How to Drain the Windshield Washer Fluid from the Car?
2 Answers
To drain the windshield washer fluid from the car, follow these steps: 1. Start the car and press the windshield washer button, continuously spraying the fluid until it runs dry. 2. Siphon Method: (1) Open the hood and locate the windshield washer fluid reservoir cap. Insert a 2-meter-long soft hose into the reservoir, pushing it as far in as possible. (2) Connect a syringe to the other end of the hose and draw out the fluid from the reservoir. When the fluid level drops to about the height of the headlights, remove the syringe, place the hose on the ground, and let the remaining fluid drain out.
When I first learned about cars, I was also curious about how to drain the windshield washer fluid. It's actually quite simple: open the hood, locate the plastic reservoir (usually on the left or right side of the front with a spray icon marking), and remove the cap. If there's a drain plug at the bottom, unscrew it to let the fluid flow out; otherwise, use a siphon or manual pump. Remember to turn off the engine for safety. Why drain it? Old fluid may have degraded over time, or you might need to switch to antifreeze-type fluid before winter to prevent freezing. After draining, don’t pour the old fluid on the ground—its chemicals can pollute the environment. Collect it and dispose of it properly at a recycling station. Check the reservoir’s cleanliness; rinse it if needed before refilling to avoid nozzle clogs from residue. This method has worked well for me over the years.
