Goodmorning,
I have a 2011 ram 2500, 194,000 egr deleted with an h&s mini maxx tuner. The tuner is set mild for all the tunes. i also have ARP 625 head studs. Just wanting to lay all that out there before I get to my problem. So I didn't drive my truck for a while, i have a gas burner i was daily driving and recently sold for wanting to get a second deisel. well I started driving the cummins again and it has time where the temp will momentarily shoot up to about 220-230, hang out at those temps for a few seconds and come back down. the programmer drops the truck back to the stock tune as well. I initially thought it could be a bad thermostat. swapped it no issues. hooked up to my fifth wheel made it 20 mins up the road and the truck shot up to 240 and stayed pulled off. the truck cooled after turning off. tried one more time to get going after letting it cool didn't make it 100 yards got hot. un-hooked the camper and got my buddy to grab it. I pulled the water pump all looks good. filled coolant back up. burped the system then noticed the lower radiator hose was collapsed. My mechanic that taught me said it was a clogged radiator, so i replaced it and the hoses. Well it did the momentary overheat again this morning. I am draining all mixed coolant this evening and going with straight uncut coolant. Any input will be much appreciated, trying to iron out all issues before I have to drag the camper 800 miles to ohio for work.
