How to Replace a Head Gasket in a BMW


The head gasket is a seal that protects the car’s cylinders by preventing coolant leakage and by keeping the coolant and oil from mixing. Inside a BMW, the head gasket sits underneath the cylinder head. If the BMW’s engine tends to overheat, it can damage the head gasket. When replacing a damaged gasket, be prepared to drain your coolant system and undertake a major operation in removing all of the engine’s components just to access the gasket.

Replacement gasket head, Heavy-duty socket wrench, Needle-nose pliers, Adjustable wrench, Drain pan, Commercial coolant mixture, Water, Putty knife
