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 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. Tighten the nut securely.

6. Install the air cleaner housing and air inlet tube.

7. Reconnect the negative battery cable.

8. Evacuate the refrigerant system.

9. Adjust the refrigerant oil level.

10. Charge the refrigerant system.
