INSTALLATION
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system See: Heating and Air Conditioning/Service
and Repair/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 systemSee: Heating and Air Conditioning/Service and Repair/Refrigerant 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.
NOTE: 4.7L engine shown. Other engines similar.
1. Remove the tape or plugs from the opened refrigerant line fittings and expansion valve and compressor ports.
2. Position the A/C suction line (2) into the engine compartment and install it to the front A/C expansion valve (1) and the A/C compressor (3) See:
A/C Line - Installation.
3. Raise and support the vehicle.
4. Lubricate a new rubber O-ring seal with clean refrigerant oil and install it onto the underbody suction line fitting. Use only the specified O-ring as
it is 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.
5. Connect the suction line extension tube (4) to the underbody suction line (6) and install the nut (5). Tighten the nut to 20 Nm (15 ft. lbs.).
