When the engine is running hot or overheating can you hear the cutch fan kick in? If not the first thing was needed to do is check fuse # 78 10-amp int he under hood fuse panel, this fuse controls the radiator electronic clutch fan, if that's okay the truck may need the electro fan clutch replaced, here are the instructions in the diagrams below plus a generic guide on what to look for when the truck is overheating.
I have also included the cooling fan wiring diagrams so you can see how the system works. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
