Atlantic Automotive Enterprises RES-0042 Power Steering Reservoir

Power Steering Reservoir Overview

Atlantic Automotive Enterprises RES-0042 is an application-specific power steering reservoir built as a direct replacement for the original unit. It includes the reservoir and reservoir cap, making it a practical choice when servicing a failed steering pump or rack on select Mercedes-Benz models.

Key Features

• Direct replacement that fits and functions like original equipment
• Complete assembly includes the reservoir and reservoir cap
• Application-specific design for confirmed vehicle fitment
• Helps maintain proper hydraulic fluid flow in the steering system
• Supports cleaner service work when replacing steering components

Detailed Description

This hydraulic steering fluid reservoir is intended for Mercedes-Benz C250, C300, C350, C230, C280, CLK350, E280, E300, E350, E550, GLK350, and S550 applications listed below. The RES-0042 is a direct OE-style replacement for part number 0004602383 and is used to restore proper fluid storage and delivery in the power steering system. When a reservoir is cracked, damaged, or contaminated, replacing it during pump or rack service helps reduce debris-related wear and helps prevent air intrusion that can create steering noise and premature component failure.

This part cross-references 0004602383 for the same application.

What It Helps Address

• Cracked or damaged steering fluid reservoir housing
• Air entering the hydraulic system and causing steering noise
• Restricted fluid flow that can accelerate steering component wear
• Contamination left behind after a failed pump or rack
• Need for a reservoir replacement during power steering service

Installation Notes and Tips

Flush the power steering system before installing the replacement reservoir, especially after pump or rack failure. Inspect hoses, clamps, and surrounding steering components for contamination or wear before reassembly. Verify VIN-specific notes for 2006 Mercedes-Benz C230, C280, and C350 applications, since build location and VIN breakpoints affect fitment.
