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 Vehicle Lifting.

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

3. Remove the A/C (Air Conditioning) belt. REFER to Air Conditioning (AC) Compressor Belt - 2.0L GDI .

4. Remove the rear A/C (Air Conditioning) shield bolt.
- To install, tighten to 25 Nm (18 lb-ft).





5. Remove the 2 A/C (Air Conditioning) compressor fitting nuts and disconnect the fitting.

- Discard the O-ring seals and gasket seals.
- To install, tighten to 20 Nm (177 lb-in).





6. Disconnect the A/C (Air Conditioning) clutch field coil electrical connector.

Installation

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.

1. To install, reverse the removal procedure.

- Install new O-ring seals and gasket seals.

- If filtering of the refrigerant system is not to be carried out, add the correct amount of clean PAG (Polyalkylene Glycol) oil to the refrigerant system. REFER to Refrigerant Oil Adding .

2. If filtering of the refrigerant 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 .
