15. Remove the oil pan.




16. Remove the oil pan gasket.
17. Discard the oil pan gasket.
18. Clean all sealing surfaces on the engine and the oil pan. Refer to Oil Pan Cleaning and Inspection.

Installation Procedure





Notice: Any time the transmission and the engine oil pan are off of the engine at the same time, install the transmission before the oil pan. This is to allow for the proper oil pan alignment. Failure to achieve the correct oil pan alignment can result in transmission failure.

1. Apply a 5 mm (0.197 in) wide and 25 mm (1.0 in) long bead of adhesive to both the right and left sides of the engine front cover to engine block junction at the oil pan sealing surfaces. Refer to Sealers, Adhesives, and Lubricants for the correct part number.




2. Apply a 5 mm (0.197 in) wide and 25 mm (1.0 in) long bead of adhesive to both the right and left sides of the crankshaft rear oil seal housing to engine block junction at the oil pan sealing surfaces. Refer to Sealers, Adhesives, and Lubricants for the correct part number.





Important: Always install a NEW oil pan gasket.

The oil pan gasket and oil pan must be installed and the fasteners tightened while the adhesive is still wet to the touch.

3. Install the NEW oil pan gasket into the groove in the oil pan.





Important: The oil pan alignment must always be flush or forward no more than 0.3 mm (0.011 in) from the rear face of the engine block.

4. Install the oil pan onto the engine block.
Press the oil pan gasket into the grooves of the engine front cover and crankshaft rear oil seal housing.
5. Slide the oil pan back against a suitable straight edge.




6. Install the oil pan bolts and nuts, but do not tighten.
7. Measure the pan-to-transmission housing clearance using a feeler gage and a straight edge.
Use a feeler gage to check the clearance between the oil pan-to-transmission housing measurement points. If the clearance exceeds 0.3 mm (0.011 in) at any of the 3 oil pan-to-transmission housing measurement points (1), then repeat the step until the oil pan-to-transmission housing clearance is within the specification. The oil pan must always be forward of the rear face of the engine block.





Notice: Refer to Fastener Notice.

8. Tighten the oil pan bolts and nuts in sequence (1-12).

Tighten the oil pan bolts to 25 N.m (18 lb ft).

9. Measure the clearance between the 3 oil pan-to-transmission housing measurement points in order to ensure proper alignment.




10. Install a NEW oil pan drain plug seal (O-ring) onto the oil pan drain plug.
11. Install the oil pan drain plug into the oil pan.

Tighten the oil pan drain plug to 25 N.m (18 lb ft).




12. Install the NEW engine oil level sensor, if applicable.

Tighten the engine oil level sensor to 13 N.m (115 lb in).




13. Install the transmission to oil pan bolts.

Tighten the bolts to 47 N.m (35 lb ft).




14. Install the transmission cover.

Tighten the transmission cover bolts to 12 N.m (106 lb in).




15. Install the access plugs for the oil pan rear nuts.
16. Install the starter motor.




17. Install the bolt holding the bracket for the starter wiring harness and the transmission cooler pipes.

Tighten the bracket bolt to 9 N.m (80 lb in).

18. Install the CKP sensor wiring harness in the retainer.
19. Install the oil filter adapter.
20. Install the oil filter and the oil pan drain plug.
21. If equipped with AWD, install the front differential carrier.
22. Lower the vehicle.
23. Fill the crankcase with engine oil.
24. Connect the battery negative cable.
