The windshield washer fluid in a Golf is added on the left side of the engine near the headlight, where there is a blue cap with a water spray symbol. Simply open the cap and pour in the washer fluid. Below are the functions of windshield washer fluid: 1. Cleaning Performance: Windshield cleaner is formulated with various surfactants and additives. Surfactants typically have wetting, penetrating, and solubilizing functions, thereby providing cleaning and stain removal effects. 2. Anti-Freeze Performance: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, 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 cleaner, substances adsorbed on the glass surface can eliminate static charges, providing anti-static properties. 5. Lubrication Performance: The ethylene glycol in the windshield cleaner has a high viscosity, providing lubrication to reduce friction between the wiper blades and the glass, preventing scratches. 6. Anti-Corrosion Performance: Windshield cleaner contains various corrosion inhibitors, ensuring no corrosion to any metals, and is absolutely safe for car paint and rubber.

After driving a Golf for so many years, I can find the windshield washer fluid reservoir with my eyes closed. After opening the hood, there's a plastic tank located on the left front side of the engine compartment with a bright blue cap featuring a windshield washer icon. The exact position might vary slightly between the 6th and 7th generations, but it's always nearby. Before refilling, I always check the fluid level to ensure it's above the MIN line but not exceeding the MAX line to avoid overflow. I recommend using professional windshield cleaning fluid instead of tap water for convenience, as impurities can clog the nozzles and be hard to clean. In autumn and winter, I switch to an antifreeze windshield washer fluid to prevent freezing in low temperatures. While driving, pressing the washer button when visibility is blurry helps clean the windshield, making driving much safer.

From an automotive enthusiast's perspective, the windshield washer fluid reservoir in a Golf has a very fixed location. After lifting the hood, you'll find a blue-capped reservoir on the driver's side front, marked with a windshield wiper spray symbol. I always prefer using high-quality washer fluid with wiper blade lubricant, and pour it slowly to avoid spilling onto other components. The design remains largely consistent across different Golf model years, though the 8th generation might position it slightly more toward the center. Quarterly refills are sufficient, and it's a good opportunity to check for clogged nozzles. I recommend choosing a summer formula with insect remover, or antifreeze fluid for cold regions. Maintaining proper fluid levels is crucial.

Pro Tip: The windshield washer fluid reservoir is located under the hood on the left side, marked by a blue-capped plastic container with a clear icon. Simply open the cap and pour in the fluid, being careful not to mistakenly add it to the coolant reservoir. Always use commercially available dedicated windshield washer fluid, with winter antifreeze formula being essential. Remember this simple location.
