I have a 2007 Dodge Ram 2500 with a 5.9 diesel. When towing or in slow traffic, the temperature guage will spike and show overheating. It does not happen all of the time. Most times I can hear the howl of the clutch fan engaging. Could this be a clutch fan going bad or some other ECM problem?

So when its running too hot you cant always hear the fan clutch kicked in?Also when its running hot can you feel a lot air being pushed?With the engine shut off see if the fan clutch feels loose.

It does not do it all the time but when it does you cannot hear the fan and do not feel a lot of air. When shut off, the fan free wheels.

If its running hot and the fan spins freely and theres not alot of air you have a bad fan clutch.
