A/C ON TRUCK HEATS UP?
 

so this weekend i was on my way back home from hunting and had the a/c for about an 1hr then truck started to get hot, I turned off a/c and temp went back to normal. what could this be?

things i have done all newer
egr delete
all injectors
standpipes, plugs
oil cooler

1 of 2 things come to mind, low coolant, or a problem with the ac pump.
How long was the ac off?
How often do you use the ac? I mean, you have an 05, but do you use it a lot? May just need a re-charge. Start with the basics.

Did I mean engine temp went up??

Pretty much screwed the pooch on that one, my reading and comprehension skills SUCK sometimes.:argh:

That being said, how much coolant is in the truck? Have you plugged in a code reader? Define hot and normal.

Going to need some more info here...
