1995 Dodge 2500 4x4 Ram 5.9 Diesel. My temp gauge just started to cycle up and down, between around 150 to 180 degrees. This happened about 4 years ago--I fixed it with a new thermostat. This time I put a new thermostat in, but the problem continues (it moves back and forth between 150 to 190 degrees now, so changing the thermostat did affect the symptoms.) Before failure, the temp stayed rock-solid around 170 degrees.
I still believe that it's the thermostat, maybe I just got a bad one? At $30 bucks a copy, I don't want to keep changing this part until the problem goes away.
Anything else that could cause this kind of problem that I've missed?
Thanks for your help.

Check with the Turbo Diesel Register. This was considered "normal" buy Dodge and Cummins although I don't see how all of those thermal cycles could be good for the engine. I thought they came up with a thermostat that didn't do that. Sounds like you got one of the old t'stats..
Thanks for the info. I've not heard of the Turbo Diesel Register. Is this available online?
I agree, I don't think that flushing cold water through a hot engine every 5 minutes is good either. Funny, even the off-brand Stant thermonstat had the same symptoms. I put a new Cummins unit it (from Dodge), and it behaves MUCH better, but not as steady as it was a few weeks ago. I wonder if the Cummins Dealer has a better price than Dodge....
Thanks again,
Michael
