Air Conditioning (A/C) Compressor: Removal
WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
During the removal of components, cap, tape or otherwise appropriately protect all openings to prevent the ingress of dirt or other contamination. Remove protective materials prior to installation.
NOTE:
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.
- If A/C flushing equipment is not available, replace all contaminated components after a new A/C compressor has been installed.
- Install a new Thermostatic Expansion Valve (TXV) as directed by the A/C flushing.
- Install a new receiver drier element as directed by the A/C flushing.
NOTE:
Installation of a new receiver drier element 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 element.
NOTE:
A new A/C compressor may come equipped with an A/C clutch disc and hub, A/C compressor pulley and A/C clutch field coil already installed. If these components are not pre-installed, it will be necessary to transfer these parts from the old A/C compressor to the new compressor prior to installation of the A/C compressor if suitable for reuse.
NOTE:
Removal steps in this procedure may contain installation details.
- Recover the refrigerant. Refer to: Air Conditioning (A/C) System Recovery, Evacuation and Charging .
- Remove the A/C compressor belt. Refer to: Air Conditioning (A/C) Compressor Belt 2.0L EcoBoost (177kW/240PS) - MI4 . Refer to: Air Conditioning (A/C) Compressor Belt 2.3L EcoBoost (201kW/273PS) .
