A/C Compressor Replacement

WARNING: This page is about a different car, the 2011 Acura TL, 2010 Acura TL, and 2009 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Do not install the A/C compressor into a system unless you are completely sure that the system is free of contamination Installing the A/C compressor into a contaminated system can result in premature A/C compressor failure
  1. If the A/C 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. Recover the refrigerant with a recovery/recycling/charging station (see RECEIVER/DRYER DESICCANT REPLACEMENT )
  3. Remove the drive belt (see DRIVE BELT REPLACEMENT )
  4. Remove the condenser fan shroud (see FAN, FAN MOTOR, AND SHROUD REMOVAL AND INSTALLATION )
  5. Disconnect the A/C compressor clutch connector (A). Remove the bolts and the nut, then disconnect the suction hose (B) and the discharge hose (C) from the A/C compressor. Remove the O-rings (D) Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.

  6. Raise the vehicle on a lift, then remove the front splash shield (see FRONT SPLASH SHIELD REPLACEMENT )
  7. Remove the mounting bolts and the A/C compressor (A) Be careful not to damage the radiator fins when removing the compressor

  8. Install the A/C compressor in the reverse order of removal, and note these items
    • Inspect the A/C lines for any signs of contamination
    • 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 only refrigerant oil (DENSO ND-OIL 8) for HFC-134a DENSO A/C compressors 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
    • Be careful not to damage the radiator fins when installing the compressor and the A/C condenser fan shroud
    • Charge the system (see SYSTEM CHARGING )
