There are many people pointing to the fan clutch. The easiest way to check if you are getting proper air flow through the radiator is to warm up the engine to normal with the hood closed and lay a shop towel over the grill. If the towel will not stay put that means the fan will not pull the air the engine needs at idle. If the air flow is adequate then the radiator is suspect for your issue.
Another Old School Mechanical/Temp Activated Fan Clutch Performance Test
Bring truck up to operating temperature.
Fold over an old section of 5/8" heater hose so it's about a foot long when doubled over.
With engine idling, and being aware of engine compartment surroundings, carefully insert the folded over hose in the path of the fan blades.
If the clutch is good, it will easily overcome the resistance of the heater hose, and act like it's a playing card on bicycle wheel spokes.
If the clutch is bad, the fan will instantly stop spinning as the engine continues to idle.
