1. Remove the battery cover.
2. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [L8, LF].)
3. Discharge the refrigerant from the system. (See REFRIGERANT CHARGING.)
4. Remove the air cleaner. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L8, LF].)
5. Remove the PCM. (See PCM REMOVAL/INSTALLATION [L8, LF].)
6. Remove the drive belt. (See DRIVE BELT REPLACEMENT [L8, LF].)
7. Do not allow remaining compressor oil in the A/C compressor and pipes to spill, and remove in the order indicated in the table.
8. Install in the reverse order of removal.
9. Perform the refrigerant system performance test. (See REFRIGERANT SYSTEM PERFORMANCE TEST.)
1. Rotate new A/C compressor shaft six to eight revolutions while draining new refrigerant oil in a clean measuring device. Use this refrigerant oil to refill new A/C compressor. Do not allow refrigerant oil to become contaminated.
2. Rotate old A/C compressor shaft six to eight revolutions while draining old 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 old A/C compressor back into the new A/C compressor.
