Refrigerant Oil Adding

CAUTION:
CAUTION:During normal A/C operation, oil is circulated through the system with the refrigerant, and a small amount is retained in each component. If certain components of the system are removed, some of the refrigerant oil will go with the component. To maintain the original total oil charge, it is necessary to compensate for the oil lost by adding oil to the system with the new part.
  1. Refer to the chart below for refrigerant oil adding amounts and methods of installation.
    Component PAG Oil Amount Method of Adding
    A/C compressor Varies Add directly to A/C compressor before installation
    Suction accumulator or receiver/drier Varies Add directly to the suction accumulator inlet port or inject to the low-side port during system charging
    Evaporator core 89 ml (3 ounces) added to the amount collected during refrigerant recovery Add directly to the evaporator core inlet tube or inject to the low-side port during system charging
    Condenser core 60 ml (2 ounces) added to the amount collected during refrigerant recovery Add directly to the condenser core inlet or inject to the low-side port during system charging
    Evaporator core orifice or thermostatic expansion valve 60 ml (2 ounces) added to the amount collected during refrigerant recovery Inject to the low-side port during system charging
    A/C pressure relief valve 60 ml (2 ounces) added to the amount collected during refrigerant recovery Inject to the low-side port during system charging
    Refrigerant hose/line 60 ml (2 ounces) added to the amount collected during refrigerant recovery

    a

    		 Inject to the low-side port during system charging
    O-ring leak repair 60 ml (2 ounces) added to the amount collected during refrigerant recovery

    b

    		 Inject to the low-side port during system charging
    Port leak repair 60 ml (2 ounces) added to the amount collected during refrigerant recovery Inject to the low-side port during system charging

    a If an excessive amount of refrigerant oil is lost due to a hose rupture/separation or other damage, the total system refrigerant oil capacity must be added.

    b The amount specified may be used for one or multiple O-ring leak repairs. Do not multiply the refrigerant oil amount by the number of O-ring leaks being repaired.

Refrigerant Oil Adding for New A/C Compressor Installation

NOTE:
NOTE:A/C compressors are shipped without refrigerant oil.
  1. Rotate the old A/C compressor shaft 8 to 10 full rotations clockwise while collecting the refrigerant oil in a clean measuring cup.
    • If the amount of oil drained from the old A/C compressor is between 85-142 ml (3-5 ounces), add the same amount plus the amount collected during refrigerant recovery.
    • If the amount of oil drained from the old A/C compressor is greater than 142 ml (5 ounces), add the same amount plus the amount collected during refrigerant recovery.
    • If the amount of oil drained from the old A/C compressor is less than 85 ml (3 ounces), add 85 ml (3 ounces) plus the amount collected during refrigerant recovery.

Refrigerant Oil Adding for New Suction Accumulator or Receiver/Drier Installation

  1. Drill a half-inch hole in the old suction accumulator or receiver/drier cylinder and drain the oil into a clean measuring cup.
  1. Add the quantity of oil drained, plus the amount collected during refrigerant recovery and 60 ml (2 ounces).

Oil Injection Using a Dye/Lubricant Injector

NOTE:
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 along with the refrigerant oil.
  1. Evacuate the refrigerant system. For additional information, refer to Air Conditioning (A/C) System Recovery, Evacuation and Charging in this section.
  1. Assemble the dye/lubricant injector using the correct adapters to match the amount of PAG oil to be injected.

  1. Verify that all the valves on the dye/lubricant injector are closed.

  1. Fill the dye/lubricant injector with the correct amount of clean PAG oil.
  1. Install the dye/lubricant injector between the low-side gauge port valve and the refrigerant station or manifold gauge set.
  1. Open all the valves and charge the refrigerant system. For additional information, refer to Air Conditioning (A/C) System Recovery, Evacuation and Charging in this section.
