How to Install a Head Gasket. The head gasket is found between the engine block and the cylinder head or heads in a V-type engine. The gasket functions as a seal that prevents the combustion process from leaking into the coolant passages that surround each cylinder.In many cases it seals oil passages from coolant passages so the fluids do not mix.. Drain all of the oil and coolant from your engine. Remove the parts that are on top of the head gasket. Refer to your car's service manual for specifics, but in most cases this involves removing the exhaust manifold, the intake manifold, valve cover and drive belts.
