Overheating or just overworked
I'm on my way back up to AK. Bad time to be pulling 10,000 lbs through the Midwest and over the Rockys HOT HOT So it is no suprise that the truck keeps overheating. However even in the morning when it is cool 69 like this morning in Utah it overheated. What can I do about it? Am I just overworking it? Is my ATS turbo causing the overheating? Would it help putting a 4in exhaust on? I know it would help cool the turbo which needs help I can't use all my power because the EGT gets way high. It is frustrating having more power available but unable use it. By the way if any one needs proof this trip has proved the 7.3 is bulletproof or at least idiot proof.

When you say overheating, is it water temp or exhaust temp? In either case (both) it is the way a diesel runs. It's common to have to back off the throttle in warm weather when pulling hills. Depending on how much it's turned up, how it's tuned, quality of the fuel ect. factors in with how hard you can push the engine.
Unless you have blown a hose or have some other water leak, when a diesel gets hot you let it idle to cool down. If you have wind in your face you can pull over and let it idle, otherwise kick the rpm up a bit to help with water circulation.
We have been over 100 degrees in Utah for the past several days and the surrounding states are not much better. The weight you have, plus some pretty good pulls, add the high ambient temp and it's the perfect receipe for light footing the throttle.
