LINE-A/C SUCTION
DESCRIPTION
The A/C suction line is the refrigerant line that goes from the A/C evaporator to the A/C compressor.
TheA/Csuctionlineforthe5.9LDieselengineisservicedasanassemblywith the discharge line.
The A/C discharge line for the 8.3L engine is secured to the top of fan shroudby two retainers.
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 A/C suction line has no serviceable parts except for the rubber 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 refriger-
ant. The O-ring seals must be replaced whenever the A/C suction line is removed and installed.
If the A/C suction line is found to be leaking or is damaged, it must be replaced.
