Do I Need to Turn Off the Engine When Adding Windshield Washer Fluid?

[AlexRose]

Adding windshield washer fluid does not require the vehicle to be turned off, as it has no impact on the engine. Functions of windshield washer fluid: 1. Cleaning performance: Windshield washer fluid typically has wetting, penetrating, and solubilizing functions, thereby serving to clean and remove 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. Below are the main functions of vehicle antifreeze: 1. Anticorrosion: It prevents the engine from freezing in winter. Antifreeze, also known as coolant, is a special additive liquid with excellent anticorrosion properties, preventing scale buildup inside the engine and being resistant to evaporation. If the antifreeze level is low during vehicle use, it should be replenished promptly. If the antifreeze is severely lacking, it is necessary to check for potential issues. 2. Service life: Vehicle antifreeze can be used for about two years. There is a common misconception that antifreeze is only used in winter, which is incorrect. Antifreeze is required year-round to ensure the normal operation of the engine and prevent overheating.
