1996 Dodge w/ Cummings
Greetings! Brand new here and I thought I would try out a question for some help. I have been experiencing, for a while now, water temp fluctuations. I have a 1996 Dodge with the 6 cylinder Cummings. I bought the truck new and it doesn't have any real modifications from factory. While driving, I am getting readings from 150 deg to 180 deg in about 2 minuets. I can go for 50 miles and it will be steady. Then, for no reason it moves up or down. I have had installed a new water pump, thermostat, fan clutch, sending unit, and two complete system flushes. What in the world is going on? Any advice is greatly appreciated.

So 3 hours of driving later, the gauge stays put.

Completely normal. As others have said, it's just the thermostat opening and closing.
In 1998 (IIRC) they changed that because people were concerned. If you ride in a newer one, you'll notice it doesn't fluctuate like that -- not because the temperature doesn't really fluctuate, but because it kind of dumbs it down -- takes an average if you will.
Basically, if it DOES NOT fluctuate, you might have an issue, otherwise you're fine.
