A/C Liquid Line - Installation

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, see 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 and gaskets is required anytime a refrigerant line is disconnected. Failure to replace the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.

NOTE: 3.8L engine shown in illustrations. 2.8L engine similar.





1. Position the A/C liquid line (1) into the engine compartment.
2. Remove the tape or plugs from the opened suction and liquid line fittings and the condenser and expansion valve ports.
3. Lubricate a new rubber O-ring seals with clean refrigerant oil and install them and a new gasket onto the suction and liquid line fittings. Use only the specified O-ring seals 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.
4. Connect the A/C liquid line to the A/C condenser (3) and install the retaining nut (2). Tighten the nut to 23 Nm (17 ft. lbs.).





5. If removed, install the A/C liquid line (3) into the tapping block of the A/C suction line (5).
6. On 2.8L equipped models, connect the air intake hose to the throttle body.
7. Connect the A/C liquid line and A/C suction line to the A/C expansion valve (1) and install the retaining nut (2). Tighten the nut to 8 Nm (70 in. lbs.).
8. If removed, install the bracket (4) that secures the A/C liquid line to the A/C suction line.
9. Reconnect the negative battery cable.
10. Evacuate the refrigerant system Refrigerant System Evacuate.
11. Adjust the refrigerant oil level Refrigerant Oil Level.
12. Charge the refrigerant system Refrigerant System Charge.
