However, the exact location can vary slightly depending on the engine type (V6 or V8). The best way to find it is to:
1. Consult your owner's manual: This is the most reliable source. The manual will have diagrams and specific instructions.
2. Look for a reservoir with a dipstick or markings: Scan the engine bay carefully, looking for a small container that fits this description. It's usually close to other fluid reservoirs.
3. Use an online image search: Search for "1997 Pontiac Bonneville power steering fluid reservoir" and look at pictures. This can help you visually locate it.
If you still can't find it after trying these steps, it's best to consult a mechanic.
