Where is the power steering reservoir for 93 astro van?

The power steering fluid reservoir on a 1993 Chevrolet Astro van is typically located on the driver's side of the engine compartment, near the firewall. It's usually a small, plastic reservoir with a cap. It might be somewhat hidden depending on other components in the engine bay. Look for a reservoir with markings indicating "power steering fluid." A dipstick or a clear side might be present to check the fluid level.
