ENGINE CORE AND OIL GALLERY PLUGS





Using a blunt tool such as a drift (2) and a hammer, strike the bottom edge of the cup plug (3). With the cup plug rotated, grasp firmly with pliers (1) or other suitable tool and remove plug.

CAUTION: Do not drive cup plug into the casting as restricted cooling can result and cause serious engine problems.

Thoroughly clean the inside of the cup plug hole in the cylinder block or head. Be sure to remove any old sealer. Lightly coat the inside of the cup plug hole with Mopar(R) Stud and Bearing Mount. Make certain the new plug is cleaned of all oil or grease. Using the proper drive plug, drive the plug into the hole so that the sharp edge of the plug is at least 0.020 in. (0.5 mm) inside the lead-in chamfer.

It is not necessary to wait for the curing of the sealant. The cooling system can be refilled and the vehicle placed in service immediately.
