Is There a Difference Between Coolant and Water?

[OGavin]

There is a difference between coolant and water, and the difference lies in their functions: Coolant can prevent freezing during cold seasons when the vehicle is parked, avoiding the expansion and cracking of the radiator and damage to the engine cylinder block. Water, on the other hand, can corrode the radiator, produce scale, impair normal heat dissipation, and shorten the radiator's lifespan. Below zero degrees, water can freeze, leading to radiator damage and other consequences. Coolant is a liquid composed of antifreeze additives, additives that prevent metal corrosion, and water. It must possess properties such as antifreeze capability, corrosion resistance, thermal conductivity, and resistance to deterioration. It is not only used in winter but is required for use throughout the entire year.
