Good To Know

Q: Are new head bolts needed with this gasket? A: Many 1800 engine head bolts are torque-to-yield and should not be reused. Check the service manual for the torque sequence and bolt replacement guidance.

Q: Can this gasket be reused after removal? A: A head gasket is a single-use item once it has been compressed and heat cycled. Install a fresh gasket whenever the cylinder head comes off.
