Description: The cylinder head gasket is a key component of the engine. It is compressed between the engine block and the cylinder head. The cylinder head gasket seals the internal combustion process, ensuring maximum compression is achieved, and also prevents the coolant and oil from mixing as the two fluids move from the engine block to the cylinder head. There will come a time when your head gasket will leak or blow. Always remember that when a head gasket fails, you should install a new head gasket immediately. Be sure to replace your engine gaskets with replacement head gaskets as soon as they start giving you trouble.
