Refrigerant Oil Adding: Notes
WARNING: This page is about a different variant/trim than selected.
NOTE:
Motorcraft® PAG Refrigerant Compressor Oil YN-12-D only must be used as a refrigerant system lubricant. Addition of any oil other than Motorcraft® PAG Refrigerant Compressor Oil YN-32 to the refrigerant system will damage the Air Conditioning (A/C) compressor and contaminate the refrigerant system.
NOTE:
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.
