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 is required anytime a refrigerant line is disconnected. Failure to replace the rubber O-ring seals may result in a refrigerant system leak.





1. Remove the tape or plugs from the opened refrigerant lines and evaporator tube fittings and all of the expansion valve ports.
2. Lubricate new rubber O-ring seals with clean refrigerant oil and install them on the rear evaporator 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 (2) onto the rear A/C evaporator.
4. Install the two bolts (1) that secure the rear A/C expansion valve to the rear A/C evaporator. Tighten the bolts to 6 Nm (53 in. lbs.). Make sure to reposition the insulation back around the expansion valve.
5. Connect the rear refrigerant lines to the rear A/C expansion valve .
6. Install the rear roof ducts .
7. Reconnect the negative battery cable.
8. Evacuate the rear refrigerant system .
9. Adjust the refrigerant oil level .
10. Charge the rear refrigerant system .
