Product Details

The Cardone 3R-123 power steering reservoir is designed for vehicles that use a remote reservoir rather than a pump-mounted tank. It follows OE fit, function, and performance requirements, and it is manufactured from OE-grade material to maintain proper fluid storage and system operation. For Toyota Sienna models from 2004 through 2010, this reservoir provides a direct replacement option when the original unit is cracked, leaking, or contaminated. Cardone 3R-123 is also a practical choice when replacing a pump and reservoir together during a complete steering service.

This part cross-references Toyota 4436008020 for the same application.

Common Problems This Part Can Address

• Power steering fluid leaks from a cracked reservoir body
• Foaming fluid caused by air entering the steering system
• Noise from a restricted or contaminated remote reservoir
• Loss of proper fluid storage after heat-related plastic damage
• Service issues during a power steering pump replacement on a Toyota Sienna

Installation Notes and Tips

On many vehicles, the reservoir is mounted on the firewall, inner fender, or near the power steering pump. Before installation, inspect the return and outlet hoses for cracking, debris, or internal breakdown, since hose condition can affect fluid quality and reservoir performance. If the fluid is foaming, bleed the system to remove trapped air after installation. Verify the reservoir location and hose routing against the vehicle-specific service manual for the 2004-2010 Toyota Sienna.
