Refrigerant Oil





COMPRESSOR OIL CAPACITIES






CAUTION: Be certain to adjust the refrigerant system oil level when replacing an A/C compressor. The refrigerant oil in this A/C compressor can only be drained using the procedure described below. Failure to properly drain the refrigerant oil from the A/C compressor can prevent the A/C system from operating as designed and cause serious compressor damage.

NOTE: When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be removed from the new A/C compressor (example: new compressor and receiver/drier requires 80 ml. (2.7 oz.) of oil to be added to the system. 100 ml. (3.4 oz.) of oil is in new compressor. 100 ml. (3.4 oz.) minus 80 ml. (2.7 oz.) equals 20 ml. (0.7 oz.) oil to be drained from new compressor).

This A/C compressor is filled with 100 milliliters (3.4 oz.) from the factory. When only the A/C compressor is being replaced, 50 milliliters (1.7 oz.) of refrigerant oil must first be drained from the new compressor prior to installation. Use the following procedure to drain and measure refrigerant oil from the A/C compressor.
