Liquid Line: Description
WARNING: This page is about a different car, the 2004 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
The liquid line is the refrigerant line that carries refrigerant from the A/C condenser to the A/C evaporator. The liquid line is made from light-weight aluminum or steel, and has spring-lock coupler fittings on each end.
The liquid line contains the fixed A/C orifice tube and a fitting for the A/C pressure transducer and the high side service port. The liquid line is only serviced as an assembly, except for the rubber O-ring seals used on the fittings. The liquid line cannot be adjusted or repaired and, if found to be leaking or damaged, it must be replaced.
