What kind of water should be added to the car windshield washer reservoir?
2 Answers
Special windshield washer fluid should be added to the car windshield washer reservoir. The functions of automotive windshield washer fluid include: 1. Cleaning performance: The surfactants in windshield washer fluid typically have wetting, penetrating, and solubilizing functions, which help clean and remove dirt; 2. Antifreeze performance: The presence of alcohol and ethylene glycol lowers the freezing point of the liquid, providing antifreeze protection; 3. Anti-fog performance: A monomolecular protective layer forms on the glass surface, ensuring clear and transparent visibility on the windshield. The windshield wiper is a blade structure installed in front of the windshield, composed of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly.
I've been driving for over a decade, and I advise against adding random substances to the windshield washer reservoir. Dedicated windshield washer fluid is the most hassle-free option, available at supermarkets for around ten yuan per bottle. In summer, the standard version suffices; occasionally adding tap water in emergencies is acceptable, but prolonged use can lead to nozzle clogging due to mineral deposits, weakening the spray. In winter, switch to an antifreeze type—freezing temperatures can cause the reservoir or pipes to crack, leading to costly repairs. To refill, open the hood, locate the round container or reservoir labeled for windshield washing, unscrew the cap, and pour carefully to avoid spills. I make it a habit to check the fluid level every few thousand kilometers and top it up promptly to prevent drying out. This ensures clear visibility and prevents wiper blade damage—safety always comes first.
