Product Details

This power steering reservoir is a direct replacement for the original remote reservoir used on select Acura MDX applications. It is intended to address reservoir-related issues such as cracked housings, contaminated fluid, or restricted flow that can be mistaken for pump failure. The Cardone 3R-211 is also suitable as part of a full power steering pump service when the reservoir needs replacement at the same time.

This part cross-references Acura 53701STXA03 for the same application.

Common Issues It May Solve

• Power steering fluid leaks from a cracked reservoir body
• Foaming fluid caused by trapped air or restricted reservoir flow
• Noise related to contaminated or aerated power steering fluid
• Pressure loss caused by a clogged remote reservoir
• Heat-related plastic deterioration in the engine compartment

Installation Notes and Tips

Fits 2007-2013 Acura MDX, N/A. On these vehicles, the reservoir may be mounted on the firewall, inner fender, or near the power steering pump depending on configuration. Inspect the return and outlet hoses for cracking, debris, or internal breakdown before installation. If the fluid is foaming, bleed air from the system after service to prevent cavitation and pump damage.

For best results, verify hose condition and fluid quality during replacement. If the fluid is dark, gray, or contains debris, service the system according to the vehicle-specific OE procedure.

Quality Assurance

Cardone manufactures this reservoir to OE design standards and tests each unit to confirm proper fit and function. The reservoir is built from OE-grade material and is engineered to resist cracking in high-temperature engine bay conditions.
