A cylinder head gasket seals the joint between the cylinder head and engine block, containing combustion pressure while sealing the coolant and oil passages that cross that joint. If a failed head gasket is behind your symptoms — coolant loss, overheating, white exhaust smoke, or oil and coolant mixing — this replaces it; diagnose the cause before replacing. Country of origin: Germany.
