Purpose and function in the washer system

The presented reservoir belongs to the Washer fluid reservoirs, pumps, and nozzles category and is responsible for storing the operating fluid and supplying it steadily to the washer pump. Its precisely selected geometry and mounting points allow for secure seating in the SLK R170 body without interfering with other components.

Its original Mercedes origin ensures that factory dimensional tolerances are maintained, which facilitates installation and minimizes the risk of leaks at the connection ports and around the washer system mounting points.

Construction and fitment for the Mercedes SLK R170

The reservoir has been designed specifically for the architecture of the SLK R170 body, taking into account the routing of hoses, pump location, and service access. As a result, it:

• fits the factory mounting points in the body,
• ensures proper routing of the washer fluid hoses,
• maintains the appropriate operating capacity for daily use,
• allows for the correct seating of the washer system components.

Such fitment reduces the need for modifications and allows for maintaining consistency with the factory design of the washer system in the Mercedes SLK R170.

Condition, origin, and benefits of using a used part

This item comes from the used parts segment, which allows for reducing repair costs while maintaining the manufacturer's original design. In the case of washer fluid reservoirs, maintaining the integrity of the body and stable mountings is crucial – using an original component from disassembly helps maintain proper geometry and compatibility with factory equipment.

For many Mercedes owners, choosing a used reservoir is a reasonable compromise between price and quality, especially when they want to maintain original design solutions instead of aftermarket replacements with uncertain fitment.

Technical support, selection, and additional information

When selecting a washer fluid reservoir for a specific SLK R170 unit, it is worth paying attention to compatibility with the body version and the washer system configuration. Vehicle identification data and manufacturer markings can be helpful, allowing for precise verification of compatibility with a given model.
