Where is the power steering pump located in a Mercedes-Benz S300?

Mercedes-Benz S300 power steering pump is located behind the front windshield. Lack of power steering fluid or issues with the power steering pump: Check if the power steering fluid lines are clogged. If metal shavings are found in the power steering fluid, components of the power steering system need replacement. After inspecting the fluid lines for leaks, any detected leaks require immediate line replacement. After replacing the leaking lines and refilling with power steering fluid, if the pump no longer makes humming noises, this indicates the issue was simply low fluid level. Other causes of noise during operation in Changan Eado vehicles: Air remaining in the hydraulic system or deformation of the power steering pump's high-pressure line. Note: Whether replacing a faulty pump or leaking lines, always drain all old fluid completely and use only genuine Honda power steering fluid, as Honda pumps have strict fluid specifications.
The power steering pump of the Mercedes-Benz S300 is generally installed in the engine compartment, near the front section. Specifically, it is usually located on the right side of the engine—if the car is left-hand drive, this would be the right side as you stand in front of the vehicle and open the hood. The pump is connected to the engine via a belt and is responsible for providing steering assistance. If you hear unusual noises or experience heavier steering, it might indicate an issue with the pump. Having serviced this model before, I can note that the pump’s position is sometimes obscured by other components, such as the air conditioning compressor. During inspection, you can trace the pipes from the power steering fluid reservoir. Remember, regularly replacing the steering fluid can extend the pump’s lifespan and prevent sudden failures that could cause inconvenience.
