For K\u2011Seal to work effectively it needs to be exposed to an atmosphere. This can be externally or internally (across the head to the cylinders). Where coolant is leaking into the oil it is less likely that K\u2011Seal will be exposed to an atmosphere. Therefore, there is a reduced chance of K\u2011Seal making a successful repair.<\/p>\n
No. K\u2011Seal will only fix coolant leaks and cannot stop oil leaks.<\/p>\n
No. K\u2011Seal can only fix leaks in \u2018solid\u2019 parts of the cooling system including the head, head gasket, block, core plug, radiator and heater core.<\/p>\n
What you are seeing is not smoke but steam condensing as it exits the exhaust and hits cold air (just like when a kettle boils). The steam is the result of water entering the cylinder(s) due to a head gasket failure. The water boils in the cylinder and is expelled with the exhaust gases. You may also notice reduced engine performance, starting problems and fouled spark plugs.<\/p>\n
One cause of misting windshields is when there is a leak in the heater core. The heater core transfers heat from the coolant into warm air to heat up the cabin. If there is a coolant leak<\/a> in the core, then this contaminates the air entering the cabin. The moisture then condenses on the windshield cause the misting. You may also detect the smell of coolant\/antifreeze and, in extreme cases, you will notice damp patches in the footwells.<\/p>\n This indicates that you have water (coolant) leaking into the oil due to a head gasket problem. The water and oil combine and emulsify (a bit like mayonnaise) which results in the deposits around the filler cap.<\/p>\n K\u2011Seal can fix this type of leak but you need to get K\u2011Seal into the cooling system without it first being blown out by the gases blowing back from the cylinders. A couple of solutions are:<\/p>\n Even though there is pressure coming into the cooling system, there is almost always a small movement of coolant back across the crack as the pistons move up and down within the cylinder. K\u2011Seal is drawn into the crack and is then cured as the hot gases pass back through the crack.<\/p>\n Additional installation tips and information<\/a><\/p>\n Unlike other block sealers, K\u2011Seal is a simple \u2018pour & go\u2019 solution. Shake the bottle well and then add the entire contents to the cooling system where you would normally top up the coolant\/water.<\/p>\n 1 standard bottle of K\u2011Seal (236ml\/8floz) will treat cooling systems with a capacity up to 20 liters (this covers motorcycles up to light commercial vehicles). For larger cooling systems use our Heavy Duty (472ml\/16floz) size K\u2011Seal.<\/p>\n K\u2011Seal can be added to a cold or a hot engine. The important thing is that, once K\u2011Seal is in the coolant, you run the engine up to operating temperature to make sure that the coolant\/K\u2011Seal is flowing freely around the system.<\/p>\n K\u2011Seal must only be added to the coolant. Do not add K\u2011Seal to the oil.<\/p>\n It is not necessary to leave K\u2011Seal in the cooling system after the leak has been repaired although it will do no harm if you do so. Once K\u2011Seal makes a repair then that repair is permanent, regardless of whether you leave it in the system or not.<\/p>\n When K\u2011Seal repairs a leak then that repair is permanent.<\/p>\n Unfortunately, there are some problems that are beyond even K\u2011Seal\u2019s ability to seal leaks.\u00a0In the unlikely event this should be the case please get in touch with us and we can investigate why this did not work.<\/p>\n K\u2011Seal repairs a head gasket leak by filling the crack with ceramic microfibers that cure to make a permanent repair. If you decide to replace the head gasket at a later date the K\u2011Seal repair will be removed with the old gasket.<\/p>\n K\u2011Seal is suitable for use with all water cooled engines, regardless of size or fuel type.<\/p>\nI have a creamy deposit in the oil filler cap\/neck?
