2500hd overheating
ive got a 2500hd with 05+efans that is overheating sometimes. its fine around town, but when i was on a road trip it was about 105 out and cruising at about 85 mph it would get up to about 235 with the a/c on pulling grades (anytime rpms were up really) i didnt notice this at all last summer. now we just picked up a camper the weighs about 6000 lbs and it will get hot 235-240 when pulling grades and it was only 75 out. i have a larger trans cooler as well and it stays about 125 until engine temp gets hot then it gets up to about 200.
i replaced the thermostat and the temp sensor. water pump is about a year or so old NAPA unit. only thing i can thing of really is maybe the radiator is plugged? or partially? i tow alot in the winter and never overheats but its also below freezing most of the time.
any ideas/suggestions? ive cleaned the fins of the radiator and condenser, deffinatly air traveling through. it will cool down if i pull over and idle for about 5 min but heats back up til im off the grade
