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 systemRefrigerant 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 evaporator tube fittings and all of the expansion valve ports.
2. Lubricate new O-ring seals with clean refrigerant oil and install them onto the evaporator tube fittings. Use only the specified seals 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 A/C expansion valve (2) onto the evaporator tube tapping block (3).
4. Install the two bolts (1) that secure the A/C expansion valve to the evaporator tube tapping block. Tighten the bolts to 11 Nm (97 in. lbs.).





5. Remove the tape or plugs from the A/C suction line (2) and the A/C liquid line (3).
6. Lubricate new O-ring seals with clean refrigerant oil and install them onto the A/C suction and liquid lines. Use only the specified seas 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.
7. Connect the A/C suction and liquid lines to the A/C expansion valve (4).
8. Install the nut (1) that secures the A/C suction and liquid lines to the A/C expansion valve. Tighten the nut to 20 Nm (15 ft. lbs.).
9. On gasoline engine equipped models, install the air intake tube and the resonator Air Cleaner Body - Installation.
10. Reconnect the negative battery cable.
11. Evacuate the refrigerant system Refrigerant System Evacuate.
12. Adjust the refrigerant oil level Refrigerant Oil Level.
13. Recharge the refrigerant system Refrigerant System Charge.
