What are the effects of frozen windshield washer fluid on a car?

Frozen windshield washer fluid can have the following two specific effects on a car: 1. It can easily cause the water tank and hoses to burst. 2. It can easily lead to the burning out of the washer motor. The functions of windshield washer fluid include the following three aspects: 1. Cleaning performance: Windshield cleaner is formulated with various surfactants and additives. Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby achieving the effect of cleaning and removing dirt. 2. Antifreeze performance: The presence of alcohol and ethylene glycol can significantly lower the freezing point of the liquid, thus providing antifreeze effects and quickly dissolving frost. 3. Anti-fog performance: A single-molecule protective layer forms on the glass surface. This protective film prevents the formation of fog droplets, ensuring the windshield remains clear and transparent with a clear field of vision.
Frozen windshield washer fluid is way too common - I learned this the hard way last winter. The most immediate impact is clogged spray nozzles, causing wipers to screech horribly when dragging dry across the glass. Worse, expanding frozen fluid can crack the reservoir tank, with repairs costing hundreds. Forcing the washer pump to operate risks burning out the motor - replacement runs 300-400 RMB. The real danger comes from compromised visibility when the windshield gets dirty, especially hazardous during snowfall. Recommended solutions include thawing with lukewarm water or parking underground to melt naturally. Pro tip: Switch to winter-grade fluid - these lessons cost me real money.
For those who frequently drive long distances, frozen windshield washer fluid is no trivial matter. A dirty windshield that can't be cleaned leads to blurred vision and easily causes accidents. I've seen cases where the reservoir froze and cracked, with antifreeze mixed with washer fluid leaking all over the engine compartment. Another lesser-known issue: the washer pump motor's continuous dry running can burn out its coils - replacing an OEM motor at repair shops costs over 500 yuan. For emergency thawing, medical alcohol can be added, but keep the ratio below 30%. Long-term solution: before winter, always switch to -25°C rated washer fluid, and don't fill the reservoir completely - leave room for expansion. I now keep a bottle of concentrated antifreeze in the trunk as backup.
