Where is the power steering reservoir on a 2007 Pontiac Grand Prix?

The power steering fluid reservoir on a 2007 Pontiac Grand Prix is located under the hood, on the driver's side (left side when facing the engine). It's usually a fairly easily visible plastic reservoir, often with a cap that's clearly marked "Power Steering Fluid" or has a corresponding symbol. However, the exact location might vary slightly depending on the engine. It's best to consult your owner's manual for a diagram to be absolutely sure.
