Hose/Line HVAC: Description and Operation
Line-A/C Liquid
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 other using a spring-lock type refrigerant line coupler. 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.
