A/C compressor1. Drain old A/C compressor. With drain plug removed and ports uncapped, rotate shaft to remove A/C compressor oil and measure the amount of oil captured. 2. Drain new A/C compressor into a clean vessel. With drain plug removed and ports uncapped, rotate shaft to remove oil. Then add back a quantity of the new oil that is identical to the quantity of oil removed from the old A/C compressor. However, if this quantity is less than 30ml, then make it up to 30ml.

PRINCIPLES OF OPERATION

For a detailed description of the Climate Control System and operation, refer to the relevant Description and Operation instructions. Refer to Air Distribution and Filtering or Refer to Air Distribution and Filtering . Refer to Heating and Ventilation . Refer to Auxiliary Heater and Refer to Air Conditioning . Refer to Auxiliary Climate Control and Refer to Control Components .

INSPECTION AND VERIFICATION

CAUTIONDiagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
  1. Verify the customer concern.
  2. Visually inspect for obvious signs of mechanical or electrical damage. VISUAL INSPECTION Mechanical Electrical Coolant level Air vents (contaminated/blocked) Auxiliary drive belt condition and tension Air conditioning compressor Fuses Harnesses Electrical connector(s) Relays Control module(s) Control panel(s) Air conditioning compressor
  3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  4. If the cause is not visually evident, check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

DTC INDEX

For a list of Diagnostic Trouble Codes (DTCs) that could be logged on this vehicle, please refer to Diagnostic Trouble Code (DTC) Index - DTC: Module Name: Climate Control Module and Diagnostic Trouble Code (DTC) Index - DTC: Module Name: Rear Climate Control Module .

  1. Refrigerant recovery.
  2. See figure NOTE: Some variation in the illustrations may occur, but the essential information is always correct. Remove the dust covers from the high and low pressure connections.
  3. Connect the high and low pressure lines to the appropriate connections.
  4. Following the manufacturer's instructions, recover the refrigerant from the A/C system. Measure and record the quantity of refrigerant oil recovered from the system.
  5. Disconnect the high and low pressure connections.
  6. Evacuation.
  7. Connect the high and low pressure lines to the appropriate connections.
  8. Following the manufacturer's instructions, evacuate the A/C system.
  9. Refer to «Receiver Drier - 5.0L NA V8 - AJ133»(/land-rover/range-rover/l322-2009-2012/remont/automatic-hvac-system/#air-conditioning) and «Receiver Drier - 5.0L SC V8 - AJ133»(/land-rover/range-rover/l322-2009-2012/remont/automatic-hvac-system/#air-conditioning) .
  10. Recharging
  11. Ensure the correct amount of oil is added to the A/C system before or during recharging.
  12. Recharge the A/C system to the correct specification. See «Specifications - 3.6L V8 - TdV8/5.0L NA V8 - AJ133/5.0L SC V8 - AJ133»(/land-rover/range-rover/l322-2009-2012/remont/ac-compressor/#climate-control-system-general-information__specifications) .
  13. Disconnect the high and low pressure connections.
  14. See figure NOTE: Some variation in the illustrations may occur, but the essential information is always correct. Install and firmly tighten the caps that cover the high and low pressure connections.
