Lubricant Adjusting Procedure For Compressor Replacement
WARNING: This page is about a different car, the 2003 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.
- Before connecting ACR4 to vehicle, check ACR4 gauges. No refrigerant pressure should be displayed. If NG, recover refrigerant from equipment lines.
- Connect ACR4 to vehicle. Confirm refrigerant purity in supply tank using ACR4 and refrigerant identifier. If NG, refer to CONTAMINATED REFRIGERANT .
- Confirm refrigerant purity in vehicle A/C system using ACR4 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 ml (0.2 US fl oz., 0.2 Imp fl oz.) of lubricant at this time.
Do not add this 5 ml (0.2 US fl oz., 0.2 Imp fl oz.) of lubricant if only replacing the compressor.
