INSTALLATION
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system See: 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: 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: The A/C liquid line is serviced in two sections. The rear section of the liquid line is serviced as an assembly with the rear section of the
A/C suction line.
FRONT SECTION
NOTE: LHD model shown. RHD model similar.
1. Position the front section of the liquid line (2) into the engine compartment.
2. Remove the tape or plugs from the fittings that connect the front section of the A/C liquid line to the rear section of the A/C liquid line (3).
3. Lubricate a new dual plane seal with clean refrigerant oil and install it onto the liquid line fitting. Use only the specified seal 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.
4. Connect the front section of the A/C liquid line to the rear section of the A/C liquid line.
5. Install the nut (1) that secures the front section of the A/C liquid line to the rear section of the A/C liquid line. Tighten the nut to 22 Nm (16 ft.
