Does the top of the radiator or area around the cap get hot?

I'm not sure why, but the radiator water level may have something to do with it. If the truck is not overheating and level is down, there's not water getting to it.
These trucks, for the most part, run a few inches below the top unless you have an overflow tank that keeps the level full..
