This is a link to the serpentine belt routing diagram that worked for my '04 Pontiac Vibe. As far as I know, this is the routing for all Pontiac vibe base and GT models. http://forums.genvibe.com/zerofile/1436belt.jpg
How do you change the supercharger belt tensioner in 1997 Pontiac Grand Prix GTP?

By wearing your seat belt.
The 1.8 liter four cylinder in a 2003 Pontiac Vibe has a timing CHAIN
what size engine
Assuming you're asking about the serpentine belt, you cannot adjust the tension. If the belt is too loose it's either because it needs to be replaced or the belt tensioner needs to be replaced.
Remove the serpentine belt. Tensioner is below Alternator. Remove the three mounting bolts on the tensioner baracket assembly. Replace entire unit.
I've been informed it has a timing chain, not belt, and therefore does not need to be replaced.
To change the serpentine belt on a 2003 Pontiac Bonneville, loosen the tensioner pulley and remove the old belt. The tensioner pulley is the wheel in the belt system that has a bolt through the middle in a slot that can be adjusted. Put the new belt on and tighten up the pulley.
The system that the belt runs on ,is called a serpentine system,it's a one belt set-up ,and they are self adjusted by a tensioner,sounds like...1- Your tensioner is seized,or ..2-your belt is streched..Sometimes the tensioner can be free'd by taking it of and working it in with lubrication,but if not,get a new tensioner and a belt, hope it helps.
Fasten your seat belt or live with it, it will stop after a few moments.
