CAUTION:
If installing a new A/C compressor due to an internal failure of the old unit, carry out the following procedures to remove contamination from the A/C system. Failure to remove contamination from the A/C system, if present, will result in poor A/C performance and/or damage to the new A/C compressor and other components.
- If A/C flushing equipment is available, carry out flushing of the A/C system prior to installing a new A/C compressor. For additional information, refer to CLIMATE CONTROL SYSTEM - GENERAL INFORMATION AND DIAGNOSTICS article.
- If A/C flushing equipment is not available, carry out filtering of the A/C system after a new A/C compressor has been installed. For additional information, refer to CLIMATE CONTROL SYSTEM - GENERAL INFORMATION AND DIAGNOSTICS article.
- Install a new thermostatic expansion valve (TXV), as directed by the A/C flushing or filtering procedure.
- Install a new auxiliary TXV, as directed by the A/C flushing or filtering procedure.
- Install a new passenger zone valve. For additional information, refer to Passenger Zone Valve .
- Install a new battery zone valve. For additional information, refer to AUXILIARY CLIMATE CONTROL - HYBRID article.
- Install a new receiver/drier as directed by the A/C flushing or filtering procedure.
NOTE:
Installation of a new receiver/drier is not required when repairing the A/C system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the receiver/drier.
NOTE:
If installing a new A/C compressor, the A/C clutch disc and hub, A/C compressor pulley and A/C clutch field coil must be inspected and transferred from the old unit to the new unit if suitable for reuse.
- With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING AND LIFTING article.
- Recover the refrigerant. For additional information, refer to CLIMATE CONTROL SYSTEM - GENERAL INFORMATION AND DIAGNOSTICS article.
- Remove the RH lower engine splash shield.
- Release the tensioner and remove the drive belt from the A/C compressor pulley.
- Remove the A/C compressor manifold bolt and disconnect the manifold and tube assembly from the A/C compressor.
- Discard the O-ring seals.
- To install, tighten to 20 Nm (15 lb-ft).
- Disconnect the A/C clutch field coil electrical connector.
- Remove the 4 A/C compressor bolts and the A/C compressor.
- To install, tighten to 25 Nm (18 lb-ft).
- To install, reverse the removal procedure.
- If a new A/C compressor is to be installed, the clutch assembly must be transferred from the old unit to the new unit. For additional information, refer to Clutch and Clutch Field Coil - Hybrid .
- Install new O-ring seals.
- If not filtering the A/C system, lubricate the refrigerant system with the correct amount of clean PAG oil. For additional information, refer to CLIMATE CONTROL SYSTEM - GENERAL INFORMATION AND DIAGNOSTICS article.
- Evacuate, leak test and charge the refrigerant system. For additional information, refer to CLIMATE CONTROL SYSTEM - GENERAL INFORMATION AND DIAGNOSTICS article.
NOTE:
Service A/C compressors are shipped without PAG oil installed.
NOTE:
If installing a new A/C compressor, transfer the shipping caps from the new A/C compressor to the old A/C compressor after the refrigerant oil has been measured.
