Engine Oil Pump - Installation

INSTALLATION

Special Tools:










1. If removed, install the plunger (2), spring (3) and oil pressure regulator cap (5) with a new O-ring seal (4) to the oil pump (1).





2. Install a new oil pump gasket (1) to the oil pump. Roll the three gasket retaining tabs over the pump flange at the indicated locations.





3. Install a new oil filter housing seal (2) onto the oil filter housing.
4. Clean the cylinder block and bedplate mating surfaces with isopropyl alcohol in preparation for sealant application.

CAUTION: Engine assembly requires the use of a unique sealant that is compatible with engine oil. Using a sealant other than Mopar(R) Engine RTV GEN II may result in engine fluid leakage.

CAUTION: Following the application of Mopar(R) Engine RTV GEN II to the gasket surfaces, the components must be assembled within 10 minutes and the attaching fasteners must be tightened to specification within the next 10 minutes. Prolonged exposure to the air prior to assembly may result in engine fluid leakage.

5. Apply a 2 to 3 mm wide bead of Mopar(R) Engine RTV GEN II sealant (1) to the two cylinder block to bedplate T-joints as shown.





6. Install the oil pump and gasket (1) with seven bolts (2) hand tight.





7. Attach the (8225) (2) to the oil pan mounting flange using the oil pan bolts (1). Tighten the bolts to 9 Nm (80 in. lbs.).

NOTE: Make sure that the "2.7L" stamped on the alignment fixture is facing the cylinder block (flat side of tools against oil pan mounting flange).






8. Allow the oil pump to center itself on the crankshaft and position the oil pump so that the distance between the oil pump flange and the alignment fixture is equal on both sides (1).

NOTE: Do not force the oil pump flange down against the alignment fixture.

9. While maintaining this alignment, tighten the seven bolts in the sequence shown to 10 Nm (89 in. lbs.).





10. Install new O-ring seals (1 and 2) on the oil filter housing to oil pump bolt.





11. Install the oil filter housing to oil pump bolt (1) and tighten to 45 Nm (33 ft. lbs.).





12. Install the lower oil cooler housing heatshield (2) with four bolts tightened to 3 Nm (26 in. lbs.).






CAUTION: When the timing belt is removed and the cylinder head is still installed, DO NOT rotate the camshaft or crankshaft without first locating the proper crankshaft position. Failure to do so will result in valve and/or piston damage.

13. If removed, install the front crankshaft oil seal (1) Rear Crankshaft Oil Seal - Installation.





14. Install the timing belt and sprockets Sprocket(s) - Installation.
15. Install the crankshaft position (CKP) sensor (3) Crankshaft Position Sensor - Installation.






NOTE: The oil pressure switch has a lock patch on the threads and if removed can not be reinstalled.

16. If removed, install a new oil pressure switch (2) Oil Pressure Switch - Installation.





17. Install the oil pump pick-up (1) and the oil pan Oil Pump Pick-up - Installation.






NOTE: A new engine oil pump must be primed with oil before engine operation.

18. If installing a new engine oil pump, remove the oil filter and prime the new pump through the oil filter housing with approximately 0.5 liter (0.5 quart) of engine oil. Direct the oil into the side port (filter inlet) (1) as shown and not the center port (filter outlet) Engine Oil Filter - Removal.
19. If removed, install the oil filter and fill the engine crankcase with the proper oil to the correct level Service and Repair.
20. Connect the negative battery cable and tighten nut to 5 Nm (45 in. lbs.).
21. Fill the cooling system Service and Repair.
22. Start and run the engine until it reaches normal operating temperature. Check cooling system for correct fluid level Service and Repair.

NOTE: The Cam/Crank Variation Relearn procedure must be performed using the scan tool anytime there has been a repair/replacement made to a powertrain system, for example: flywheel, valvetrain, camshaft and/or crankshaft sensors or components PCM/ECM Reprogramming .
