Good To Know

Q: Should head bolts be replaced with the gasket? A: Many torque-to-yield head bolts are single-use, so check your service manual and replace them if specified when installing this gasket.

Q: Is sealant required on this gasket? A: Most modern multi-layer head gaskets go on dry, so follow the service manual rather than adding sealant that can interfere with sealing.

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