REMOVAL & INSTALLATION

- Thoroughly clean the inside of the plug hole in the cylinder block or head. Be sure to remove any old sealer.
- Lightly coat the inside of the plug hole with Loctite® or an equivalent. Make certain the new plug is clean before insertion.
- Using a drive tool, insert the plug into the hole so that the sharp edge of the plug is at least 0.02 in. (0.5mm) inside the chamfer.
