Washer Fluid Tank – FEBI BILSTEIN 109523 OE-Spec

When your washer fluid stops reaching the nozzles, visibility on the highway suffers fast. This FEBI BILSTEIN 109523 washer fluid tank is built to OE specifications as a reservoir that stores and supplies washer fluid to your windshield washer pump and spray jets, giving you a bolt-in fix instead of a guessing game of aftermarket approximations.

Every washer-system component in our catalog is checked against the manufacturer’s published part number and EAN prior to listing, so the specifications you see reflect the original factory component rather than a generic guess.

Use Cases & Applications

This part is built for drivers who want their windshield washer system functioning exactly as the manufacturer designed it — no workarounds, no compromises. It’s a common fix for vehicles showing symptoms such as reduced or uneven washer spray, fluid leaking under the hood or around the reservoir, a washer fluid warning light that won’t clear even after refilling, or visible cracking and discoloration in the plastic housing. Independent repair shops, dealership service departments, and confident DIY owners all rely on OE-spec parts like this one because they eliminate the fitment guesswork that comes with universal, one-size-fits-most alternatives. It also works well as part of a broader washer-system refresh — many shops replace this component alongside a washer pump, wiper blades, or fluid lines during a single service visit to minimize repeat labor down the road.
