An engine cylinder head gasket sits between the head and the block. It holds combustion pressure inside the cylinders. It also keeps the coolant and oil passages that run through that joint separate from each other and from the combustion chambers.
Signs that a head gasket may need replacing include unexplained coolant loss, white exhaust smoke, overheating, coolant mixing with oil, or low compression. These symptoms can have other causes, so diagnose the engine before replacing parts. When installing, follow the vehicle service information for surface preparation, torque sequence and the correct fasteners, including whether the original head bolts may be reused.
