Removal

1. Drain the engine coolant. Cooling System
2. Loosen the clamps and remove the charge air cooler (CAC) intake pipe.







3. Cut the oil cooler-to-EGR cooler hose at an angle where shown.
4. Remove the 2 bolts and the EGR cooler supply port housing cover.
5. Remove the EGR cooler supply port housing and the part of the oil cooler-to-EGR cooler hose that is still attached.







6. Twist and pull the oil cooler-to-EGR cooler hose to remove it from the EGR cooler tube.







7. Rotate the oil cooler-to-EGR cooler hose 90 degrees (1/4-turn) and remove it from the EGR cooler supply port housing.

Installation

1. Clean and inspect the EGR cooler supply port housing O-ring seals. Install new O-ring seals if necessary.







2. Lubricate the inside of the new oil cooler-to-EGR cooler hose with clean engine coolant and slide it onto the EGR cooler tube far enough so it will not interfere with the installation of the EGR cooler supply port.
- Make sure the dual index marks (flat edge) on the hose are facing up.

3. Lubricate the EGR cooler supply port housing O-ring seals with clean engine coolant and position the EGR cooler supply port on the engine.








4. NOTE: Use a commercially available Torx bit, such as Matco� BTX3OB, or equivalent, and a torque adapter to tighten the EGR cooler supply port housing cover bolts.

Position the EGR cooler supply port housing cover and install the 2 bolts.
- Calculate the correct torque wrench setting for the following torque with any adapters used.
- Tighten to 10 Nm (89 lb-in).







5. Slide the oil cooler-to-EGR cooler hose onto the EGR cooler supply port housing and rotate it 90 degrees (1/4-turn) until it locks in place.
6. Install the CAC intake pipe and tighten the clamps.
- Tighten to 12 Nm (9 lb-ft).
