INSTALLATION
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system See: Specifications/Capacity
Specifications/Refrigerant Oil Capacity . 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: Specifications/Capacity Specifications/Refrigerant Oil Capacity .
NOTE: Replacement of the refrigerant line O-ring seals is required anytime a refrigerant line or expansion valve is disconnected. Failure to
replace the rubber O-ring seals could result in a refrigerant system leak.
1. Remove the tape or plugs from the rear evaporator tube and extension line fittings and all rear expansion valve ports.
2. Lubricate new rubber O-ring seals with clean refrigerant oil and install them onto rear evaporator tube and extension line fittings. Use only the
specified O-rings as they are made of a special material for the R-134a refrigerant system. Use only refrigerant oil of the type recommended for the
A/C compressor in the vehicle.
