DODGE RAM SRT-10 2006 Service Repair Manual LINE-A/C DISCHARGE
DESCRIPTION
The A/C discharge line is the refrigerant line that goes from the A/C compressor to the A/C condenser and has an
integral fitting for the A/C pressure transducer (Refer

LINE-A/C DISCHARGE
DESCRIPTION
The A/C discharge line is the refrigerant line that goes from the A/C compressor to the A/C condenser and has an
integral fitting for the A/C pressure transducer (Refer to 24 - HEATING & AIR CONDITIONING/CONTROLS/TRANS-
DUCER-A/C PRESSURE - DESCRIPTION).
The A/C discharge line for the 5.9L Diesel engine is serviced as an assemblywith the suction 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 correct O-ring seal will cause the
refrigerant system connection to leak.
The A/C discharge line has no serviceable parts except the rubber O-ring seals. 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 discharge line is removed and installed.
If the A/C discharge line is found to be leaking or is damaged, it must be replaced.
