Dakota 2WD V8-5.9L VIN Z (1998)
Expansion/Freeze Plug: Service and Repair
Engine core plugs have been pressed into the oil galleries behind the camshaft thrust plate. This will reduce internal leakage and help maintain higher
oil pressure at idle
REMOVAL
1. Using a blunt tool such as a drift or a screwdriver and a hammer, strike the bottom edge of the cup plug.
2. With the cup plug rotated, grasp firmly with pliers or other suitable tool and remove plug.
INSTALLATION
Thoroughly clean inside of cup plug hole in cylinder block or head. Be sure to remove old sealer.
Be certain the new plug is cleaned of all oil or grease.
1. Coat edges of plug and core hole with Mopar Gasket Maker, or equivalent.
CAUTION: DO NOT drive cup plug into the casting, as restricted coolant flow can result and cause serious engine problems.
2. Using proper plug drive, drive cup plug into hole. The sharp edge of the plug should be at least 0.50 mm (0.020 inch) inside the lead-in chamfer.
3. It is not necessary to wait for curing of the sealant. The cooling system can be filled and the vehicle placed in service immediately.
