Is it necessary to replace antifreeze in winter in northern regions?

[TannerFitz]

Antifreeze needs to be replaced in winter, as antifreeze is not divided into summer and winter types. Antifreeze: Automotive antifreeze coolant has the functions of preventing freezing in winter and boiling in summer, as well as anti-corrosion, anti-scaling, protecting the engine's cooling system, improving heat dissipation, and enhancing engine efficiency. Therefore, antifreeze is not only used in winter but should replace water for engine cooling throughout the year. Selection of antifreeze: Choose the freezing point based on the environmental temperature conditions of the vehicle. The grade of antifreeze corresponds to its freezing point, and generally, the freezing point should be about ten degrees lower than the lowest winter temperature in the local area.

Before winter arrives in the north, I make sure to thoroughly check the condition of the antifreeze. The main functions of antifreeze are to prevent freezing and rust. If the concentration is insufficient in extreme cold, it may freeze and expand, potentially damaging the radiator or engine components, which can be extremely costly to repair. I usually test the freezing point, either by using a small hydrometer myself or getting help from a shop, to ensure it's safe below -25°C. Generally, factory antifreeze can last three to five years without issues, but if the level is low, the color turns dark, or there are impurities, it's time for a replacement. I keep some concentrated antifreeze on hand for top-ups, which is both convenient and ensures safety. Winter driving comes with higher risks, and a simple check can save you from major repair costs. Don't skimp on this small expense—keeping your engine in good condition is what gives you peace of mind.

Years of driving experience have taught me that antifreeze isn't an absolute must-change in northern winters, but neglecting checks can lead to trouble. Once, I overlooked testing the concentration, and when a cold snap hit, the antifreeze froze, cracking the radiator and costing over a thousand yuan to fix. Now, I've made it a habit to check the freezing point every two years or after 50,000 kilometers as per the manual—anything below -30°C is considered safe. When adding new fluid, ensure it's thoroughly mixed; don't cut corners by adding water, as lower concentration means faster freezing. Testing it yourself is simple—just buy a tool and it takes about ten minutes. Regular antifreeze maintenance means worry-free winter driving, especially for long nighttime trips. Safety first—always remember that.

As an average car owner, I always prioritize antifreeze maintenance. Testing the freezing point before winter is crucial, especially in northern regions where lower temperatures require using a hydrometer to ensure sufficient freeze protection. If the fluid level is normal and the color remains clear without contamination, replacement isn't necessary; otherwise, top up with new fluid or concentrate to restore proper strength. The inspection process is simple enough for DIY, saving shop fees. Regular maintenance extends engine lifespan—don't wait for problems to arise.
