Does Car Antifreeze Need to Be Replaced in Summer?
3 Answers
Antifreeze needs to be replaced in summer. Here are the reasons why antifreeze should be replaced in summer: Antifreeze's Boiling Prevention Function: Antifreeze has the functions of preventing freezing in winter and boiling in summer, as well as preventing corrosion, scale formation, protecting the engine's cooling system, improving heat dissipation, and enhancing engine efficiency. Therefore, antifreeze needs to be replaced in summer. Antifreeze Replacement Cycle: Antifreeze generally needs to be replaced every 50,000 to 60,000 kilometers. Otherwise, even in summer, if antifreeze develops issues, it can lead to problems such as high water temperature and clogged cooling passages. Therefore, antifreeze should primarily be replaced according to the recommended cycle.
I don't think car antifreeze necessarily needs to be replaced specifically in summer unless it's due for a change. The main functions of antifreeze are to prevent freezing in winter and overheating in summer, while also providing rust and corrosion protection. Under high summer temperatures, the engine operates under heavy load. If the antifreeze has degraded or failed, it may lead to a lower boiling point, causing engine overheating or even cylinder explosion. Generally, it's recommended to replace antifreeze every two years or 40,000-60,000 kilometers, rather than basing it solely on seasons. I often check the antifreeze level and color before summer - if it appears cloudy or drops below the minimum line, it's time for a replacement. Using a tester to check the freezing and boiling points is also quite simple. If left unchanged for too long, increased acidity in the antifreeze can corrode radiator pipes, raising maintenance costs. In conclusion, summer isn't a mandatory reason for replacement, but regular maintenance ensures driving safety.
In summer, when driving temperatures are high, the role of coolant is significant—it not only prevents freezing but also boiling. I make it a habit to check the coolant condition in summer, ensuring the fluid level is between the min and max marks. If the color turns brown or has a rusty smell, it indicates the need for replacement. The replacement cycle is generally around two years, not exclusive to summer. New cars might last longer, but older vehicles require attention. Poor-quality coolant can lead to insufficient engine cooling, making it prone to overheating and breakdowns during high-speed summer driving. Two years ago, I delayed replacing it, resulting in a broken fan and a thousand-dollar repair. The cost of replacement isn't high, and you can even add new fluid yourself using a funnel—just choose the same model. The key is to protect the car from rust and ensure hassle-free operation in summer.
