Good To Know

Q: Do I need to replace head bolts when installing this gasket? A: Many manufacturers call for new torque-to-yield head bolts during a head gasket job, so check your service manual for the 1503 engine before reassembly.

Q: Can this gasket be reused if the head is removed again? A: Head gaskets are single-use sealing components and should be replaced any time the cylinder head is lifted, so keep a spare on hand for future work.

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