Repair Procedures

Removal

1. If the compressor is marginally operable, run the engine, and let the air conditioning work for a few minutes, then shut the engine off.
2. Do not use the same A/C recovery / charging station as conventional belt-driven compressors.
3. Since the electric compressor uses high-voltage, you should use PVE oil which have high Volumetric Resistivity.
4. If the PVE oil of the system gets mixed PAG oil, then dielectric breakdown due to decreased volumetric Resistivity can occur and inoperative A/C compressor may result, A/C compressor may not work.
5. Shut off the high voltage circuit.
6. Recover the refrigerant with a recovery/charging station.
7. Loosen the mounting bolts and then remove the under cover(A).




8. Loosen the mounting bolts and clip then remove the wheel house(A).




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




10. Disconnect the compressor low voltage connector and then remove 6 mounting bolts and the compressor(A).






Installation

1. Make sure of the length of compressor mounting bolts, and then tighten it A->B->C->D->E->F order.

Tightening torque :
10 - 15 N.m (2.04 - 3.36 kgf.m, 7.37 - 11 lb-ft)




2. Install in the reverse order of removal, and note these items.
A. 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 105 - 125cc(3.7 - 4.4 oz.) the result is the amount of oil you should drain from the new compressor (through the suction fitting).
B. 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.
C. To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other refrigerant oils.
D. Immediately after using the oil, replace the cap on the container and seal it to avoid moisture absorption.
