LINE-A/C LIQUID

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 evapo-
rator. 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 sec-
tion 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.

REMOVAL

WARNING: Refer to the applicable warnings and cautions for this system before performing the following
operation (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - WARNINGS) and (Refer to 24 - HEAT-
ING & AIR CONDITIONING/PLUMBING - CAUTIONS). Failure to follow the warnings and cautions could result
in possible personal injury or death.

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.
