Hose/Line HVAC: Description and Operation
Suction Line
DESCRIPTION
The A/C suction line is the refrigerant line that goes from the A/C evaporator to the A/C compressor. The A/C suction line is made from light-weight
aluminum tubing with braze-less and crimp type fittings and nylon tubes with rubber barrier hose See: Heating and Air Conditioning/Description and
Operation/Plumbing/Description .
The A/C suction line for the 5.9L and 6.7L diesel engines is serviced as an assembly with the A/C discharge line.
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 O-ring seals and the 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 A/C suction line is removed.
The A/C suction line cannot be repaired and must be replaced if found to be leaking or damaged.
