Removal & Installation
Only a MVAC-trained, EPA-certified, automotive technician should service the A/C system or its components. When servicing the A/C system, please note the precautions at the beginning of this section.
- Loosen the tension pulley, then remove the drive belt.
- Discharge the A/C refrigerant, as outlined in this section.
- Disconnect the discharge and suction hoses.
- Unfasten the retaining bolts, then remove the compressor.
Installation is the reverse of the removal procedure. Tighten the compressor mounting bolts to 14-21 ft. lbs. (20-30 Nm).
- If the compressor is operable at all, run the engine at idle and let the A/C run for a few minutes, then shut the engine off.
- Disconnect the negative battery cable.
- Recover the refrigerant with a recovery/charging station, as outlined earlier in this section.
- Loosen the drive belt.
Remove the bolts, then disconnect the suction line (A) and discharge line (B) from the compressor. Plug or cap the lines immediately to prevent moisture and debris from entering the system.
Disconnect the compressor clutch connector (A), and then remove 4 mounting bolts and the compressor. Note the different lengths of the compressor mounting bolts when removing them.
Installation is the reverse of the removal procedure, noting the following:
- 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 210cc(7.1 fl.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. 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 A/C system.
