Can you hear the fan lockup?

Don't really hear anything different.

Fan clutch is shot.
Running empty is no big deal. I ran without a fan for half a year, no overheating. But no towing either.

Going to change water pump and clutch and see what happens

Going that far get a new thermostat. Motorcraft is the recommended brand. Get the standard temp, not the 205°F.

New thermostat new pump new fan clutch. Still heating up pulling trailer over 60 mph. 7100lbs trailer

Otherwise seems to have good power?
Maybe the radiator is clogged? I know mine was pretty nasty when I hosed it out.

Pull the rad, use some coil cleaner and blow out the fins.

"overheating" according to the dash gauge or actual coolant temp.....what is your coolant temp when "overheating" ?
