Lubricant Adjusting Procedure for Compressor Replacement
WARNING: This page is about a different car, the 2003 Infiniti I35. 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.
- Remove the drain plug of the "old" (removed) compressor. Drain the lubricant into a graduated container and record the amount of drained lubricant.
- Remove the drain plug and 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.
- Torque the drain plug.
- 18 - 19 N.m (1.8 - 1.9 kg-m, 13 - 14 ft-lb)
- If the liquid tank also needs to be replaced, add an additional 5 ml (0.2 US fl oz, 0.2 lmp fl oz) of lubricant at this time. Do not add this 5 ml (0.2 US fl oz, 0.2 lmp fl oz) of lubricant if only replacing the compressor.
