Engine problem
1997 Buick Riviera 6 cyl Front Wheel Drive Automatic 100000 miles

I need to find a engine diagram for a supercharged 3.8 liter engine, because I have a pulley almost wore out and need to replace it but I can't figure out which pulley I need by looking at the parts list at RockAuto. Com or OnlyFactoryParts. Com. There must be an illistrated parts list for that engine somewere, but where?

Thank you in advance.

Do you

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.
