Suction 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 suction line is the refrigerant line that goes from the accumulator outlet port to the compressor inlet port. The suction line has no serviceable parts except the rubber O-rings. If the suction line is found to be leaking or is damaged, it must be replaced.
