Compressor HVAC: Service and Repair
Air Conditioning (A/C) Compressor - Hybrid
Removal and Installation
NOTICE: Motorcraft(R) Electric A/C Compressor Oil only must be used as a refrigerant system lubricant for hybrid vehicles. Addition of any oil other than Motorcraft(R) 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. Refer to the Refrigerant Oil Adding procedure in Climate Control System - General Information and Diagnostics Refrigerant Oil Adding.
NOTICE: 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 old electric A/C compressor. Refer to the Refrigerant Oil Adding procedure in Climate Control System - General Information and Diagnostics 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.
NOTICE: 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. For additional information, refer to Climate Control System - General Information and Diagnostics Air Conditioning (A/C) System Flushing.
- 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 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. For additional information, refer to Jacking and Lifting Service and Repair.
2. Recover the refrigerant. For additional information, refer to Climate Control System - General Information and Diagnostics Air Conditioning (A/C) System Recovery, Evacuation and Charging.
3. Depower the high-voltage traction battery system. For additional information, refer to High Voltage Traction Battery Service and Repair.
4. NOTICE: Failure to disconnect high-voltage cable connectors as instructed may result in damage to the connectors.
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 (177 lb-in).
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 (133 lb-in).
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 (18 lb-ft).
11. Completely loosen the lower rear A/C compressor bolt and remove the A/C compressor.
- To install, tighten to 25 Nm (18 lb-ft).
12. NOTICE: Motorcraft(R) Electric A/C Compressor Oil only must be used as a refrigerant system lubricant for hybrid vehicles. Addition of any oil other than Motorcraft(R) 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. Refer to the Refrigerant Oil Adding procedure in Climate Control System - General Information and Diagnostics Refrigerant Oil Adding.
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. For additional information, refer to the Refrigerant Oil Adding procedure in Climate Control System - General Information and Diagnostics Refrigerant Oil Adding.
13. Evacuate, leak test and charge the refrigerant system. For additional information, refer to Climate Control System - General Information and Diagnostics Air Conditioning (A/C) System Recovery, Evacuation and Charging.
