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 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 .
10. Adjust the refrigerant oil level .
11. Charge the refrigerant system .
12. Install the air cleaner housing Air Cleaner Body - Installation.
