AIR CONDITIONING (A/C) COMPRESSOR REMOVAL/INSTALLATION - HYBRID
CAUTION:Electric A/C Compressor Oil only must be used as a refrigerant system lubricant for hybrid vehicles. Addition of any oil other than Electric A/C Compressor Oil to the hybrid vehicle refrigerant system will damage the electric Air Conditioning (A/C) compressor and contaminate the refrigerant system. See Refrigerant Oil Adding.
CAUTION:Service electric Air Conditioning (A/C) compressors are shipped with a small amount of electric compressor oil already installed which may not match the nominal amount required by the refrigerant system. Before installing a new service electric A/C compressor, the correct electric compressor oil level must be determined based on the amount of oil removed along with the oil electric A/C compressor. See Refrigerant Oil Adding. Failure to correctly match the electric compressor oil amount will result in damage to the electric A/C compressor and other refrigerant system components.
CAUTION:If installing a new Air Conditioning (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.
- 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. See Refrigerant System Filtering Following Air Conditioning (A/C) Compressor Installation.
- Install a new Thermostatic Expansion Valve (TXV), as directed by the A/C flushing or filtering procedure.
- 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.
1. With the vehicle in NEUTRAL, position it on a hoist. See Lifting.
2. Recover the refrigerant. See Air Conditioning (A/C) System Discharging And Recovery.
3. Depower the high-voltage traction battery system. See - Service and Repair
CAUTION:Failure to disconnect high-voltage cable connectors as instructed may result in damage to the connectors.
4. Release the clips and locking tabs and disconnect the interlock connector and the high-voltage cable connector at the Air Conditioning Compressor Module (ACCM).
- Press the locking clip in the white interlock connector and disengage the white connector before releasing the locking clip on the orange portion of the high-voltage connector. The white interlock connector will not come completely apart until the orange portion is released.
5. Detach the ACCM high-voltage cable connector pin-type retainer.
6. Remove the RH lower engine splash shield.
7. Remove the 2 Motor Electronics (M/E) coolant pump bolts and position the pump aside.
- To install, tighten to 20 Nm {2.0 kgf-m, 177 in-lbf}.
8. Remove the 2 A/C compressor fitting nuts and disconnect the fittings.
- Discard the O-ring seals and gasket seals.
- To install, tighten to 15 Nm {1.5 kgf-m, 133 in-lbf}.
9. Disconnect the A/C compressor electrical connector.
10. Remove the upper and lower front A/C compressor bolts.
- To install, tighten to 25 Nm {2.5 kgf-m, 18 ft-lbf}.
11. Completely loosen the lower rear A/C compressor bolt and remove the A/C compressor.
- To install, tighten to 25 Nm {2.5 kgf-m, 18 ft-lbf}.
CAUTION:Electric A/C Compressor Oil only must be used as a refrigerant system lubricant for hybrid vehicles. Addition of any oil other than Electric A/C Compressor Oil to the hybrid vehicle refrigerant system will damage the electric Air Conditioning (A/C) compressor and contaminate the refrigerant system. See Refrigerant Oil Adding.
12. To install, reverse the removal procedure.
- Install new gasket seals and O-ring seals.
- Add the correct amount of clean electric A/C compressor oil to the refrigerant system. See Refrigerant Oil Adding.
13. Evacuate, leak test and charge the refrigerant system. See Air Conditioning (A/C) System Evacuation And Charging.
