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 Housing
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.
