Where do you add the power steering fluid to a 1999 Pontiac Bonneville Sedan?

The power steering fluid reservoir on a 1999 Pontiac Bonneville is typically located under the hood, near the firewall, and often has a cap with a power steering symbol (a steering wheel). It's usually a translucent or clear plastic reservoir so you can see the fluid level.

However, always consult your owner's manual. The exact location and type of reservoir may vary slightly depending on specific engine options or other modifications. The owner's manual will have a diagram showing the location and will also tell you what type of power steering fluid to use.
