Removal & Installation

WARNING: This page is about a different car, the 2010 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: If installing a new air conditioning (A/C) compressor due to an internal failure of the old unit, the following procedures must be carried out 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 the flushing of the A/C system prior to installing a new A/C compressor. For additional information, refer to CLIMATE CONTROL SYSTEM - GENERAL INFORMATION & 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 & DIAGNOSTICS article.
  • Install a new evaporator core orifice as directed by the A/C flushing or filtering procedure.
  • Install a new suction accumulator as directed by the A/C flushing or filtering procedure.
NOTE: Installation of a new suction accumulator is not required when repairing the A/C system, except when there is physical evidence of contamination from a failed A/C compressor or damage to the suction accumulator. Damage to the suction accumulator includes leaks in the suction accumulator, physical damage to the suction accumulator shell or desiccant, or moisture contamination. Moisture contamination results only from a complete loss of refrigerant and equalization of the refrigerant system pressure with atmospheric pressure for a period longer than one hour. If even a slight amount of positive refrigerant pressure is present in the system before repairs are carried out, a new suction accumulator should not be installed.
  1. If flushing of the A/C system has not been carried out, recover the refrigerant. For additional information, refer to CLIMATE CONTROL SYSTEM - GENERAL INFORMATION & DIAGNOSTICS article.
  2. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING & LIFTING article.
  3. Remove the drive belt from the A/C compressor pulley.
  4. Disconnect the field coil electrical connector.
  5. Remove the 2 A/C compressor fitting nuts and disconnect the fittings.
    • Discard the gasket seals and O-ring seals.
    • To install, tighten to 15 Nm (11 lb-ft).
    6. NOTE: The upper rear and lower rear A/C compressor studs must be removed with the A/C compressor.
  6. Remove the 3 A/C compressor studs.
    • To install, tighten to 25 Nm (18 lb-ft).
  7. Remove the A/C compressor.
  8. To install, reverse the removal procedure.
  9. If filtering of the refrigerant system is not to be carried out, evacuate, charge and leak test the refrigerant system. For additional information, refer to CLIMATE CONTROL SYSTEM - GENERAL INFORMATION & DIAGNOSTICS article.
