if your belt is loose, the tensioner probably needs replacing. the tensioner is the mechanism that keeps the belt tight.
If your F350 has a serpentine belt it really can't be 'tightened'. The tensioner, located on the passenger side second pully down on a 7.3 PSD, is what provides the tension on the belt. If you are getting slack then it is probably time to replace the tensioner. If you are at all mechanically inclined it is a fairly easy task. Even if you are not and have a Haynes manual you can probably knock it out in a few hours.
Remove surpentine belt,then take out bolt that goes through tensioner to engine.
Use a tensioner tool or wrech if you can to pull the tensioner so the belt loosens. thread in the new belt and release the tensioner to tighten the belt. Belt diagram is usually in the engine compartment
Done automatically by belt tensioner
Should have a spring loaded belt tensioner
It is located right under the alternator.
Remove belt and tensioner complete should be able to be unbolted from engine (Left-hand thread)
you do not need a tool to tension pully belt if belt is loose, belt needs replacing tensioner works automatically
use tensioner to loosen belt. Using a socket, remove the old tensioner..put the new one on and if you were careful, you should be able to slip belt right back in place.
