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 is required anytime the A/C expansion valve is removed. Failure to replace the rubber O-ring seals may result in a refrigerant system leak.





1. Remove the tape or plugs from the 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 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 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 6 Nm (53 in. lbs.).




5. Lubricate new rubber O-ring seals with clean refrigerant oil and install them on the refrigerant line 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.

CAUTION: Use care when installing the A/C lines to the A/C expansion valve. Carefully align the tube ends with the valve prior to tightening the A/C line retaining nut or damage to the sealing rings and tube ends may occur.

6. Install the A/C liquid line (1) and the A/C suction line (2) onto the A/C expansion valve (3).
7. Install the nut (4) that secures the A/C liquid line and the A/C suction line to the A/C expansion valve. Tighten the nut to 6 Nm (53 in. lbs.).
8. Reconnect the negative battery cable.
9. Evacuate the refrigerant system Refrigerant System Evacuate.
10. Adjust the refrigerant oil level Refrigerant Oil Level.
11. Charge the refrigerant system Refrigerant System Charge.
12. Install the air cleaner housing Service and Repair.
