I have a 1999 Chevy Tracker I have had to replace my belt on my car 3 times within a week why does it keep breaking I had my alternator checked and it's good

SOURCE: Problem with Altenator belts Etude

the problem is not the altenator. you should have a idler pully and a self adjusting idler tensioner. if thes e go bad the bearings tend to seize up and break belts i would check these first chance you get the tensioner should be spring like and be hard to move back and forth the pulley part of it should spin freely with out makeing a noise. please rate this

SOURCE: altenator belt breaking

Is this a single serpentine belt system or a V belt with 2 or more belts running the accessories? There is an alignment issue, another bad accessorie or bad bearing (quite possibley the new alt) or as mentioned a bad idler ( if a serpentine belt setup)

SOURCE: How do you relace an alternator belt on 1998 chevy tracker?

A year is not a good sign. The belt should not have come off in that span of time. I would make sure you do not have a worn out idler or tensioner pulley bearing before installing your new belt or reinstalling the original if it is not worn or damaged.

You will find one or two small pulleys involved with drive belt. One of the smaller pulleys will be an "idler" pulley and simply redirects the belt to a different accessory. The other small pulley is considered a "tensioner" pulley, it is spring loaded and keeps the correct tension on the accessory belt.
The tensioner pulley will have a "squared" hole in the bracket or a bolt through the center of the pulley. In either case you will use a wrench to pry the tensioner pulley arm in the direction that loosens the belt. Once tension is relieved, pull the belt off a pulley and remove the belt. You will reverse the process to install the new belt.
Good luck and let me know.
Regards,
