Purpose and function in the washer system

The presented pump operates within the washer fluid reservoir, pump, and nozzle system, responsible for pumping fluid from the reservoir to the hoses and nozzles. A properly functioning motor guarantees an even stream, which reduces fluid consumption and improves windshield cleaning efficiency, especially at higher driving speeds.

The original Mercedes solution allows for maintaining the correct operating parameters of the vehicle's electrical system, minimizing the risk of overloads, controller errors, or unstable washer operation.

Construction and installation fitment

The pump is designed as a component that works directly with the fluid reservoir and factory washer hoses in C117 family models. The construction of the housing and connection ports allows for installation in the original socket without the need for modifications, which shortens service time and reduces the risk of leaks.

The factory electrical connector ensures a proper connection with the vehicle's wiring harness, and the appropriately selected motor operating parameters allow for maintaining the correct flow efficiency and operating pressure throughout the system.

Condition, verification, and service application

The item comes from dismantling and is offered as a used original Mercedes part, which is a cost-effective alternative to new components while maintaining factory specifications. This type of pump is suitable both for standard replacement of a worn-out motor and for repairs after a collision or interference with the front part of the bodywork.

Thanks to the preservation of the original geometry and operating parameters, the part is particularly recommended in situations where you care about compatibility with factory controls and avoiding problems typical of replacements with uncertain parameters.

Benefits of using an original washer pump

• Maintaining proper washer system efficiency and even spray on the windshield.
• Factory fitment to the vehicle's electrical and hydraulic installation.
• Reduction of the risk of leaks and lack of tightness thanks to the correct geometry of the connections.
• A reasonable compromise between repair cost and maintaining manufacturer specifications.
