Oldsmobile/Buick Repair: putting new belt on 91 olds.van, grooved pulleys, gm car

Question
how do i put a new serpeitne belt on do you have a diagram?

Answer
Just about every GM car with a serpentine belt, has a diagram under the hood somewhere.
But without the diagram, just keep in mind that the smooth side of the belt goes against the smooth pulleys, and the grooved side goes against the grooved pulleys.
There is a spring loaded tensioner....just rotate it against the spring, and that's about it.

If you absolutely need a diagram, the public library, refference section has a manual that you can make a copy of your diagram.
