CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system See: Service and
Repair/Procedures/Refrigerant Oil Level. Failure to properly adjust the refrigerant oil level will prevent the A/C system from operating as
designed and can cause serious A/C compressor damage.
NOTE: When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be
added to the refrigerant system See: Service and Repair/Procedures/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 may result in a refrigerant system leak.
