Rattling around the belt area can cause pumps to not spin well, which would run temps high plenty quick, AND could interfere with the P/S pump.
When I took my 2008 F-350 in for service early 2009 with about 35000 miles on it I asked them to look at or test P/S pump,, it was whining like Ford pumps do before they fail, and they had it for 3 days to remove all the radiators (6, 7, some number like that) to get to the pump which was failing. They also replaced one radiator cause it had a pin hole.
So your pump could be dying too, Ford P/S pumps die young and often. You can stand on a street corner with your eyes closed and pick out Fords from the P/S whine sound. Been that way for years, sometimes they whine for years without failing, too. Arrrgggh!
PS: all that work was warranted; I hate to think what it would cost after that's gone.
