NOTE: LHD model shown. RHD model similar.

The A/C liquid line is the refrigerant line that carries refrigerant from the A/C condenser to the A/C evaporator. The A/C liquid line is serviced in two sections. The front section of the liquid line (1) connects to the rear section of the liquid line (5) with a nut (2) and includes the high side service port (8). The rear section of the A/C liquid line includes the fitting for the A/C pressure transducer (6) and a mounting bracket (7) and is secured to the A/C expansion valve by a tapping plate (4). The rear section of the A/C liquid line is serviced as an assembly with the rear section of the A/C suction line (3).

CAUTION: Use only seals specified for the vehicle. Failure to use the correct seals will cause the refrigerant system connections to leak.

The A/C liquid line has no serviceable parts except for the dual plane seals, high-side service port valve and it's protective cap. The seals used on the connections are made from a special type of rubber not affected by R-134a refrigerant. The seals must be replaced whenever the A/C liquid line is removed and installed.

If either section of the A/C liquid line is found to be leaking or damaged, it must be replaced.
