Should Water Be Added When Refilling Windshield Washer Fluid?

[Cook]

Whether water should be added when refilling windshield washer fluid depends on the situation. Solid windshield washer fluid needs to be dissolved with water, while for liquid windshield washer fluid, the concentration should be considered. High-concentrate windshield washer fluid has highly corrosive properties and must be diluted with water according to the specified ratio before use. Non-concentrated liquid windshield washer fluid can be used directly. The method for adding solid windshield washer fluid is as follows: First, open the hood (the hood release is usually located near the driver's left foot). After opening, locate the windshield washer fluid reservoir, which is marked with a blue plastic cap. Place the solid windshield washer fluid inside and add water. It's important to note that the typical capacity of a car's windshield washer fluid reservoir is about 3 liters, so avoid overfilling.
