25. NOTE: The heavy duty Engine Support Bar (303-F070) must be used with the draw screws from the light duty Engine Support Bar (303-F072). This will provide enough clearance between the SC and the Engine Support Bar, and enough clearance between the draw screw and the vehicle hood.

Install the Engine Support Bars.
- Remove the LH and RH engine support insulator nuts.

- Using the Engine Support Bars, raise the engine.





26. Remove the nut and disconnect the B+ wire terminal from the generator.

30. Remove the stud bolt, 2 bolts and the generator.

31. Disconnect the coolant hose from the oil filter adapter.

32. NOTICE: If metal or aluminum material is present in the oil cooler, mechanical concerns exist. Failure to correct these concerns may cause engine failure.

Remove the 6 bolts and the oil cooler.
- Discard the gaskets.

- Inspect the oil cooler.

33. Drain the engine oil.
- Tighten the drain plug to 26 Nm (19 lb-ft).

34. Remove and discard the engine oil filter.

35. Remove the 3 coolant tube assembly bolts.

36. Disconnect the Engine Oil Pressure (EOP) switch electrical connector and the 2 wiring harness pin-type retainers.

37. Remove the 8 bolts and the oil filter adapter.
- Discard the gasket.

38. Remove the 2 oil pan-to-engine front cover bolts and the 2 oil pan-to-engine front cover stud bolts.

39. Remove the 4 bolts and the coolant pump.
- Discard the gasket.

40. Remove the 16 bolts and the engine front cover.
- Remove and discard the engine front cover gaskets.

- NOTICE: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of old sealant.

Clean the mating surfaces with silicone gasket remover and metal surface prep. Follow the directions on the packaging.

- Inspect the mating surfaces.





Installation

1. NOTE: If the engine front cover is not secured within 4 minutes, the sealant must be removed and the sealing area cleaned with metal surface prep. Allow to dry until there is no sign of wetness or 4 minutes, whichever is longer. Failure to follow this procedure can result in future oil leakage.

Apply silicone gasket and sealant in the locations shown.





2. Using new gaskets, install the engine front cover and the 16 bolts. Tighten the bolts in the sequence shown:

- Bolts 1 through 14 to 25 Nm (18 lb-ft).

3. Install the 2 oil pan-to-engine front cover bolts and the 2 oil pan-to-engine front cover stud bolts.
- Tighten to 25 Nm (18 lb-ft).

4. Using a new gasket, install the coolant pump and the 4 bolts.
- Tighten to 25 Nm (18 lb-ft).

5. NOTE: Clean and inspect the sealing surfaces with metal surface prep. Follow the directions on the packaging.

Using a new gasket, install the oil filter adapter and the 8 bolts.

- Tighten in the sequence shown:
- Bolts 1 through 6 to 25 Nm (18 lb-ft).

- Bolts 7 and 8 to 50 Nm (37 lb-ft).





6. Connect the EOP switch electrical connector and the 2 wiring harness pin-type retainers.
