OK thank you so much. The reason I ask is because I thought my 1997 Bonneville serpentine would be a garage change like my 1992 Bonneville. But I found out the hard way. I had to remove engine mount bolts and lift the engine up with a floor jack and slide the belt underneath the left side motor mount. Which was a ***** on my own but I would say that was an 9/10 if you have the tools to do it and if you don't have a good stock of tools in your garage it would be a mechanic replacement. That's why I asked just because I remember the day of the 97 Bonneville. Thank you all so much.
