Where is power steering oil container in Chevy venture van?

The Chevy Venture doesn't have a separate power steering fluid reservoir that looks like a container with a dipstick like you might find in an engine oil reservoir. The power steering fluid reservoir is integrated into the power steering pump itself. You'll find it on the passenger side of the engine compartment, typically attached to the power steering pump. It's usually a small reservoir with a cap on top. Look for a cap that might be labeled "Power Steering Fluid" or have a power steering pump symbol.
