Where is the alternator located on a 1996 Pontiac Bonneville SE?

On a 1996 Pontiac Bonneville SE, the alternator is typically located at the front of the engine, on the passenger side. It's usually driven by a serpentine belt. However, to be absolutely certain, you should consult a repair manual specific to your vehicle's year and engine (e.g., a Haynes or Chilton manual). A diagram in the manual will show the exact location.
