Refrigerant Oil Adding: Filling
NOTE:
Motorcraft® Electric A/C
Compressor POE YN-32 oil only must be used as a refrigerant system lubricant for HEV
(Hybrid Electric Vehicles). Addition of any oil other than Motorcraft® Electric A/C
Compressor POE YN-32 oil to the High Voltage Battery Electric vehicle refrigerant system will damage the electric A/C
compressor and contaminate the refrigerant system.
NOTE:
Do not use the R-134a Refrigerant Management Machine built-in oil injection system to inject Motorcraft Electric A/C
Compressor POE YN-32 oil to the refrigerant system on HEV
(Hybrid Electric Vehicles) equipped with an electric A/C
) compressor if it has been previously used to inject PAG oil. For HEV
(Hybrid Electric Vehicles), use only clean manual injection tools. Injection of Motorcraft Electric A/C
Compressor POE YN-32 oil into a HEV
(Hybrid Electric Vehicles) with equipment previously used with PAG oil will contaminate and damage the High Voltage Battery Electric A/C
system.
NOTE:
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.
