Expansion/Freeze Plug: Service and Repair
REMOVAL
Using a blunt tool such as a drift and a hammer, strike the bottom edge of the cup plug. With the cup plug rotated, grasp firmly with pliers or other suitable tool and remove plug.
CAUTION: Do not drive cup plug into the casting as restricted cooling and lubrication can result and cause serious engine problems.
INSTALLATION
1. Thoroughly clean inside of cup plug hole in cylinder block, or intake manifold. Be sure to remove old sealer.
2. Lightly coat inside of cup plug hole with Loctite Stud N' Bearing Mount or equivalent. Make certain the new plug is cleaned of all oil or grease.
3. Using proper drive plug, drive plug into hole so that the sharp edge of the plug is at least 0.5 mm (0.020 inch) inside the lead-in chamfer.
NOTE: It is not necessary to wait for curing of the sealant. The vehicle can be placed in service immediately.
