Thanks Ben. I've been messing with this truck for a bit and I found something that to me is interesting. This is when I drive unloaded as in no trailer and only me in the truck. If I drive the freeways the temperature stays low around 160. But if I drive around town with all stop and go traffic lights, the temp climbs to almost 200 and stays there. So to me this means either my fan clutch is going, or my radiator has no real cooler built in. I think my first and cheapest move it to pull the lower coolant hose and see if I can find a way to look in the tank at the cooler.
