Mercedes Washer Fluid Reservoir Cap - Genuine Mercedes 1778690500

Product Information

A washer fluid reservoir is a plastic tank that holds the windshield washer fluid in a vehicle. This fluid is sprayed onto the windshield to help clear dirt, debris, and other obstructions, ensuring good visibility. The reservoir is typically located under the hood and connected to the washer pump and nozzles via tubing.

• Fluid Leaks: Cracks or punctures in the reservoir may cause washer fluid to leak, resulting in low or empty fluid levels despite refilling
• Frequent Refill Needed: If the reservoir empties faster than usual, it’s a sign that there may be a leak somewhere in the reservoir or its connected lines.

About Genuine Mercedes

The original parts used by Mercedes Benz to build your car are available as replacement parts under the “Genuine Mercedes Benz” brand. Manufactured under the direction of Mercedes Benz, expect excellent quality and a premium price since these parts are exclusively available through the Mercedes Benz Dealership network.

You may not realize this, but the parts that make up your Mercedes-Benz are not necessarily manufactured by Mercedes-Benz. No cause for concern, as Mercedes-Benz designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Mercedes-Benz for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Mercedes-Benz parts box and find an OEM branded part inside, simply with the addition of a Mercedes-Benz logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
