INSTALLATION

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.

NOTE: LHD model shown in illustrations. RHD model similar.





1. Remove the tape or plugs from the opened refrigerant line and 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 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. 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. Connect the A/C suction line (1) and the A/C liquid line (4) to the A/C expansion valve (3).
6. Install the nut (2) that secures the A/C suction and liquid lines to the A/C expansion valve. Tighten the nut to 23 Nm (17 ft. lbs.).
7. Reconnect the negative battery cable.
8. Evacuate the refrigerant system Refrigerant System Evacuate.
9. Recharge the refrigerant system Refrigerant System Charge.
