on to Ram, and set off to Billing Northants 130 mile, checked when I got there…leak gone. Sold my Ram at 22,000 mile 4 years later with no further problems, it’s fantastic stuff 🙂View more case studies
