Womala Engine Oil Cooler Assembly OE 1121800065 for Benz Engine Lubrication System Parts
The Power Steering Pump (OE: 0044668501) is a core component of the power steering system for Mercedes Benz W164 series ML models and W251 series R-Class models. Mounted on the engine, it converts mechanical power into hydraulic pressure to assist steering, reducing driver effort. As an OE-grade part, it meets Mercedes Benz’s strict standards for pressure stability, hydraulic efficiency, and durability, ensuring reliable operation across conditions (e.g., low-speed maneuvering, long-distance driving, extreme temperatures).
Constructed from high-performance materials: the pump housing uses high-strength aluminum alloy (for lightweight and corrosion resistance), while internal rotors and seals are made of wear-resistant materials to withstand high hydraulic pressure. Precision machining ensures minimal fluid leakage and consistent pressure output.
Core Functions
Hydraulic Power Supply: The primary function is to generate stable hydraulic pressure, reducing the force required to turn the steering wheel and improving driving comfort.
Steering Responsiveness: Delivers instant hydraulic assistance during steering operations, ensuring smooth and precise control of the vehicle.
System Protection: Built-in pressure relief valves prevent overpressure damage to the steering system, extending the lifespan of hoses, racks, and other components.
Compatible Vehicles
This Power Steering Pump is tailored for the following Mercedes Benz models and its respective OE number:

Notes: This Power Steering Pump is model-specific and designed exclusively for the listed Mercedes Benz models. Do not use it for other models or variants to avoid insufficient steering assistance, hydraulic leakage, or system malfunctions. During installation, ensure proper alignment with the engine pulley and tight connection of hydraulic hoses. Use only Mercedes-approved power steering fluid to maintain performance. Periodically check for fluid leaks, abnormal noise during operation, or stiff steering, and replace immediately if faulty to ensure safe and smooth driving.
