Important: Flush the oil cooler and replace the oil filter in order to prevent premature engine wear if the following conditions exist:

1. Remove the engine oil cooler line mounting bracket to the radiator lower mounting panel.
2. Remove the cooler line flare nut from the engine oil cooler.



3. Remove the cooler lines (2) from the engine oil cooler (1).
4. Remove the engine oil cooler mounting bolts.
5. Remove the engine oil cooler (1) from the mounting bracket (3).

1. Connect the engine oil cooler (1) to the mounting bracket (3).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

2. Install the engine oil cooler mounting nuts.

Tighten
Tighten the engine oil cooler mounting nut to 13 N·m (115 lb in).

3. Connect the cooler lines (2) to the engine oil cooler (1).

Tighten
Tighten the engine oil cooler line flare nut to 24 N·m (18 lb ft).




4. Install the engine oil cooler line mounting bracket to the radiator lower mounting panel.
5. Refill the engine oil to the correct level. Refer to Cooling System Draining and Filling .
6. Start the engine.
7. Inspect the system for leaks.
