Diagram/instructions Replacing belt on 2001 Chevy Cavalier?

[MIKE M]

Belt came off want to put back on. 93k miles. Belt not broke.

[Scott R]

Belt likely stretched. Belt pullys likely near death.

You put old belt back on, belt likely to come off again.
Maybe break something expensive. Maybe leave you walking.

Autozone.com have a repair section tell you how.
