What is the freezing point of non-freeze-resistant windshield washer fluid?
3 Answers
Generally, non-freeze-resistant windshield washer fluid has a freezing point around 0 degrees Celsius. Windshield Washer Fluid: If the local temperature is low and the washer fluid is not freeze-resistant, it may freeze, potentially leading to issues such as the fluid itself freezing, severe cases where the washer fluid reservoir cracks, or damage to the windshield washer pump. Requirements for Choosing Windshield Washer Fluid: When selecting windshield washer fluid, freeze resistance should be the primary criterion. Choose a fluid with a freezing point at least 10 degrees Celsius below the local minimum temperature. Most brands categorize their washer fluids by temperature range, allowing selection based on seasonal changes. Typically, 0-degree Celsius fluid can be used in summer, while in winter, fluids rated for at least -20 degrees Celsius or -35 degrees Celsius should be used. For extreme weather conditions, specialized anti-freeze washer fluids are available, which generally remain unfrozen even at -40 degrees Celsius.
As a regular parent who drives, I am particularly concerned about my child's safety. Ordinary windshield washer fluid tends to freeze at around zero degrees Celsius. In winter, if the windshield gets dirty but you can't spray water, visibility becomes blurred, increasing the risk of accidents. Last year, I once didn't use the antifreeze type, and the entire can froze into ice at low temperatures, completely clogging the nozzles. My car almost skidded on the road, but fortunately, I handled it in time. Since then, I always use antifreeze windshield washer fluid in cold weather—it can withstand lower temperatures, such as around minus ten degrees Celsius. Never cut corners by using the ordinary type in low temperatures. It's also important to regularly check the condition of the reservoir to avoid freezing and damaging the lines.
I've been transporting goods on highways for years, and experience tells me that regular washer fluid typically freezes between zero degrees and its freezing point. Once, I didn't switch it out before a night drive, and when temperatures dropped below zero, the cleaning system completely failed. I had to stop for half a day waiting for it to thaw—what a hassle. Now, before winter hits, I switch to the antifreeze type early, checking the bottle label for its cold resistance range. Using regular water saves little money, and if it freezes, it could damage the nozzles or hoses, leading to even higher repair costs later. Make it a habit to check the weather forecast—when temperatures drop, avoid regular water altogether.
