Try using a new belt buckle. The stretch in the belt is what makes it fly. It's like having a rubber band around your waist. Bend the clasp in a bit and it should cure the problem.
The force of Gravity.
It keeps the ecosystem from flying off the face of the planet
To change the serpentine belt on a 2004 Trailblazer, first, ensure the engine is off and cool. Locate the tensioner pulley and use a wrench to rotate it counterclockwise, which will relieve tension on the belt. Remove the old belt from the pulleys, then route the new belt according to the belt diagram usually found on a sticker under the hood. Finally, reapply tension by releasing the tensioner and double-check that the belt is properly aligned on all pulleys.

Fit a new belt tensioner
It keeps constant pressure on the belt so that it doesnt slip as it goes around the pulley's. It is also used for taking off and replacing the belt.
Replace belt tensioner. Three 13mm bolts in a triangular pattern, after you remove belt of course
Well, to tell the truth, everything inside a galaxy is actually flying off in space. Everything that is anything is flying off in space. Space is the thing that everything is in. What does tend to keep things together is gravity. So as things inside a galaxy are flying around in space, gravity keeps them from flying off in their own direction.
Gravity is what keeps objects in orbit around a planet from flying off into space. The gravitational pull between the planet and the objects creates a centripetal force that balances the outward motion, keeping them in a stable orbit.
Earths gravity keeps the moon from flying off in the same way the sun keeps earth in balance.
You either have a bad or loose pulley, a stretched belt or a tensioner that isn't working right.
Seems to be pretty logical, doesn't it?
