What are the hazards of frozen windshield washer fluid to the car?

[DeDominic]

The hazards of frozen windshield washer fluid to the car include volume expansion leading to tank rupture, damage to the electrical system, and compromised driving safety. Below are methods to thaw frozen windshield washer fluid: 1. Sun exposure. If you find that the windshield washer fluid is frozen and you are not in a hurry to use the car, you can open the engine hood and position the engine compartment toward the sun to utilize solar heat to dissolve the fluid. Of course, the drawback of this method is quite obvious—it is heavily influenced by weather conditions. If there is no sun or the sunlight is not strong enough, it will affect the efficiency of thawing the windshield washer fluid. 2. Pouring hot water. Boil a pot of hot water and slowly pour it over the opening of the windshield washer fluid reservoir. This method is relatively troublesome, and if the freezing is severe, one pot of hot water may not be sufficient to resolve the issue. 3. Utilizing engine heat to thaw. Use the high temperature generated by the running engine to dissolve the windshield washer fluid. It is important to note that when the windshield washer fluid is not completely thawed, do not use the spray function, as it may cause damage to the spray motor.
