2002 Honda Civic SiSECTION Compressor Replacement
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Honda Odyssey, 2003 Honda Odyssey, 2002 Honda Odyssey, 2001 Honda Odyssey, and 2000 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
  1. If the compressor is marginally operable run the engine at idle speed, and let the air conditioning work for a few minutes, then shut the engine off.
  2. Make sure you have the anti-theft code for the radio and the navigation system, then write down the frequencies for the radio's preset buttons.
  3. Disconnect the negative cable from the battery.
  4. Recover the refrigerant with a recovery/recycling/charging station (see Refrigerant Recovery  ).
  5. Remove the alternator (see REPLACEMENT ).
  6. Remove the splash shield (see step 28 on ENGINE ).
  7. Remove the bolt and the nuts, then disconnect the suction line (A) and discharge line (B) from the compressor. Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.

  10. Install the compressor in the reverse order of removal and note these items:
    • If you're installing a new compressor, you must calculate the amount of refrigerant oil to be removed from it (see A/C Service Tips and Precautions  ).
    • 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 (DENSO ND-OIL 8) for HFC-134a DENSO piston type 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.
    • Charge the system (see System Charging  ).
    • Do the PCM idle learn procedure (see PCM IDLE LEARN PROCEDURE ).
    • Do the power window control unit resetting procedure (see RESETTING THE POWER WINDOW CONTROL UNIT '03-04 ).
    • Enter the anti-theft code for the radio and the navigation system, then enter the customer's radio station presets.
