The car's radiator and antifreeze are actually the same container, because what is added to the radiator is not plain water but antifreeze. Composition of Antifreeze: The main components of antifreeze are: 50% purified water, 40% methanol, and 10% other substances. Types of Antifreeze: Antifreeze is generally divided into three types: ethanol-water type, glycerol-water type, and ethylene glycol-water type. Can Different Antifreezes Be Mixed? It is necessary to use the same brand of antifreeze. Different brands of antifreeze may have varying production formulas, and mixing them could lead to chemical reactions between multiple additives, rendering them ineffective. How to Choose Antifreeze: The basic indicators of antifreeze are its freezing point and boiling point. On the market, antifreeze comes in several specifications with freezing points such as -15°C, -25°C, -30°C, and -40°C. Generally, it is advisable to choose one that is at least 10°C lower than the lowest temperature in your region.
