What is a head gasket sealer?

A head gasket is a thin steel/ cork gasket located between the cylinder and main block of your engine. Its function is to prevent the coolant liquid from mixing with the lubricating oil.

A head gasket sealant can be poured into your radiator cap, where it enters the coolant system and discovers the leak. By sealing the leak, you can continue to drive your car without the need for heavy mechanical repairs.
