I have a 1996 Buick Riviera 3.8L, Supercharged.
A diagram for the pulley arrangement is in my owners manual. Most likely this would also apply to your 1997 Riviera.
You might be able to pull an original owners manual online.
Some of the cars have a decal under the hood showing this, but not on my riviera.
The other source of information would be Alldata web site for $25 per year subscription-well wo;rth it.
