What do the coolant colors in a car indicate?

The different coolant colors in a car can indicate different types of solutions used in its manufacture. For example, green is usually associated with ethylene glycol based solutions, while red can indicate an OAT (organic acid) based solution. It is important to highlight that, regardless of the color, it is essential to maintain a good quality and concentration of the coolant to prevent problems in the car engine's cooling system.
