Compressor Oil Level Check, Inches [2]
Compressor Clutch Air Gap, Inches 0.020 - 0.035

[1] Use a polyalkalene glycol PAG lubricant part No. 82300102, or equivalent,w/R-134a systems.

[2] Compressor oil level need only be checked when there is evidence of oil loss from the system as in the case of a broken line, leaking fitting or component, defective compressor seal or collision damage to system. A wet, shiny surface around a leak point is evidence of oil loss. These compressors must be removed from vehicle and drained to check the oil level, proceed as follows:
1. Discharge system as outlined in "A/C System Testing," and repair leak as necessary.
2. Disconnect suction and discharge lines from compressor, then remove compressor and clutch assembly from vehicle.
3. Invert compressor and drain oil through suction and discharge ports.
4. Determine the correct amount of oil to add to compressor by subtracting the amount of oil remaining in other components.
5. Add oil to compressor through suction port.
6. Reinstall compressor using new gaskets on refrigerant line fittings, then evacuate and recharge system.
