Compressor Replacement
CompressorCompressor:
1. If the compressor is marginally operable, run the engine at idle speed, and let the air conditioner work a few minutes. Then shut the engine OFF.
2. Recover the refrigerant with a Recovery/Recycling/Charging System Refrigerant Recovery.
3. Remove the power steering pump.
NOTE: Do not disconnect the hoses from the power steering pump.
4. Disconnect the condenser fan connector. Disconnect the compressor clutch connector, then remove the compressor clutch connector and the clips from the condenser fan shroud. Remove the two mounting bolts and the condenser fan shroud.
NOTE: Be careful not to damage the radiator fins when removing the condenser fan shroud.
5. Remove the bolts, then disconnect the suction line and the discharge line from the compressor.
NOTE: Plug or cap the lines immediately after disconnecting to avoid moisture and dust contamination.
6. Loosen the adjust pulley bracket pivot bolt and the adjusting bolt, then remove the A/C compressor belt from the pulley as shown.
7. Remove the four mounting bolts and the compressor.
NOTE: Be careful not to damage the radiator fins when removing the compressor.
8. Remove the four bolts and the suction service valve from the compressor.
9. If necessary, remove the compressor bracket as follows.
- Remove the engine mount nut and the washer.
NOTE: When tightening the engine mount nut, make sure the washer is set properly on the left front engine mount as shown.
- Remove the four mounting bolts and the compressor bracket.
10. Install in the reverse order of removal, and:
- 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 140 ml (4 2/3 fl.oz, 4.93 imp.oz); 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.
NOTE: Be sure to use the right O-rings for HFC-134a (R-134a) to avoid leakage.
- use refrigerant oil (ND-OIL 8: P/N 38899 - PR7 - A01) for R-134a Nippondenso piston type 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, replace the cap on the container, and seal it to avoid moisture absorption.
- do not spill the refrigerant oil on the car; it may damage the paint; if the refrigerant oil contacts the paint, wash it off immediately.
- do not damage the radiator fins when installing the condenser fan shroud and the compressor.
- adjust the A/C compressor belt.
- adjust the power steering pump belt.
- charge the system Charging the System and test its performance Performance Test.
