Can Car Windshield Washer Fluid Freeze?

[NolanAnn]

Car windshield washer fluid can freeze. Once frozen, it can easily cause the reservoir and hoses to crack. Continuously pulling the washer lever to spray the fluid may also lead to motor burnout. Solutions for frozen washer fluid include: 1. Park the car in the sun to use solar radiation to raise the temperature and thaw the fluid; 2. Add some warm water to the reservoir to melt the frozen fluid—avoid using boiling water as it can damage the hoses; 3. Start the car engine, as the heat from the engine can help dissolve the frozen fluid; 4. After the regular washer fluid thaws, replace it with an antifreeze-type washer fluid.
