Refrigerant Oil Adding
REFRIGERANT OIL ADDING
CAUTION:Electric A/C Compressor Oil only must be used as a refrigerant system lubricant for hybrid vehicles. Addition of any oil other than Electric A/C Compressor Oil to the hybrid vehicle refrigerant system will damage the electric Air Conditioning (A/C) compressor and contaminate the refrigerant system.
CAUTION:Do not use the R-134a Refrigerant Management Machine built-in oil injection system to inject Electric A/C Compressor Oil to the refrigerant system on hybrid vehicles equipped with an electric Air Conditioning (A/C) compressor if it has been previously used to inject PAG oil. For hybrid vehicles, use only clean manual injection tools. Injection of Electric A/C Compressor Oil into a hybrid vehicle with equipment previously used with PAG oil will contaminate and damage the hybrid A/C system.
CAUTION:During normal Air Conditioning (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.
1 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.
2 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.
Adding Refrigerant Oil After A/C Compressor Replacement - Non-Hybrid
NOTE:Service 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 PAG oil in a clean measuring cup.
- Add the same amount plus the amount collected during refrigerant recovery.
Adding Refrigerant Oil After Electric A/C Compressor Replacement - Hybrid
CAUTION:Electric A/C Compressor Oil only must be used as a refrigerant system lubricant for hybrid vehicles. Addition of any oil other than Electric A/C Compressor Oil to the hybrid vehicle refrigerant system will damage the electric Air Conditioning (A/C) compressor and contaminate the refrigerant system.
CAUTION:Do not use the R-134a Refrigerant Management Machine built-in oil injection system to inject Electric A/C Compressor Oil to the refrigerant system on hybrid vehicles equipped with an electric Air Conditioning (A/C) compressor if it has been previously used to inject PAG oil. For hybrid vehicles, use only clean manual injection tools. Injection of Electric A/C Compressor Oil into a hybrid vehicle with equipment previously used with PAG oil will contaminate and damage the hybrid A/C system.
NOTE:Service electric A/C compressors are shipped with 60 ml (2 fl oz) of electric A/C compressor oil already installed.
1. Drain the oil from the old electric compressor into a clean measuring cup.
- If the amount of oil drained is less than or equal to 60 ml (2 fl oz), add the amount of oil collected by the R-134a Refrigerant Management Machine during refrigerant recovery to the low-side service port after the new electric A/C compressor is installed and the system has been evacuated.
- If the amount of oil drained is greater than 60 ml (2 fl oz), add the difference between the amount collected and 60 ml (2 fl oz), plus the amount collected by the R-134a Refrigerant Management Machine during refrigerant recovery, to the low-side service port after the new electric A/C compressor is installed and the system has been evacuated.
Oil Injection Using a Dye/Lubricant Injector
CAUTION:Electric A/C Compressor Oil only must be used as a refrigerant system lubricant for hybrid vehicles. Addition of any oil other than Electric A/C Compressor Oil to the hybrid vehicle refrigerant system will damage the electric Air Conditioning (A/C) compressor and contaminate the refrigerant system.
CAUTION:Do not add liquid based R-134a Leak Detection Dye to the refrigerant system on hybrid vehicles equipped with an electric A/C compressor. Liquid based dyes are mixed with PAG oil, and will contaminate and damage the hybrid refrigerant system. Dye can only be added to hybrid vehicles by installing a new receiver/drier which includes a fluorescent dye "wafer" which will dissolve after approximately 30 minutes of continued A/C operation.
NOTE:The dye/lubricant injector is included as part of the 219-00069 R-134a Loop/Add On Injector Kit-Set.
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. See Air Conditioning (A/C) System Evacuation And Charging.
2. Assemble the dye/lubricant injector using the correct adapters 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 new refrigerant compressor oil.
5. Install the dye/lubricant injector between the low-side service gauge port valve and the refrigerant service station or manifold gauge set.
6. Open all valves and charge the refrigerant system. See Air Conditioning (A/C) System Evacuation And Charging.
