Good To Know

Q: Should I replace the head gasket if I remove the cylinder head? A: Yes, a head gasket is generally a single-use item, so fitting a fresh gasket while the head is off helps prevent leaks and compression loss.

Q: Does this gasket require any sealant during installation? A: Many head gaskets install dry, so follow your service manual and torque the head bolts to the specified sequence and value.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
