The A/C suction line (1) is the refrigerant line that carries refrigerant from the A/C evaporator to the A/C compressor. The A/C suction line and is
secured to the A/C expansion valve by a tapping plate (2) and contains the low-side service port (3) and a heat shield (4), depending on engine
application.
NOTE: Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is opened. Failure to replace the rubber O-ring
seals and metal gaskets could result in a refrigerant system leak.
The A/C suction line has no serviceable parts except for the rubber O-ring seals, metal gasket and the low-side service port valve and its protective cap.
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 and gasket must be
replaced whenever the A/C suction line is removed and installed.
The A/C suction line cannot be repaired and must be replaced if leaking or damaged.
