A/C Compressor Replacement (Without Climate Control)

A/C Compressor Replacement

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 A/C Refrigerant Recovery.

3. Remove the engine cover Engine Removal, and the drive belt Drive Belt Replacement (J35A6).

4. '07 model: Remove the front splash shield. Remove the clips (A) and bolt from the right front inner fender (B). Then move the inner fender to the rear.






5. '08-10 models: Remove the front splash shield Front Splash Shield Replacement. Remove the clips (A) and screw from the right front inner fender (B). Then move the inner fender to the rear.






6. Disconnect the A/C compressor clutch connector (A). Remove the bolt and the nut, then disconnect the suction line (B) and discharge line (C) from the A/C compressor. Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.






7. Remove the mounting bolts and the A/C compressor.





8. Install the compressor in the reverse order of removal, and note these items:

- Inspect the A/C lines for any signs of contamination.
- If you're installing a new A/C compressor, you must calculate the amount of refrigerant oil to be removed from it A/C Refrigerant Oil Replacement (Without Climate Control). A new A/C compressor comes with a full charge of oil.
- 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.
- Charge the system A/C System Charging.
