Windshield washer fluid is added into the independent washer fluid reservoir located in the engine compartment. Below are some details about windshield washer fluid:1. When adding washer fluid, first pull the engine compartment release handle inside the cabin, open the engine hood, then locate and fill up the washer fluid filler port.2. The washer fluid tank is usually positioned near the edge, with a cap marked with a windshield washer symbol. Note that the filling capacity varies by vehicle model. Typically, the washer fluid capacity is 2 liters. Fill up to 1cm below the bottle neck when adding.3. Commonly known as automotive windshield cleaning fluid. It is a consumable item in vehicle maintenance. High-quality windshield washer fluid mainly consists of water, alcohol, ethylene glycol, corrosion inhibitors and various surfactants. In southern regions, washer fluid with insect remover additives is generally sufficient. In northern winters, antifreeze washer fluid must be used.

The place to add windshield washer fluid is usually under the hood. After opening the hood, look for a small reservoir cap with a windshield wiper icon, which is typically blue or green in color—this is called the washer fluid reservoir. Having driven for over a decade, I’ve found this to be the standard location in every car, near the windshield at the front of the engine bay. Use a funnel or pour the cleaning fluid directly, but avoid using tap water—algae can grow in summer, and it may freeze and clog the nozzles in winter, causing unnecessary trouble. Remember to check the fluid level monthly, especially during rainy or snowy seasons when usage is higher. After refilling, test the wiper spray. If the stream is weak or misaligned, the nozzles might be dirty and need cleaning. The vehicle manual includes detailed diagrams, and while the exact position may vary slightly in newer models, the setup is generally the same. Developing this good habit can prevent panic when visibility suddenly drops on the road.

In my years of car repair experience, the windshield washer fluid filler is located inside the engine compartment. The cap has a clear wiper symbol, mainly in turquoise, and is generally positioned near the firewall or the bottom of the windshield. When refilling, use dedicated windshield cleaning fluid and avoid other liquids to prevent corrosion of the reservoir or damage to the pump. Safety first—wait for the engine to cool down before operating to avoid burning your hands. I recommend checking the fluid level weekly and filling it halfway to the full mark to prevent overflow. Additionally, check if the spray nozzles are clear; weak water flow is often caused by debris blockage and needs to be blown clear. There are slight variations between different car models—SUVs tend to have higher positions while sedans are lower—but always refer to the manual for accuracy. Regular maintenance of this simple step can extend the system's lifespan, avoiding unnecessary expenses from faulty nozzles.

When I first started learning to drive, I had no idea where to add windshield washer fluid. After opening the hood, the instructor pointed out a small blue cap located near the engine at the front left side. Just pour in the cleaning solution bought from the supermarket, but don't fill it too full to avoid overflow, then test the wipers to check the effect. If you can't find it, checking the user manual is the fastest way - the pictures inside are clearer. Beginners often pour into the wrong opening, just remember the tank cap has an icon for safety. Later I got used to it, adding a little each time I wash the car to ensure clear visibility while driving.
