^ J 39400-A Halogen Leak Detector

Removal Procedure

1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging.
2. Remove the A/C belt. Refer to Drive Belt Replacement - Air Conditioning in Engine Mechanical - 8.1L.
3. Remove the right front tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
4. Remove the right wheel house panel. Refer to Wheelhouse Panel Replacement in Body Front End.
5. Remove the bolt from A/C compressor hose assembly.
6. Remove the A/C compressor hose assembly from the A/C compressor.
7. Discard the sealing washers. Cap all of the openings.
8. Disconnect the electrical connectors from the A/C compressor.






9. Remove the 3 A/C compressor mounting bolts. The lower right bolt will stay with the compressor due to a lack of clearance.
10. Remove the A/C compressor from the bracket through the fender well.
11. If replacing the A/C compressor, drain and measure as much of the oil as possible from the removed compressor.
A. Drain the oil from both the suction and discharge ports of the removed A/C compressor into a clean container.

C. Measure and record the amount of oil drained from the removed A/C compressor. This measurement will be used during installation of the replacement A/C compressor.
D. Properly discard the used PAG oil.

Installation Procedure

1. Add the proper amount of PAG oil to the compressor crankcase. Refer to Refrigerant System Capacities.

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 A/C compressor drain plug.

Tighten

^ Tighten the drain plug to 20 N.m (15 lb. ft.).

Important: Insert the mounting bolt into the lower right mounting bracket before installing the A/C compressor.

3. Install the A/C compressor to the mounting bracket.
