Removal

NOTICE: If installing a new A/C (Air Conditioning) compressor due to an internal failure of the old unit, carry out the following procedures to remove contamination from the A/C (Air Conditioning) system. Failure to remove contamination will result in poor A/C (Air Conditioning) performance and/or damage to the A/C (Air Conditioning) system components.
- If A/C (Air Conditioning) flushing equipment is available, carry out flushing of the A/C (Air Conditioning) system prior to installing a new A/C (Air Conditioning) compressor. REFER to Air Conditioning (AC) System Flushing .
- If A/C (Air Conditioning) flushing equipment is not available, carry out filtering of the A/C (Air Conditioning) system after a new A/C (Air Conditioning) compressor has been installed. REFER to Refrigerant System Filtering Following Air Conditioning (AC) Compressor Installation .
- Install a new TXV (Thermostatic Expansion Valve), as directed by the A/C (Air Conditioning) flushing or filtering procedure.
- Install a new receiver/drier desiccant cartridge as directed by the A/C (Air Conditioning) flushing or filtering procedure.

NOTE: Installation of a new receiver/drier desiccant cartridge is not required when installing a new A/C (Air Conditioning) compressor, except when there is physical evidence of a failed A/C (Air Conditioning) compressor, or damage to the receiver/drier desiccant cartridge.

1. With the vehicle in NEUTRAL, position it on a hoist. REFER to Jacking and Lifting .

2. If flushing of the A/C (Air Conditioning) system has not been carried out, recover the refrigerant. REFER to Air Conditioning (AC) System Recovery, Evacuation, and Charging .



3. Remove the drive belt from the A/C (Air Conditioning) compressor pulley.

4. Disconnect the field coil electrical connector and detach wiring harness from the A/C compressor and position aside.

5. Remove the rear A/C (Air Conditioning) compressor bolt.



6. Remove the A/C (Air Conditioning) compressor suction fitting bolt and disconnect the fitting.

- Discard the O-ring seal.

7. Remove the A/C (Air Conditioning) compressor discharge fitting bolt and disconnect the fitting.

- Discard the O-ring seal.

8. Remove the A/C (Air Conditioning) compressor nut and stud.

9. Remove the upper A/C (Air Conditioning) compressor bolt.

10. Remove the A/C (Air Conditioning) compressor.

Installation

1. NOTE: The service A/C (Air Conditioning) compressor for this vehicle is shipped from the factory with PAG (Polyalkylene Glycol) oil installed. The refrigerant oil adding procedure specified for this vehicle must be followed to avoid installing excessive PAG (Polyalkylene Glycol) oil in the refrigerant system.
If filtering of the A/C (Air Conditioning) system is not to be carried out, lubricate the refrigerant system with the correct amount of clean PAG (Polyalkylene Glycol) oil. REFER to Refrigerant Oil Adding

2. Install the compressor and upper A/C (Air Conditioning) compressor bolt, but do not tighten.

3. Install the A/C (Air Conditioning) compressor stud.
- Tighten to 9 Nm (80 lb-in).

4. Connect the A/C (Air Conditioning) compressor discharge fitting and install the A/C (Air Conditioning) compressor discharge fitting bolt.

- Install a new O-ring seal lubricated in clean PAG (Polyalkylene Glycol) oil.
- Tighten to 15 Nm (133 lb-in).

5. Connect the A/C (Air Conditioning) compressor suction fitting and install the A/C (Air Conditioning) compressor suction fitting bolt.

- Install a new O-ring seal lubricated in clean PAG (Polyalkylene Glycol) oil.
- Tighten to 15 Nm (133 lb-in).

6. Tighten the A/C (Air Conditioning) compressor bolt and nut.
- Tighten to 25 Nm (18 lb-ft).



7. Install the rear A/C (Air Conditioning) compressor bolt.
- Tighten to 25 Nm (18 lb-ft).

8. Position back and attach wiring harness to the A/C (Air Conditioning) compressor and connect the field coil connector.

9. Install the drive belt.

10. If filtering of the A/C (Air Conditioning) system is not to be carried out, evacuate, leak test and charge the refrigerant system. REFER to Air Conditioning (AC) System Recovery, Evacuation, and Charging .
