Washer Fluid Tank – FEBI BILSTEIN 109525 OE-Spec

Streaky, sluggish, or completely dry washer jets almost always trace back to a failing washer fluid tank. The FEBI BILSTEIN 109525 washer fluid tank replaces the worn factory component with an OE-spec part designed as a reservoir that stores and supplies washer fluid to your windshield washer pump and spray jets, restoring dependable spray performance in one straightforward repair.

FEBI BILSTEIN is an established manufacturer of OE and OE-matching automotive components, and its washer-system parts are engineered to the tolerances specified by original vehicle manufacturers rather than to a generic universal fit. 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

The FEBI BILSTEIN 109525 is intended as a direct replacement for the original washer fluid tank on applicable vehicles, restoring the washer system to factory-correct operation. Typical triggers for replacement include a washer reservoir that no longer holds fluid overnight, a persistent washer fluid warning light, fluid pooling near the front bumper or fender liner, or brittle plastic that has become sun-damaged over years of engine-bay heat cycles. Whether the vehicle is used for a daily commute, highway travel, or fleet service, keeping the washer system in working order is a straightforward, low-cost way to maintain safe forward visibility. Because the part is manufactured to OE dimensions, it’s also a practical choice for pre-emptive replacement during a broader washer-system service — for example, when a technician is already replacing a washer pump or wiper blades and wants to rule out a related failure point at the same time.
