Should I Choose -25°C or -45°C Antifreeze?
1 Answers
In general, -45°C antifreeze is recommended for northern regions, while -25°C antifreeze is commonly used in southern areas. The market offers several antifreeze specifications with freezing points such as -15°C, -25°C, -30°C, and -45°C. The lower the freezing point of the antifreeze, the stronger its anti-freeze performance. Typically, you should choose antifreeze based on the local minimum temperature being at least 10 degrees lower than the antifreeze's freezing point. Precautions for using antifreeze: For private vehicles, replace the antifreeze every two years or 100,000 kilometers, and always use the same brand of antifreeze. If the same brand is unavailable, thoroughly clean the engine cooling system before adding new antifreeze. It is best to use the original manufacturer's recommended antifreeze. Some drivers use water as coolant throughout the summer, which can lead to scale buildup in the engine cooling system, potentially clogging the water pipes. Therefore, never directly add tap water. Instead, use distilled or deionized water. If neither is available, boiled and cooled water is still better than tap water. When adding antifreeze, pay attention to the MAX and MIN level marks on the antifreeze reservoir. If the level is below the MIN mark when the engine is cold, add antifreeze accordingly. The amount should be within the range between the MAX and MIN marks.
