Is Car Antifreeze the Same as Coolant?
2 Answers
Car antifreeze is not entirely the same as coolant. Coolant is equivalent to water plus antifreeze. Coolant refers to the liquid that can lower the engine's temperature, which can be either water or antifreeze. Water is a very low-grade coolant and is also limited by seasons. The full name of coolant is antifreeze coolant, which is coolant with antifreeze properties. Whether in scorching heat or freezing cold, a car cannot do 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 service life. Engine coolant should be replaced every two to three years. However, if a higher-quality coolant is selected and there are no leaks in the engine cooling system, the replacement interval can be extended.
As someone who frequently tinkers with my own car, I've given some thought to the matter of antifreeze and coolant. Actually, antifreeze is just coolant with special additives, with the emphasis on the word "antifreeze." Plain water can only cool, but in winter it freezes and can expand and damage the radiator and water channels. Antifreeze, on the other hand, contains ethylene glycol, which can withstand temperatures dozens of degrees below zero without freezing. Additionally, it has a higher boiling point, providing better heat dissipation in summer, and it also prevents corrosion and rust. When I change the antifreeze, I make sure to use reputable brands—different colors represent different freezing points, and you should never mix them, especially with cheap products. Trying to save money might end up clogging the cooling system, and repairs will be a real pain.
