Signs a head gasket may need replacing include coolant loss with no visible leak, white exhaust smoke, overheating, milky engine oil or bubbles in the coolant reservoir. These symptoms can have other causes, so diagnose the engine before replacing parts; if a failed head gasket is the cause, this part replaces it. Consult the vehicle service information for the head bolt procedure and whether the original bolts may be reused.
