Hose/Line HVAC: Service and Repair
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 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 system See: Heating and Air Conditioning/Service and Repair/Refrigerant Oil Level.
NOTE: Replacement of the refrigerant line seals and gaskets is required anytime a refrigerant line is disconnected. Failure to replace the
rubber O-ring seals, metal gaskets or washer seals may result in a refrigerant system leak.
NOTE: The A/C liquid line is serviced in two sections. The front section connects between the A/C condenser and the A/C receiver/drier. The
rear section connects between the A/C receiver/drier and the A/C expansion valve. On models equipped with the rear heating-A/C
system, the rear section of the A/C liquid line also includes an extension tube that connects the liquid line to the underbody lines.
FRONT SECTION
1. Remove the tape or plugs from the opened refrigerant line fittings and the condenser and receiver/drier ports.
2. Lubricate a new rubber O-ring seal with clean refrigerant oil and install it and a new gasket onto the liquid line fitting. Use only the specified
O-ring seal as it 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 front section of the A/C liquid line (3) into the engine compartment and engage the liquid line to the retaining clip located near the
right frame rail.
4. Connect the front section of the A/C liquid line to the condenser tapping block (2).
5. Install the nut (1) that secures the front section of the A/C liquid line to the A/C condenser. Tighten the nut to 23 Nm (17 ft. lbs.).
6. Lubricate a new rubber O-ring seal with clean refrigerant oil and install it onto the liquid line fitting. Use only the specified O-ring seal as it is
