LINE-A/C LIQUID
DESCRIPTION
The liquid line is the refrigerant line that carries refrigerant from the A/C condenser to the A/C evaporator. The liquid
line for this model consist of two separate lines that connect to each otherusing a spring-lock type refrigerant line
coupler (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING/REFRIGERANT LINE COUPLER - DESCRIP-
TION). The liquid lines are made from light-weight aluminum, and use braze-less fittings.
The front half of the liquid line includes the high-side service port and the rear half of the liquid line contains the
fixed orifice tube.
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 liquid line has no serviceable parts except for the rubber O-ring seals, high-side service port valve, cap and
secondary retaining clip. 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 liquid line is removed and installed.
If the liquid line is found to be leaking or is damaged, it must be replaced.
