Difference Between Antifreeze and Coolant?

[DelAaliyah]

There is no difference between antifreeze and coolant. Coolant is the abbreviation for antifreeze coolant, meaning it is a coolant with antifreeze properties. Antifreeze is not only used in winter but should be used year-round. As part of regular vehicle maintenance, the engine antifreeze should be replaced every year. Antifreeze consists of three components: water, antifreeze agents, and additives. Based on the antifreeze agent used, it can be categorized into alcohol-based, glycerol-based, and ethylene glycol-based types. Long-term failure to replace antifreeze can lead to changes in its quality, reducing its anti-corrosion properties, which may damage the radiator and pipes. It can also affect the boiling and freezing points, impairing the antifreeze or cooling effects, causing harm to the engine. During each vehicle maintenance session, a refractometer can be used to test the freezing point of the antifreeze. If the freezing point is too high, it indicates that the antifreeze has deteriorated and needs replacement.
