Every driver sooner or later faces the problem of windshield washer fluid freezing in the power system. This problem may be associated both with poor-quality washer fluid and with the physical processes that it undergoes. However, there is an inexpensive and effective solution for both scenarios.

If the washer fluid suddenly froze in the pipes or nozzles, then most likely it does not meet the declared characteristics. In this case, simply switch to another brand, and if necessary, file a claim with the manufacturer of the low-quality product (if you can find one).

Before blaming the manufacturer of the washer fluid, it is recommended to conduct a simple experiment to check whether the characteristics of the antifreeze fluid stated on the label do not correspond to the real ones. Take a bottle with some liquid and place it in the trunk. If the washer fluid is truly of dubious quality, then the experiment will not take much time to reveal the deception: it will quickly turn into a gel-like substance or even freeze completely at the first frost.

However, sometimes the liquid placed in the trunk may not freeze even in severe frost, and then nothing will flow from the windshield washer nozzles. If you are convinced that the pump is working properly and there are no leaks, then the problem may lie in physical processes.

To keep the windshield clean for a long time, automakers have come up with a simple but original function. When the windshield wipers first sweep, a washer fluid is sprayed onto the glass, which serves as both a cleaning agent and a lubricant.

To prevent fluid from flowing back into the reservoir and ensure its immediate supply upon driver demand, a check valve is built into the supply system. You can install several valves – one for each injector or one valve for all injectors.

However, the principle of their operation remains unchanged – when the pump is turned on, the valve opens, allowing liquid to enter the glass. After turning off the pump, the valve closes, preventing washer fluid from flowing back into the reservoir. Therefore, the next time you press the steering column lever, a stream of antifreeze liquid bursts out of the injectors.

However, the composition of the liquid in the supply tubes may change over time – when heated, isopropyl alcoholwhich forms its basis, evaporates. Therefore, if you have not used the sink for a long time, the liquid remaining in the tubes may lose some of its properties and freeze.

WHAT CAN BE DONE?

To prevent washer fluid from freezing in the supply pipes, it is recommended to remove the check valve in the winter. When there is an abundance of slush and moisture, turning on the lever in most cases causes the windshield wipers to operate on a wet surface without causing harm. Although there may be a slight delay in the supply of antifreeze, the risk of ice forming in the supply pipes and nozzles will be minimized.

However, the best way to ensure clear vision on the road is to use a high-quality washer fluid from a reputable manufacturer.
