Detailed Description

The Cardone 3R-801 power steering reservoir is designed for Mercedes-Benz vehicles that use a remote-mounted reservoir instead of an integrated pump tank. It is a direct replacement for the original reservoir and is built to match OE dimensions and flow characteristics, including filtration efficiency on versions with an integrated filter. This part cross-references Mercedes-Benz 0004600183 for the same application.

What It Helps Address

• Low power steering fluid level from a cracked reservoir body
• Foaming fluid caused by trapped air in the steering system
• Noise or cavitation linked to restricted reservoir flow
• Leaks at the reservoir housing or hose tube connections
• Debris contamination from aging hoses and fluid breakdown

Installation Notes and Tips

On Mercedes-Benz power steering systems, the reservoir may be mounted on the firewall, inner fender, or near the pump. Inspect the return and outlet hoses during replacement, and bleed air from the system after installation to prevent foaming and noise. If the fluid is dark, gray, or contaminated, service the hoses and fluid at the same time.

Quality Assurance

Each Cardone 3R-801 reservoir is tested to confirm proper fit and function before it leaves the factory. The part is manufactured from OE-grade material and follows the original design for dependable service in remote-mounted power steering systems.
