Overheat issue
I drive a 2004 Dodge Ram 4x4 with the 4.7L. Recently I was driving it in Texas (where it was consistently over 100 degrees), and I noticed that the truck was running anywhere between 3/4 hot on the gauge to just below the H. The cooler it was outside however, the cooler it ran. I changed the thermostat, had the radiator flushed, changed the temp transmittor, had the fan clutch replaced, and changed out the serpentine belt (the water pump isn't leaking/making noise/showing any signs of issues). I took it on a 1300 mile road trip where the outside temp never got higher that 70, and it ran great. Yesterday, however, I was driving it on the interstate with the outside temp around 85, and it the gauge started creeping towards 3/4 hot again...ideas?
