Specs At A Glance

Good To Know

Q: Do I need to replace head bolts when installing this gasket? A: Many torque-to-yield head bolts are single-use, so check the service manual for the 1800 engine and replace them if specified to ensure a proper seal.

Q: Can I install this gasket without machining the head? A: The head and block surfaces should be clean and flat, so have them checked if the engine overheated, since a warped surface will cause the new gasket to fail.

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