The symbol for the windshield washer fluid refill location is a symbol resembling a windshield spray, marked with a blue plastic cap featuring a spray pattern. The washer fluid cap usually has a wiper symbol printed on it. Additional information is as follows: Functions of windshield washer fluid: 1. Cleaning performance: Windshield washer 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. Anti-freeze performance: It can significantly lower the freezing point of the liquid, thus providing anti-freeze properties 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. 4. Anti-static performance: After cleaning with windshield washer fluid, substances adsorbed on the glass surface can eliminate the charge on the glass surface, providing anti-static properties. 5. Lubrication performance: It has a higher viscosity, which provides lubrication, reducing friction between the wiper and the glass to prevent scratches.

I'm totally qualified to speak on this. The windshield washer fluid symbol is a fan-shaped spray pattern that resembles the shape of a windshield, with a few water ripples in the middle. All car models place it at the top of the left-hand stalk on the steering wheel, and some vehicles mark it in blue or green. Don’t force it in cold weather—if it’s frozen, you could burn out the motor. I’ve seen plenty of new drivers confuse it with the light stalk and end up spraying pedestrians on a sunny day. Remember to switch to antifreeze type in subzero temps—once I forgot and cracked the plastic reservoir. Honestly, the owner’s manual is the most accurate—German cars use an icon like a water jet piercing glass, while Japanese models prefer dotted lines to represent water flow.

From a mechanic's perspective, the windshield washer fluid symbol is quite intuitive. That blue fan-shaped button with water droplets is the one - pressing it automatically activates the wipers for three sweeps. The key is checking if the spray angle is correct; clogged nozzles can turn it into a water curtain cave. We've found green algae when unclogging nozzles for owners who used tap water (which causes mineral buildup). Recommend quarterly cleaning of wiper arm joints where sediment buildup most affects spray performance.
