Removal and Replacement

COMPRESSOR

REPLACEMENT
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. Disconnect the negative cable from the battery.
3. Recover the refrigerant with a recovery/charging station.
4. Loosen the drive belt.




5. Remove the nuts, then disconnect the suction line (A) and discharge (B) line from the compressor. Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.




6. Disconnect the compressor clutch connector (A), then remove the mounting bolts and the compressor (B).




7. Using a hexagon wrench (6mm) remove the bolts, the manifold assembly (A) and the gasket (B) from the compressor.
8. Install in the reverse order of removal, and note these items.
- 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 150 ml 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 R-134a to avoid leakage.
- 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, 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 drive belt.
- Charge the system, and test its performance.
