What brand of antifreeze is used in the Besturn X40?
2 Answers
The antifreeze used in the Besturn X40 is from the Great Wall Kunlun brand. Antifreeze is a special additive-containing coolant primarily used in liquid-cooled engine cooling systems. It offers excellent performance characteristics such as freeze protection in winter, boil-over prevention in summer, and year-round protection against scale and corrosion. Composition of antifreeze: The main components of antifreeze are: 50% purified water, 40% methanol, and 10% other substances. Types of antifreeze: Antifreeze is generally categorized into three types: ethanol-water type, glycerin-water type, and ethylene glycol-water type. Can different antifreeze brands be mixed? It is necessary to use the same brand of antifreeze. Different brands may have varying production formulas, and mixing them could lead to chemical reactions between additives, rendering them ineffective. How to choose antifreeze: The basic indicators for antifreeze are freezing point and boiling point. Market-available antifreeze comes in several freezing point specifications such as -15°C, -25°C, -30°C, and -40°C. Generally, it's advisable to choose one that is at least 10°C lower than the lowest temperature in your region.
My Bestune X40 was purchased last year, and the maintenance manual states that the original coolant brand is Kunlun Star. During the last service at the 4S店, the technician mentioned that Bestune uses -35°C ethylene glycol-based coolant, which is pink in color. Actually, the brand isn't the key point; the important thing is that it meets the manufacturer's certification standards. My neighbor replaced it with Great Wall coolant without any issues, as long as the freezing point is sufficient and different colors aren't mixed. In northern winters where temperatures drop below -20°C, it would be troublesome if the coolant fails. It's recommended to test the freezing point every two years and replace it if it's insufficient.
