How to Drain Windshield Washer Fluid?
2 Answers
Windshield washer fluid can be drained using the following two methods: Using the siphon principle to extract the fluid: Open the engine hood and locate the black plastic tube on the cover—this is the windshield washer fluid tube. Remove the nozzle, point it outward from the vehicle, and continue spraying. (Note: While draining the fluid, clean the windshield simultaneously to avoid waste.) Siphon method: Siphoning utilizes the force generated by the height difference of liquid surfaces. After filling an inverted U-shaped tube structure with liquid, place the higher open end into a container filled with liquid. The liquid in the container will continuously flow out through the siphon tube from the lower opening.
As a car owner who frequently does DIY repairs, let me share how to use windshield washer fluid. It's actually quite simple—just operate the wiper control stalk next to the steering wheel while seated in the driver's seat. Typically, pulling the stalk outward or giving it a gentle inward flick will activate the nozzles to spray fluid onto the windshield. If nothing comes out, the most common issue is an empty reservoir. In this case, park the car, pop the hood, locate the blue-capped washer fluid reservoir (usually in a corner of the engine bay), open the cap, and pour new fluid up to the fill line. For safety, choose antifreeze washer fluid in winter to prevent freezing, while summer formulations with stronger cleaning power work fine. Another common problem is clogged nozzles—I gently clear them with a fine needle. Regular checks of fluid levels and cleaning performance ensure long-term reliability of the wiper system.
