Removal & Installation

Print

  1. Before servicing the vehicle, refer to the precautions section.
  2.  
  3. Disconnect the negative battery cable.
  4.  
  5. Discharge the refrigerant from the system.
  6.  
  7. Remove the right side splash shield and mudguard.
  8.  
  9. Remove the drive belt.
    NOTE
    Do not allow remaining compressor oil in the A/C compressor and pipes to spill, and remove in the order indicated in the table.


    CAUTION
    If moisture or foreign material enters the refrigeration cycle, cooling ability will be lowered and abnormal noise or other malfunction could occur. Always plug open fittings immediately after removing any refrigeration cycle parts.

  10.  
  11. Disconnect the cooler hose (LO) and cooler hose (HI). Do not allow remaining compressor oil in the refrigerant line to spill.
  12.  
  13. Unplug the compressor connector, unfasten the retainers and remove the compressor.
  14.  

To install:

  1. Installation is the reverse of removal. Refer to the illustration for component location and torque values. Keep in mind the following:
    1. Rotate new A/C compressor shaft six to eight revolutions while draining new refrigerant oil in a clean measuring device. Use this refrigerant oil to refill new compressor. Do not allow refrigerant oil to become contaminated.
    2.  
    3. Rotate old A/C compressor shaft six to eight revolutions while draining old refrigerant oil in a separate, clean measuring device.
    4.  
    5. Compare those oil amounts. The amount of the oil drained from the new A/C compressor should be greater than the old one.
    6.  
    7. Pour the same amount oil of drained from the old A/C compressor back into the new A/C compressor. The compressor oil type should be DH-PR and sealed volume should be 5.07 fl. Oz. (150ml).
