I have a 2002 Dodge Durango SLT 4.7 that has been overheating. It overheats at Highway speeds about 60+ and then it cools down when I start to slow down. Also it overheats faster when I run the AC or the heat. I have already changed out my radiator twice as well as the upper radiator hose and cap. It is still showing this behavior. Any suggestions?

I currently am having the same issue. I have traced the issue back to the fans. The fans would not kick on so i let it run to almost overheating temperature, and checked the fans.... nothing was working. I slammed the hood to test a wild hair idea that one of the wires or the fans wasnt getting power. When i slammed the hood, The fans kicked on and the temp. dropped. So now its on to wire chasing.

First thing first, turn off the engine wait for 15 - 20 mints, open the radiator cap and fill it up to the top then start the engine and see if it needs more water adn add as needed, then wait till you ca see the water circulating in the radiator now instead of corculating if it starts boiling out shut the engine replace the thermostat and do the whole thing again.

unless there is water in the engine the gauge will not be able to show the actual temp of the engine, so always malke sure you have water / antifreeze

Dealer only place to get the whole 3 piece radiator hose assembly for problem you describe. Not bad price.I know this from my experience. Trust me I searched everywhere. T-stat located where diagram that was sent. $60.00 for part

Check thermostat. Must be stuck. Remove and replace.

is the a/c running or not??
if it is check to be sure the auxiliary fan comes on when you turn the a/c on!!!
if thats ok then it's probably your fan clutch!!!
