Good To Know

Q: Do I need to apply sealant to this head gasket? A: Most head gaskets of this type install dry unless the service manual says otherwise, so follow the factory torque sequence and specs.

Q: Is this gasket reusable if the head comes off again? A: No, a head gasket is a single-use item and should be replaced each time the cylinder head is removed.
