Refrigerant Oil: Service and Repair
REFRIGERANT OIL ADDING
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.
Refrigerant Oil Adding for New A/C Compressor Installation
NOTE:This PAG oil adding method is to be used when a new A/C compressor only has been installed. If a new suction accumulator or receiver drier
and evaporator core orifice or Thermostatic Expansion Valve (TXV) have also been installed due to system contamination, refer to the appropriate
heading.
NOTE:Service A/C compressors are shipped without refrigerant oil.
1. Rotate the old A/C compressor shaft 8 to 10 full rotations clockwise to discharge the PAG oil through the A/C compressor discharge port, while
collecting the PAG oil in a clean measuring cup.
-
Add the same amount of new PAG oil plus the amount collected during refrigerant recovery plus 30 ml (1 fl oz).
Refrigerant Oil Adding for New Suction Accumulator or Receiver/Drier Installation
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 oz).
Refrigerant Oil Adding for Multiple Component Installation 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.
