Compressor HVAC: Service and Repair

A/C COMPRESSOR REMOVAL/INSTALLATION [L3, AJ]

1. Disconnect the negative battery cable.
2. Discharge the refrigerant from the system. (See REFRIGERANT CHARGING [L3, AJ].)
3. Remove the right side splash shield and mudguard.
4. Remove the WU-TWC. (AJ only)
5. Loosen the drive belt and remove it.

CAUTION
- If moisture or foreign material enters the refrigeration cycle, cooling ability will be lowered and abnormal noise will occur. Always immediately plug open fittings after removing any refrigeration cycle parts to keep moisture or foreign material out of the cycle.
6. Remove in the order indicated in the table. Do not allow compressor oil to spill.






7. Install in the reverse order of removal.
8. Adjust the drive belt.
9. Perform the refrigerant system performance.(See REFRIGERANT SYSTEM PERFORMANCE TEST [L3, AJ].) Refrigerant System Performance Test

A/C Compressor Installation Note

CAUTION Due to the high moisture-absorption characteristics of the compressor oil, it may absorb moisture if left over a long period of time thereby negatively affecting A/C operation. Drain the compressor oil and refill within 10 mm. of each other.

1. Rotate new A/C compressor shaft six to eight revolutions while collecting refrigerant oil in a clean measuring device. Use this refrigerant oil to refill new compressor. Do not allow refrigerant oil to become contaminated.
2. Rotate old A/C compressor shaft six to eight revolutions while collecting refrigerant oil in a separate, clean measuring device.
3. Compare those oil amounts. The amount of the oil drained from the new A/C compressor should be greater than the old one.




4. Pour the same amount oil of drained from the A/C compressor back into the new A/C compressor.

A/C compressor oil type
- ZXL 1OOPG

A/C compressor oil sealed volume (approx. quantity)
- 150 m1{l50 cc, 5.07 fl oz}
