Are car coolant and antifreeze the same thing?

[LaHope]

Car coolant and antifreeze are not the same thing. The differences are as follows: 1. Coolant is not only used in winter but is required throughout the year. Whether in extreme heat or cold, a car cannot function without coolant. Proper use of coolant not only protects the engine's cooling system and improves heat dissipation but also enhances engine efficiency and extends its lifespan. 2. The full name of antifreeze should be antifreeze coolant, meaning it is a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head during cold winter parking. 3. Antifreeze is not entirely equivalent to coolant. Coolant is equal to water plus antifreeze. In simpler terms, coolant refers to any liquid that can cool the engine, which can be either water or antifreeze. Water is a very low-grade coolant and is also limited by seasonal constraints.
