Key Features

• Resistant to cracking and wear from repeated heat cycles to help prevent power steering fluid loss
• Produced from virgin plastic to meet or exceed OE material specifications
• Direct-fit design supports straightforward installation
• Manufactured to strict engineering standards for materials and tolerances
• OE-quality replacement for Mercedes-Benz power steering systems

Detailed Description

Rein PSR0022 is a replacement power steering reservoir designed for a wide range of Mercedes-Benz vehicles, including G55 AMG, ML500, E500, CLK500, and S430 applications. Its application-specific design helps maintain proper fluid storage and system function while matching the original reservoir’s fitment requirements. This part cross-references URO 0004600183 for the same application.

By using virgin plastic instead of regrind material, the reservoir is built to better withstand the thermal cycling common in engine-bay environments. That construction helps reduce cracking over time and supports long service life in daily-driven and performance-oriented Mercedes-Benz models.

What It Helps Fix

• Cracked or brittle power steering reservoir housing
• Power steering fluid leaks from heat-damaged plastic
• Low fluid level caused by reservoir seepage
• Reservoir replacement during steering system service
• Fitment issues from worn or incorrect aftermarket parts
