Level. Failure to properly adjust the refrigerant oil level will prevent the A/C system from operating as designed and can cause serious A/C
compressor damage.
NOTE: When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be
added to the refrigerant system See: Service and Repair/Refrigerant Oil Level.
NOTE: If only the A/C evaporator is being replaced, add 60 milliliters (2 fluid ounces) of refrigerant oil to the refrigerant system. Use only
refrigerant oil of the type recommended for the A/C compressor in the vehicle.
