However, the exact location can vary slightly depending on specific trim levels and options. The best way to locate it is to:
1. Consult your owner's manual: This is the most reliable source for the location of all fluids in your specific vehicle.
2. Look closely in the driver's side engine bay: Systematically scan the area near the firewall, looking for a small reservoir with a dipstick or markings indicating power steering fluid level.
3. Use an online image search: Search for "1999 Chevy Lumina 3.1 power steering reservoir" to see pictures of the location on similar vehicles. This can be helpful to get a visual idea.
Remember to always check your fluid levels when the engine is cold and off.
