Refrigerant Oil Level Check

1. Discharge refrigerant system using recovery/recycling equipment if charge is present.
2. Disconnect refrigerant lines from A/C compressor. Cap the open lines to prevent moisture from entering system.
3. Remove compressor from vehicle.
4. From suction port on top of compressor, drain lubricant from compressor.
5. Add system capacity minus the capacity of components that have not been replaced. Refer to the Lubricant Capacity Chart. Add lubricant through the suction port on compressor. This is not to exceed 133 ml (4.5 oz.) in total.
6. Install compressor and connect refrigerant lines. Then evacuate and charge refrigerant system.
7. Most recovery/recycling equipment will measure the lubricant being removed. This is the amount of lubricant to be added back to the system. If a new compressor is being installed, drain lubricant from old compressor, measure the amount drained and discard old lubricant. Drain the lubricant from the new compressor into a clean container. Return the amount of lubricant measured from the old compressor, plus the amount reclaimed from the system back into the new compressor.
