ok so i was just pulling onto the street and i hear this loud squeal had no brakes and no steering so i shut the truck off and after i got my friend to start the truck i noticed the crank spins but the belt doesn't move I'm thinking the fan clutch is seized there is a code for it also.
You had an idler or tensioner pulley fail. Been there, done that... around 65k I think, I will check my records if you care. Now I replace this stuff every 50k, belts included.
Buy two
Ford tensioners, aftermarket are all full of Chinese crap bearings. Same goes for the idlers. I picked this up from Sunrise Ford?, one of the sponsors here.
I run the Gates 'green' belts, but Ford work well too.
