Dodge D350 ProblemsAir Conditioning Not Cold
The powertrain control module (PCM) may fail resulting in a lack of AC cooling. The lack of cooling could be caused by evaporator freeze-up due to the AC compressor staying on continuously or conversely, not coming on at all. Proper diagnoses of the PCM should be performed before replacing it for this concern.
The following cooling system components are prone to leaks: Thermostat housing gasket, water pump, heater tube o-ring at water pump housing, intake manifold gasket, and timing cover gasket. These are generally external, not internal coolant leaks so intermix with the engine oil in uncommon.
Under light load, at approximately 2000rpm the engine could exhibit surging, bucking, or intermittent misfires. Our technicians tell us this could be caused by a mis-indexed distributor.
