Does adding windshield washer fluid to coolant have any impact?

[IvanMarie]

Adding windshield washer fluid to the coolant will lower both the freezing point and boiling point of the coolant. If not cleaned and replaced for a long time, it can affect heat dissipation. Moreover, windshield washer fluid has certain corrosive properties, and in severe cases, it can corrode the cooling system, leading to engine damage, which can have serious consequences. The role of coolant: Coolant is a type of cooling liquid containing special additives, mainly used in liquid-cooled engine cooling systems. It has excellent properties such as preventing freezing in winter, preventing boiling in summer, and offering year-round protection against scale and corrosion. Can different coolants be mixed? It is necessary to use the same brand of coolant. Different brands of coolant may have varying production formulas, and mixing them could lead to chemical reactions between the additives, rendering them ineffective. How to choose coolant: The basic indicators of coolant are the freezing point and boiling point. On the market, coolants come in various specifications such as -15°C, -25°C, -30°C, and -40°C. Generally, it is advisable to choose a coolant with a freezing point at least 10°C lower than the lowest temperature in your region.
