Where is the alternator in a 1995 Olds Cutlass Supreme?

The alternator will be circular with slits cut in them for heat vents. You might be able to see the copper in them too. It most likely is on the opposite side of the compressor, if not below it. The alternator on a '95 Cutlass Supreme with a 3.1 Liter V6 is located at the left hand side of the engine bay near the firewall. It is right on top and easily accessable. However, if you don't know what an alternator looks like, I wouldn't recommend trying to fix it without some help from someone who knows what they're doing. Its a little tricky to remove. The bottom "Pivot" bolt is 13 mm on the outside but the nut on the othe side is difficult to reach and it is a 15mm . I used a 15mm socket with about 12" of extension to reach it. There is also a brace that runs from the Valve cover to the base of the backside of the alternator . It not that overwhelming, but just takes a little time and patience to mess with that 15mm nut on the pivot bolt.
