Do Different Colors of Coolant Indicate Different Functions?

[MarianaLee]

Coolants of different colors have the same function. Coolant is originally produced as a colorless and transparent liquid. Dyes are added to distinguish it from other liquids, without any special function, and it has no impact on the coolant's performance and quality. The primary purpose of adding color is to help car owners easily check the water level line in the car's radiator, allowing them to replenish it in time if it's low and prevent overflow during operation to ensure safe driving. There is almost no difference in the function of coolants; their main purpose is to cool the vehicle. The operation of a car requires the engine to continuously provide kinetic energy, which generates a significant amount of heat in the process. If the heat is too high, it can cause serious damage to the engine, so coolant is used to quickly cool the engine.
