Good To Know

Q: Does this head gasket need any sealant? A: Most head gaskets of this type install dry unless the service manual states otherwise, so follow the manufacturer's torque sequence and spec.

Q: Can I reuse an old head gasket? A: No, a head gasket is a single-use sealing part and should always be replaced once the cylinder head is removed.
