Purpose and function in the steering system

The offered set of hoses is a component of the hydraulic power steering system, connecting the steering gear to other system components. It is responsible for:

• transporting the working fluid at the appropriate pressure,
• maintaining the tightness of the power steering circuit,
• stable operation of the steering rack throughout the full steering range,
• reducing pressure drops and unwanted vibrations in the system.

Thanks to the proper fitment for the specific OM642 engine version, the hoses maintain the correct routing in the engine bay, which minimizes the risk of rubbing, overheating, or incorrect positioning relative to other components.

Construction of the power steering hose set

The set includes rigid pipes and flexible hose sections, designed to work with the steering gear in the Mercedes ML W164. The applied design solutions ensure:

• appropriate internal diameter for fluid flow,
• optimized geometry of bends and profiles,
• adaptation to operating pressures typical for power steering systems,
• stable mounting at factory attachment points.

A hose set configured in this way allows for maintaining the integrity of the entire power steering system and reduces the risk of leaks resulting from the incorrect selection of universal replacements.

Benefits of using original hoses in the Mercedes ML W164

Selecting hoses dedicated to a specific model and engine unit translates into a number of practical advantages:

• Precise fitment – the hoses are routed according to the factory layout, without the need for modifications.
• Reduced risk of leaks – proper ends and connectors reduce the possibility of leaks at the joints.
• Stable system operation – correct fluid flow supports the uniform operation of the steering gear.
• Diagnostic support – clear assignment to a specific configuration facilitates part identification in the workshop.

This solution is particularly beneficial when repairing vehicles that are used intensively or have high mileage, where the power steering system is exposed to wear of hoses and connectors.

Component condition and service application

The offered power steering hose set is an item from the Power Steering Hoses category intended for service applications in Mercedes vehicles. It works well both when replacing damaged or corroded hoses and during comprehensive steering system maintenance, including the gear, pump, and other hydraulic components. The correct selection of this element allows for restoring proper power steering operation without interfering with the vehicle's construction.

Complementary elements and seasonal preparation

If you are planning a comprehensive repair or upgrade of the steering system area in your Mercedes and need other elements from the same group, such as additional hoses, return lines, or connecting elements, check the available parts in the Mercedes Power Steering Hoses category.

During service work, it is also worth verifying the condition of other vehicle components, especially before the low-temperature season – you can find practical tips and checklists in the article Winter essentials: which used car parts are worth checking and replacing before the frost?.
