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 opened refrigerant line and evaporator tube fittings and all the expansion valve ports.
2. Lubricate new rubber O-ring seals with clean refrigerant oil and install them onto the refrigerant line and 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. Position the A/C expansion valve (3) onto the evaporator tube tapping plate (3) and install the two retaining bolts (1). Tighten the bolts to 11 Nm (97 in. lbs.).




4. Connect the A/C liquid line (2) and A/C suction line (3) to the A/C expansion valve (4) and install the retaining nut (1). Tighten the nut to 23 Nm (17 ft. lbs.).
5. Install the nut that secures the A/C liquid line to the right front strut tower A/C Line - Installation. Tighten the nut securely.
6. Install the air cleaner housing and air inlet tube Air Cleaner Housing - Installation.
7. Reconnect the negative battery cable.
8. Evacuate the refrigerant system Refrigerant System Evacuate.
9. Adjust the refrigerant oil level Refrigerant Oil Level.
10. Charge the refrigerant system Refrigerant System Charge.
