Antifriise

Antifreeze is a liquid additive that lowers the freezing point and raises the boiling point of water, preventing it from freezing in cold temperatures and boiling in hot temperatures. It is primarily used in the cooling systems of internal combustion engines, such as those found in cars and trucks. The most common type of antifreeze is made from ethylene glycol, which is a clear, viscous liquid with a sweet taste, though it is highly toxic. Propylene glycol is another type of antifreeze, which is less toxic but more expensive.

The primary function of antifreeze in an engine cooling system is to protect the engine from damage caused by extreme temperatures. In winter, if the coolant freezes, the expanding ice can crack the engine block, radiator, or other components. In summer, if the coolant boils, it can lead to overheating, which can also cause severe engine damage. Antifreeze works by lowering the freezing point of water to well below 0 degrees Celsius (32 degrees Fahrenheit) and raising its boiling point to above 100 degrees Celsius (212 degrees Fahrenheit), providing a wide operating temperature range.

Antifreeze also contains additives that help to prevent corrosion and scale buildup within the cooling system. These additives protect metal components like the radiator, water pump, and engine block from rust and degradation, extending the life of the cooling system. Over time, the protective additives in antifreeze can become depleted, and the coolant can degrade. Therefore, it is recommended to flush and replace the coolant at regular intervals as specified by the vehicle manufacturer. Disposal of used antifreeze must be done properly, as it is harmful to the environment and can be toxic to animals.
