Installation Procedure

You need a working oil pump to pump the oil around the engine. If the oil is not being pumped through, the oil pump has failed or there is a blockage in the lubrication system.

Most likely the oil pump has failed and needs to be replaced.

You have to remove the engine front cover (over timing chain) and remove the oil pan to get the oil pump in and out. You don't have to remove the heads, however.

REMOVAL & INSTALLATION

Gasoline Engines
See Figures 1 and 2

1. Follow the service procedures under Oil Pan Removal and remove the oil pan assembly.
2. Remove the oil pump retainer bolts and remove the oil pump.

To install:

1. Prime the oil pump with clean engine oil by filling either the inlet or outlet port with clean engine oil.
2. Rotate the pump shaft to distribute the oil within the pump body. Install the pump and tighten the mounting bolts to 14-21 ft. lbs. on 2.0L and 2.3L engines; 6-10 ft. lbs. on 2.8L and 2.9L engines or 13-15 ft. lbs. on 4.0L engines.

Do not force the oil pump if it does not seat readily. The oil pump driveshaft may be misaligned with the distributor shaft assembly. To align, rotate the intermediate driveshaft into a new position.

1. Install the oil pan as previously described. The oil pumps are not serviceable. If defective, they must be replaced.
