INSTALLATION
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system. 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.
NOTE: Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is opened. Failure to replace the rubber O-ring
seals and metal gaskets could result in a refrigerant system leak.
1. Position the A/C liquid line (1) into the engine compartment.
2. Remove the tape or plugs from the opened liquid and suction line fittings and the receiver/drier and expansion valve ports.

of a special material for the R-134a system. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
4. Connect the A/C liquid line to the A/C expansion valve (2) and engage the two liquid line retainer clips (4) to the frame rail (3).
