The power steering fluid reservoir on a 1990 Chevrolet Caprice Classic V8 is typically located
on the driver's side of the engine compartment, near the firewall. It's usually a plastic reservoir with a cap that's clearly marked "Power Steering Fluid" or has a steering wheel symbol. Look for a relatively small reservoir that's somewhat cylindrical or rectangular in shape.
It's best to consult your owner's manual for the exact location and type of fluid to use. If you don't have the manual, a quick online search for "1990 Chevy Caprice power steering fluid reservoir location" with images might help you locate it visually. Remember to add fluid *only* when the engine is off and the reservoir is cold.
