Is it a serious problem if the windshield washer fluid overflows?

It is not a serious problem if the windshield washer fluid overflows, for the following specific reasons: 1. The engine compartment is designed with open spaces at the top and bottom, allowing the fluid to naturally flow to the ground, so there is no need to worry. 2. Key parts of the engine compartment, such as the engine box and wiring, are sealed, so there is no cause for concern. The functions of windshield washer fluid are as follows: 1. Cleaning performance: The fluid is composed of various surfactants and additives. Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby aiding in cleaning and removing dirt. 2. Antifreeze performance: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, 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.
