Should Antifreeze Be Added in Summer?

Antifreeze should be added in summer. During summer, the engine operates at high temperatures, with normal working temperature limits often exceeding 100°C. Water boils at 100°C and is corrosive, which can lead to scale formation and affect cooling efficiency. Therefore, antifreeze is used to cool the engine. High-quality antifreeze coolant typically has a boiling point above 110°C, making it less likely to boil over in summer compared to water. The full name of antifreeze is antifreeze coolant, meaning it is a coolant with antifreeze properties. It is a specially formulated coolant containing additives, primarily used in liquid-cooled engine cooling systems. It provides functions such as preventing freezing in winter, boiling over in summer, and protecting against scale and corrosion throughout the year.
I've been driving for so many years, and I always add antifreeze in summer because it's not just for preventing freezing—it also keeps the engine from overheating and boiling in high temperatures. The engine operates at a high temperature, and the cooling system relies on coolant circulation. Without enough coolant or if the level is too low, it can easily lead to overheating or even cylinder head damage, which can be costly to repair. I recommend checking the coolant level in the radiator when the engine is cold to ensure it's between the MIN and MAX marks. If it's low, top it up with a professional antifreeze mixed with distilled water, and avoid using tap water to prevent scale buildup. This small habit saves hassle and money while extending your vehicle's lifespan.
