OILMaintenance of Oil Quantity in Compressor
The oil in the compressor circulates through the system with the refrigerant. Add oil to compressor when replacing any component or after a large refrigerant leakage occurred. It is important to maintain the specified amount.
If oil quantity is not maintained properly, the following malfunctions may result:
- Lack of oil: May lead to a seized compressor.
- Excessive oil: Inadequate cooling (thermal exchange interference)

OIL ADJUSTING PROCEDURE FOR COMPONENTS REPLACEMENT EXCEPT COMPRESSOR
OIL ADJUSTING PROCEDURE FOR COMPRESSOR REPLACEMENT
1. 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.
2. Discharge refrigerant into the refrigerant recovery/recycling equipment. Measure oil discharged into the recovery/recycling equipment.
3. Drain the oil from the old (removed) compressor into a graduated container and recover the amount of oil drained.
4. Drain the oil from the new compressor into a separate, clean container.
5. Measure an amount of new oil installed equal to amount drained from old compressor. Add this oil to new compressor through the suction port opening.
6. Measure an amount of new oil equal to the amount recovered during discharging. Add this oil to new compressor through the suction port opening.
7. If the liquid tank also needs to be replaced, add another 5 ml (0.2 US fl oz, 0.2 Imp fl oz.) of oil at this time.
Add this 5 ml (0.2 US fl oz, 0.2 Imp fl oz.) of oil only when replacing the compressor.
