Compressor HVAC: Service and Repair
A/C Compressor ReplacementNOTE: Since the oil separator is equipped inside the A/C compressor for this vehicle, oil drainage is unnecessary at the time of A/C compressor replacement.
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. Make sure you have the anti-theft code for the audio system, then write down the audio presets.
3. Disconnect the negative cable from the battery.
4. Recover the refrigerant with a recovery/recycling/charging station.
5. Remove the splash shield.
6. Remove the drive belt.
7. Remove the bolts, then disconnect the suction line (A) and the discharge line (B) from the A/C compressor, and remove the O-rings (C). Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.
8. Remove the mounting bolts and the A/C compressor.
9. Install the A/C compressor in the reverse order of removal, and note these items:
- 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 HFC-134a spiral 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.
- Enter the anti-theft code for the audio system, then enter the audio presets.
