Lincoln Aviator: Climate Control System - General Information / Removal and Installation - Air Conditioning (A/C) Compressor - 3.0L EcoBoost

Removal

NOTICE: 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.

NOTICE: 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: 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.
