Here's the deal, i have a 2010 dodge Ram 2500 diesel. It just starting today overheating. It would range from 203 degrees to 224 degrees. When i got on it going up a hill, the temp climbed to 245 degrees and i got a alarm. Normally the engine temp runs at 203-204 degrees. I need help figuring this out before i pull my trailer.

Mods: H&S mini max, 5 in exhaust turbo back, EGR deletes, AFE cold air intake, H&S intake manifold

 

First I would check airflow, make sure the rad, coolers are not full of bugs and stuff, a little degreaser and a good garden hose can sometimes clean out the crap. If not you should still be on warranty.

 

How long have you been deleted?

It sounds like you have air trapped in your coolant system. You might want to try bleeding the system again...

 

I've been deleted for over a year. I changed out the radiator cap. Seems to be working now, but coolant temp fluctuates between 201 and 212. So i don't know if i still have a problem.
