Function and Application of the Under-Windshield Drain Hose

The under-windshield drain hose in the Mercedes R171 is responsible for the controlled drainage of water from the space under the plastic cowl panel, in the battery area. A properly functioning drain:

• reduces the risk of water and mud accumulation around the battery,
• limits the possibility of corrosion of metal components in the cowl compartment,
• protects electrical harnesses and connectors from prolonged moisture,
• supports stable operation of the vehicle's electrical systems.

Thanks to its factory fit for the R171 body, the hose maintains the correct routing and diameter, which translates to stable water flow even during heavy rainfall.

Construction and Fit for Mercedes R171

This component is designed as part of the under-windshield drainage system for Mercedes vehicles, taking into account the specific shape of the space under the windshield and in the battery area. The appropriately shaped ends and geometry of the hose:

• facilitate installation in factory mounting points,
• ensure a sealed connection with the cowl panel and the body drain,
• minimize the risk of kinks and blockages during operation.

Its original origin from the Washer Fluid Tanks, Pumps, and Nozzles group means the hose is part of the liquid management system in the front of the vehicle, working with other components responsible for draining water and operating fluids.

Condition, Origin, and Benefits of Choosing a Used Part

The offered hose is a used part, sourced from disassembly, which allows for economical repair while maintaining factory fit for the Mercedes R171. Choosing an original second-hand part means:

• maintaining compatibility with the body structure and drainage system,
• reducing the risk of installation problems typical of aftermarket parts,
• a sensible compromise between cost and quality of execution.

This solution allows for restoring proper water drainage from the cowl without affecting other system components.

Selection by Numbers and Integration with Other Systems

The under-windshield drain hose works with components responsible for draining water and operating fluids in the front of the vehicle. When selecting a part, it is advisable to use manufacturer markings and interchangeable numbers to ensure full compatibility with the specific body version and equipment.
