A/C compressor damage.
NOTE: When replacing multiple A/C system components, see the Refrigerant Oil Capacities chart to determine how much oil should be added
to the refrigerant systemSee: Service and Repair/Refrigerant Oil Level .
NOTE: Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is disconnected. Failure to replace
the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.
