I have the same problem as well and was checking to see if you ever solved this issue, and if so, how???

My 2500 ram only does it when I tow my camper. Temp goes just above 200 then the light comes on never did this before they changed the transmission.

 

That's good to know. I have never heard my fan come on. My trailer is 15K lbs and I have pushed it. I never seem to overheat, but I think I remember it going slightly over 200 degrees once or twice but the fan never came on?
Sorry off subject a bit.
I had a car once that ran at 220-230, unknowingly, until I put a gauge on it. Had radiator cleaned out(full of corrosion) and she went back to 190.
Could be a possibility?

 

hey, my 2004 cummins rises to a temperature of 200 exact when im not towing anything, why is this? can anybody tell me what I can do to solve this problem?

 

200 is normal

 

Same subject but just different problem. I have a 2005 2500 with smarty (turned down to 3), straight piped, cold air intake, and southbend dual disk. While pulling anything I am getting pyro readings 1300-1400 during hill climbs. Of course I'm letting off at this temp and allowing truck to cool because this is at breaking/melting level. My boost at this time is running anywhere between 25-30 psi and all other gauges are reading fine. Any suggestions as to what this might be?

 

Normal temps POD at what Number? try 75 I run 1300 for long hill climbs! take it out of OD lets it breath better at higher RPM's! 1200 you can run all day long!
