Should Windshield Washer Fluid Be Drained in Winter?

[KatherineFitz]

Whether the windshield washer fluid needs to be drained in winter depends on whether the fluid in the reservoir is of the antifreeze type. If summer windshield washer fluid was previously added, meaning its freezing point does not meet the required standards, it must be drained and replaced with antifreeze windshield washer fluid. Otherwise, there is a risk of the fluid freezing, which could damage the reservoir or the washer pump. Choosing Windshield Washer Fluid: When selecting windshield washer fluid, antifreeze performance should be the primary criterion. Choose a fluid with a freezing point at least 10 degrees below the local minimum temperature to prevent issues like frozen fluid or pump failure. Function of Windshield Washer Fluid: Leaving the reservoir empty in winter without adding fluid is not advisable, as windshield washer fluid is a consumable necessity for driving, playing a crucial role. It offers functions such as cleaning, antifreeze protection, antistatic properties, and corrosion prevention. It also helps quickly melt snow and ice, prevents fogging and glare, significantly contributing to driving safety. When the windshield becomes blurry, spraying some windshield washer fluid can help clean it, making the view clearer.
