How Many Degrees Can -25°C Antifreeze Withstand?
1 Answers
Normally, -25°C antifreeze can remain unfrozen at temperatures as low as -25°C. The lower the freezing point, the better. The basic indicators of antifreeze are its freezing point and boiling point. Definition of Antifreeze: The full name of antifreeze should be antifreeze coolant, meaning a coolant with antifreeze functionality. Antifreeze prevents the coolant from freezing and expanding in cold winter conditions, which could otherwise crack the radiator or damage the engine cylinder block or head. Functions of Antifreeze: Antifreeze is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion year-round. Replacement Cycle of Antifreeze: For vehicles that operate for long durations, 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 avoid excessive foaming, which reduces the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-life antifreeze can remain effective for up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the antifreeze, it should be replaced promptly, and the system should be cleaned.
