A/C Liquid Line - Description
DESCRIPTION
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).
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.
The A/C liquid line has no serviceable parts except for the dual plane seals, high-side service port valve and its 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
disconnected.
The A/C liquid lines cannot be repaired and must be replaced if leaking or damaged.
