Purpose and function of the washer hose

The presented flexible hose is responsible for transporting fluid from the washer system to the headlight nozzles in the front of the body. Thanks to its properly selected diameter and flexibility, it ensures:

• stable fluid pressure during system operation,
• proper fit to factory mounts and routing in the front compartment,
• reduced risk of kinks and leaks at critical points of the installation.

Such a solution allows you to keep the headlights clean, which is important both for the quality of road illumination and for compliance with technical inspection requirements.

Application in the Mercedes W164

The Mercedes headlight washer hose has been designed to maintain the factory installation routing in W164 series models. The appropriate shaping of the hose facilitates its routing in the front zone of the vehicle, minimizing stress and contact with other equipment components.

As a result, the installation is carried out in a manner similar to the factory standard, and the headlight washer system can operate under stable conditions without the need for modifications or additional clamps.

Component characteristics and benefits of installation

As an element from the Other wiper parts group, the hose works with other system components, such as the pump, fluid reservoir, or nozzles. Its use allows you to:

• restore full functionality of the headlight washers after damage or wear of the old hose,
• maintain the factory installation configuration without using universal replacements,
• preserve the consistency of the system responsible for the cleanliness of windows and headlights.

This solution is particularly beneficial for users who prioritize original Mercedes components and want to avoid problems with fitment or installation leaks.

Condition, origin, and selection of parts

The offered hose comes from dismantling and is a used item, which allows for combining reasonable cost with maintaining the geometry and routing specific to Mercedes. In practice, this means the possibility of an economical repair of the washer system while maintaining the original design.

When selecting a hose for a specific vehicle, it is worth verifying compatibility with the vehicle's equipment and headlight configuration. Manufacturer markings and part numbers, which can be found in the technical specifications section, may be helpful.
