Good To Know

Q: Does this gasket require any sealant during installation? A: Many head gaskets are installed dry, but always follow the service manual for your specific model. Check mating surfaces for flatness and cleanliness before assembly.

Q: Should the cylinder head bolts be replaced at the same time? A: Torque-to-yield head bolts should not be reused once stretched. If your service manual specifies new bolts, replace them along with this head gasket.

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