A/C Liquid Line - Installation
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 Capacity . 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 See: Heating and Air Conditioning/Service and Repair/Refrigerant Oil Capacity .
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.
1. Position the A/C liquid line (2) into the engine compartment and engage the liquid line to the two retaining clips (1). Make sure the retaining clips
are fully engaged.
2. Remove the tape or plugs from the opened refrigerant line fittings and expansion valve ports.
3. Lubricate new O-ring seals with clean refrigerant oil and install them onto the refrigerant 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 (2) and A/C suction line (3) to the A/C expansion valve (4).
5. Install the nut (1) that secures the A/C liquid and suction lines to the A/C expansion valve. Tighten the nut to 23 Nm (17 ft. lbs.).
