Help! My coolant temp heats up fast in idle or slow-moving traffic (around 210F+) then decreases when I start driving (around 170F-190)

Water pump or fan clutch

Does the fan turn freely when the engine is cold? Or does it have a bit of resistance.

If the fan keeps spinning after you shut off the truck, then (as stated above) bad clutch.
