Is Antifreeze Necessary in Summer?

[Molly]

Antifreeze is necessary in summer, as it is not just for winter use. Vehicles should use antifreeze all year round. Antifreeze is a coolant with special additives, mainly used in liquid-cooled engine cooling systems. It has excellent properties such as preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year. It also helps prevent corrosion and scale buildup, protects the engine's cooling system, improves heat dissipation, and enhances engine efficiency. Antifreeze replacement cycle: For vehicles that operate for long periods, such as taxis, high-quality antifreeze should generally be replaced once a year. For vehicles with shorter operating times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-lasting antifreeze can have a validity period of up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are found in the antifreeze, it should be replaced promptly, and the system should be cleaned.

I've been driving for over twenty years, handling everything from big trucks to small cars. Antifreeze is still essential in summer, not just for winter freezing protection. The main function of antifreeze is to raise the boiling point of the coolant. In summer, temperatures are high, and the engine tends to overheat easily. Without antifreeze, the water coolant would boil as soon as the cooling system is activated, leading to minor issues like stalling or severe problems like engine seizure. It also protects the hoses and radiator from corrosion and rust, saving you from expensive repairs. I check the fluid level in my own car once a year, and if the color is too dark or there's sediment, it's time for a change. Nowadays, there are long-life antifreeze options that last two to three years. With the added strain of running the AC in high summer temperatures, extra care is needed. Spending a few extra bucks on fluid replacement is far better than shelling out thousands for engine repairs. Don't slack on this—safe driving is what matters most.

As a regular driver who often transports family members, I place great importance on the use of antifreeze in summer. It's not just a product for cold weather. In summer, the engine is prone to overheating, and with the air conditioning running at full blast, the temperature rises quickly after just half an hour of driving. Antifreeze prevents the coolant from boiling and avoids radiator cracks or leaks. I check the fluid level every six months to ensure it's sufficient and prevent accidents. Corrosion is a hidden issue—once metal parts rust, repair costs can double. A friend recommended using hybrid antifreeze, which provides both freeze and corrosion protection at a good value, lasting a long time between changes. Simply put, high summer temperatures put a lot of stress on the car, and regular maintenance can save trouble and ensure safety.

I also mistakenly thought antifreeze was only for winter use before, but later learned it's indispensable in summer too. It raises the boiling point to prevent coolant evaporation in hot weather, extends engine life, and prevents rust. The cost is low – a single change can last two years, saving repair expenses and hassle. For short-distance driving with frequent AC use, lack of protection could lead to serious issues.

Antifreeze is absolutely necessary in summer, not just for its anti-freezing role. It raises the boiling point of the cooling system to a high-temperature range, as the engine under heavy summer loads can easily exceed 100 degrees Celsius. Without anti-boiling protection, it can lead to cylinder explosion and part damage. Anti-corrosion is also crucial, as radiator rust and leakage can cause vehicle breakdown. I recommend checking the fluid level and color annually, replacing it promptly if it appears thin or cloudy. Modern antifreeze offers long-lasting effects with simple and cost-effective maintenance. Neglecting maintenance can result in costly repairs of thousands for a single failure, not to mention the danger of engine overheating while driving. Simple habits can prevent major issues.
