Differences Between Coolants of Different Colors

[OEvangeline]

Coolants of different colors indicate different types. In fact, the color is due to the dye added to the liquid, which is only used to distinguish it from other liquids and has no other special functional purpose. It also helps users differentiate when selecting a coolant to prevent mixing different types, which could damage the engine. Functions of Coolant: Coolant is a type of cooling liquid containing special additives, primarily used in liquid-cooled engine cooling systems. It has excellent properties such as preventing freezing in winter, boiling in summer, and protecting against scale and corrosion throughout the year. Can Different Coolants Be Mixed? The same brand of coolant must be used. Different brands of coolants may have varying production formulas. If mixed, chemical reactions between multiple additives may occur, rendering the additives ineffective. How to Choose a Coolant: The basic indicators of coolant are the freezing point and boiling point. In the market, coolants come in several specifications with freezing points such as -15°C, -25°C, -30°C, and -40°C. Generally, it is advisable to choose one that is at least 10°C lower than the lowest temperature in your region.
