Flexi Says: The three main ingredients of coolant are water, antifreeze, and dye. It is water that acts as a coolant. The antifreeze such as ethylene glycol containing phosphates, silicates as an antirust agent, is added to water to reduce its freezing point so that the coolant does not freeze at its normal freezing point. The coolant comes in different colors due to the addition of dyes. The color of the coolant represents the type of chemical used to prevent corrosion. For example, the green color coolant consists of silicates as inhibitor technology.
