-
If the amount of oil that was removed from the old A/C compressor is greater than 142 ml (5 oz), pour the same amount drained of clean PAG
Refrigerant Compressor Oil (R-134a Systems) or equivalent into the new A/C compressor.
-
If the amount of oil that was removed from the old A/C compressor is less than 85 ml (3 oz), pour 85 ml (3 oz) of clean A/C Refrigerant
Compressor Oil (R-134a Systems) or equivalent into the new A/C compressor.

2. Rotate the old A/C compressor shaft 6 to 8 revolutions while collecting oil in a clean measuring device.
-
If the amount of oil drained from the old A/C compressor is less than 89 ml (3 oz), remove 118 ml (4 oz) from the new A/C compressor.
-
If the amount of oil drained from the old A/C compressor is 89 ml (3 oz), remove 89 ml (3 oz) from the new A/C compressor.
-
If the amount of oil drained from the old A/C compressor is 118 ml (4 oz), remove 59 ml (2 oz) from the new A/C compressor.
-
If the amount of oil drained from the old A/C compressor is 148 ml (5 oz), remove 29 ml (1 oz) from the new A/C compressor.
-
If the amount of oil drained from the old A/C compressor is greater than 148 ml (5 oz), remove 0 ml (0 oz) from the new A/C compressor.
Adding Refrigerant Oil After New Suction Accumulator or Receiver/Drier Replacement
NOTE: This refrigerant oil adding method is to be used when a new suction accumulator or receiver drier only has been installed. If a new A/C
compressor and evaporator core orifice or TXV have also been installed due to system contamination, refer to the appropriate heading.
1. Drill one 12.7 mm (1/2 in) hole in the old suction accumulator or receiver/drier cylinder and drain the oil into a clean measuring cup.
2. Add the same quantity of new PAG oil, plus the amount collected during refrigerant recovery and 60 ml (2 fl oz).
Adding Refrigerant Oil After Multiple Component Replacement After A/C System Contamination
NOTE: This refrigerant oil adding method is to be used when a new A/C compressor, suction accumulator or receiver drier and evaporator core orifice
or TXV have been installed due to system contamination and the A/C system has been flushed.
NOTE: Service A/C compressors are shipped without refrigerant oil.
1. Add 60 ml (2 fl oz) directly to the new A/C compressor suction port.
2. Inject the total vehicle PAG oil capacity minus 60 ml (2 fl oz) to the low-side service port during system charging. For the total PAG oil capacity
specification, refer to the Specifications table.
Oil Injection Using a Dye/Lubricant Injector
NOTE: If fluorescent leak detection dye is also to be added during A/C charging, the dye may be added to the dye/lubricant injector, from the R-134a
Loop/Add On Injector Kit-Set, along with the PAG oil.
1. Evacuate the refrigerant system. For additional information, refer to Air Conditioning (A/C) System Recovery, Evacuation and Charging See:
Heating and Air Conditioning/Service and Repair/Air Conditioning (A/C) System Recovery, Evacuation and Charging.
2. Assemble the dye/lubricant injector and the correct adapters from the R-134a Loop/Add On Injector Kit-Set to match the amount of refrigerant
compressor oil to be injected.
3. Verify that all the valves on the dye/lubricant injector are closed.
4. Fill the dye/lubricant injector with the correct amount of clean, new PAG oil.
