How do you put on an alternator belt to an 1992 S10 Chevy blazer?

96 grand Cherokee doesnt have a fan belt, its a serpentine belt. And if you look down to the right of the fan there is a pully which acts as the tensioner, youll use a socket to loosen it up and then youll be able to slide the old belt off. Keep the box from the new belt so you can see how the new belt loops around each pulley. Be sure to tighten the belt pretty tight so it has minimal play or youll get some sqeaking whenever you run your AC.
