DESCRIPTION
NOTE: 4.7L engine shown in illustration. 3.7L and 5.7L engines similar.
The A/C liquid line (1) is the refrigerant line that carries refrigerant from the receiver/drier (5) to the A/C expansion valve (2). The liquid line is retained
to the A/C expansion valve by a tapping plate (3) which is integral to the A/C suction line (4). Models equipped with the rear heating-A/C system include
an extension tube (6) that connect the liquid line to the underbody liquid line (7) by use of a tapping block (8).
CAUTION: Use only O-ring seals specified for the vehicle. Failure to use the correct O-ring seal will cause the refrigerant system connections to leak.
The A/C liquid line has no serviceable parts except for the rubber O-ring seals. The O-ring seals used on the connections are made from a special type of
rubber not affected by R-134a refrigerant. The O-ring seals must be replaced whenever the A/C liquid line is removed and installed. If the A/C liquid line
is found to be leaking or is damaged, it must be replaced.
