Lubricant Adjustment Procedure for Compressor Replacement
WARNING: This page is about a different car, the 2005 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.
- Before connecting recovery/recycling equipment to vehicle, check recovery/recycling equipment gauges. No refrigerant pressure should be displayed. If NG, recover refrigerant from equipment lines.
- Connect recovery/recycling equipment to vehicle. Confirm refrigerant purity in supply tank using recovery/recycling equipment and refrigerant identifier. If NG, refer to "CONTAMINATED REFRIGERANT ".
- Confirm refrigerant purity in vehicle A/C system using recovery/recycling equipment and refrigerant identifier. If NG, refer to "CONTAMINATED REFRIGERANT ".
- Discharge refrigerant into the refrigerant recovery/recycling equipment. Measure lubricant discharged into the recovery/recycling equipment.
- Drain the lubricant from the "old" (removed) compressor into a graduated container and recover the amount of lubricant drained.
- Drain the lubricant from the "new" compressor into a separate, clean container.
- Measure an amount of new lubricant installed equal to amount drained from "old" compressor. Add this lubricant to "new" compressor through the suction port opening.
- Measure an amount of new lubricant equal to the amount recovered during discharging. Add this lubricant to "new" compressor through the suction port opening.
- If the liquid tank also needs to be replaced, add an additional 5 m l (0.2 US FL oz., 0.2 Imp fl. oz.) of lubricant at this time.CAUTION: Do not add this 5 m l (0.2 US fl. oz., 0.2 Imp fl. oz.) of lubricant if only replacing the compressor.
