How to Replace Summer Windshield Washer Fluid in Winter?
2 Answers
Here are the precautions for replacing summer and winter windshield washer fluids: 1. If it's the same brand of washer fluid: There's no need to spray out the summer washer fluid; you can directly add the winter washer fluid, as they can be mixed. 2. If it's not the same brand: First, completely drain the summer washer fluid before pouring in the winter washer fluid. Different brands of washer fluids contain different ingredients, and some may react, forming sediment that can clog the spray nozzles, eventually preventing any fluid from being sprayed. To remove the summer washer fluid, simply hold down the washer fluid spray button. If your vehicle has a headlight cleaning function, using it will quickly drain the washer fluid. 3. Adding winter washer fluid: Open the engine hood, locate the filler cap with the washer fluid symbol (usually a blue cap), open it, and pour in the winter washer fluid. 4. Do not continuously spray washer fluid with the engine off: The washer pump consumes a significant amount of power. Continuously using the washer with the engine off can quickly drain the battery. Therefore, do not turn off the engine when replacing the washer fluid.
Having driven for many years, I know that replacing windshield washer fluid is a task that needs attention by late autumn. The summer-use washer fluid doesn't contain antifreeze, and once winter temperatures drop below freezing, it will freeze. A blocked nozzle pipe is a minor issue if it just prevents water from spraying and obscuring your vision, but a frozen motor can lead to costly repairs. Quickly pop the hood and locate the plastic reservoir at the front marked for the windshield washer. Spray out the old fluid until it's used up or use a thin tube to siphon it out, ensuring not a drop remains. Pour in winter-specific fluid—opt for a reputable brand from the supermarket, and check the label to ensure its antifreeze rating matches your region's coldest temperatures (in Northeast China, -30°C is common). Act fast before temperatures hit freezing to avoid driving with poor visibility on late-night trips. Regularly check if the nozzles are clogged, and after refilling, test-spray a few times to ensure smooth operation. Winter driving safety relies on these small but crucial details.
