Removal & Installation



2001 Models

WARNING
Refer to the precautions at the beginning of this section. Only a MVAC-trained, EPA-certified, automotive technician should service the A/C system or its components.

  1. If the A/C compressor is somewhat operable, run the engine at idle speed, and let the air conditioning work for a few minutes, then shut the engine off.
  2.  
  3. Disconnect the negative cable from the battery.
  4.  
  5. Recover the refrigerant with a recovery/recycling/charging station, as outlined earlier in this section.
  6.  
  7. Disconnect the condenser fan connector. Remove the compressor clutch connector and the wire harness clip from the condenser fan shroud, then disconnect the compressor clutch connector. Remove the mounting bolts and the condenser fan shroud.
  8.  
  9. Remove each bolt, then disconnect the suction and discharge lines from the compressor. Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.
  10.  
  11. Remove the power steering pump belt, as outlined in the Engine Mechanical Section.
  12.  
  13. Loosen the pivot bolt of the idler pulley bracket and the adjusting bolt, then remove the A/C compressor belt from the pulleys. If necessary, remove the mounting bolts from the left front mount, then remove the A/C compressor belt through the gap between the body and the left front mount.
  14.  
  15. Remove the mounting bolts and the compressor.
  16.  
  17. If necessary, remove the compressor bracket as follows.
    1. Remove the nut and the washer from the left front mount. When tightening the nut to the left front mount, make sure the washer is set properly on the left front mount as shown.
    2.  
    3. Remove the mounting bolts and the compressor bracket.
    4.  

  18.  
  19. Check the idler pulley bearing for play and drag, and replace it with a new one if it's noisy or has excessive play or drag.
  20.  

To install:

  1. Installation is the reverse of the removal procedure, noting the following:

    If you're installing a new compressor, drain all the refrigerant oil from the removed compressor, and measure its volume. Subtract the volume of drained oil from 130 (4 1/3 fl-oz, 4.6 Imp-oz); the result is the amount of oil you should drain from the new compressor (through the suction fitting).
     
    Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them. Be sure to use the right O-rings for HFC-134a (R-134a) to avoid leakage.
     
    Use refrigerant oil (SP-10) for R-134a KEIHIN spiral type compressors only.
     
    To avoid contamination, never return the oil to the container once dispensed, and never mix it with other refrigerant oils.
     
    Immediately after using the oil, replace the cap on the container, and seal it to avoid moisture absorption.
     
    Do not spill the refrigerant oil on the vehicle; it may damage the paint; if the refrigerant oil contacts the paint, wash it off immediately.
     
    Adjust the A/C compressor belt and the power steering pump belt, as outlined in the Engine Mechanical Section.
     

  2.  
  3. Charge the A/C system, as outlined in this section.

WARNING
Refer to the precautions at the beginning of this section. Only a MVAC-trained, EPA-certified, automotive technician should service the A/C system or its components.

  1. If the A/C compressor is somewhat operable, run the engine at idle speed, and let the air conditioning work for a few minutes, then shut the engine off.
  2.  
  3. Make sure you have the anti-theft code for the radio, then write down the frequencies for the radio's preset buttons.
  4.  
  5. Disconnect the negative battery cable.
  6.  
  7. Recover the refrigerant with a recovery/recycling/charging station, as outlined earlier in this section.
  8.  
  9. Remove the radiator reservoir tank.
  10.  
  11. Remove the alternator, as outlined in the Engine Electrical Section.
  12.  
  13. Disconnect the A/C compressor clutch connector (A), remove the bolt and nut, then disconnect the suction line (B) and the discharge line (C) from the A/C compressor. Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.

  15. Remove the mounting bolts and the A/C compressor.
  16.  

To install:

  1. Install the A/C compressor in the reverse order of removal, and note these items:

    If you're A/C installing a new A/C compressor, you must calculate the amount of refrigerant oil to be removed from it.
     
    Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them. Be sure to use the correct O-rings for HFC-134a (R-134a) to avoid leakage.
     
    Use refrigerant oil (KEIHIN SP-10) for HFC-134a KEIHIN spiral type A/C compressor only.
     
    To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other refrigerant oils.
     
    Immediately after using the oil, reinstall the cap on the container, and seal it to avoid moisture absorption.
     
    Do not spill the refrigerant oil on the vehicle; it may damage the paint. If the refrigerant oil contacts the paint, wash it off immediately.
     

  2.  
  3. Charge the system, as outlined earlier in this section.
  4.  
  5. Perform the ECM/PCM idle learn procedure, as follows:
    1. Make sure all electrical items (A/C, audio, rear window defogger, lights, etc.) are off.
    2.  
    3. Reset the ECM/PCM with the HDS, or equivalent OBD-II compliant scan tool.
    4.  
    5. Turn the ignition switch ON (II), and wait 2 seconds.
    6.  
    7. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator fan comes on, or until the engine coolant temperature reaches 194 °F (90 °C).
    8.  
    9. Let the engine idle about 5 minutes with the throttle fully closed.
      NOTE
      If the radiator fan comes on, do not include its running time in the 5 minutes.


      NOTE
      Resetting the power window control unit is required after performing the following procedures: Disconnecting the battery, Removing the No. 6 (7.5 A) and/or the No. 23 (20 A) fuses from the under-dash fuse/relay box or disconnecting the driver's door wire harness.
