INSTALLATION

CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system 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 Refrigerant Oil Level.

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. Remove the tape or plugs from the opened evaporator tube and extension tube fittings and all rear expansion valve ports.
2. Lubricate new rubber O-ring seals with clean refrigerant oil and install them on the evaporator tube and extension tube fittings. Use only the specified O-rings as they are made 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.
3. Install the rear A/C expansion valve (4) between the rear A/C evaporator tubes (2) and the rear extension tube tapping block (5).
4. Install the two bolts (3) that secure the rear A/C expansion valve between the rear A/C evaporator tubes and the rear extension tube tapping block. Tighten the bolts to 11 Nm (97 in. lbs.).
5. Install a new insulator (1) around the rear A/C evaporator tubes.
6. Install the right rear quarter panel trim Quarter Trim Panel - Installation.
7. Evacuate the refrigerant system Refrigerant System Evacuate.
8. Adjust the refrigerant oil level Refrigerant Oil Level.
9. Charge the refrigerant system Refrigerant System Charge.
