The head gasket forms a seal between the engine block and the cylinder head. This means your head gasket has to seal both extremely hot, high-pressure combustion gases as well as engine coolant which can be anywhere from cold ambient temperatures to the normal operating temperature of your engine.
Fitment Applications
For Isuzu FVZ & FVR model trucks with the 6HK1 engine.
In an internal combustion engine, a head gasket provides the seal between the engine block and cylinder head (s). Its purpose is to seal the combustion gases within the cylinders and to avoid coolant or engine oil leaking into the cylinders. Leaks in the head gasket can cause poor engine running and/or overheating.
