Kølevæsken

Kølevæsken, commonly known as antifreeze or coolant in English, is a fluid used in internal combustion engines and other heat-transfer applications to prevent overheating. Its primary function is to absorb heat from the engine's combustion process and dissipate it through the radiator. A critical component of modern cooling systems, kølevæsken is typically a mixture of water and ethylene glycol or propylene glycol. These glycols lower the freezing point and raise the boiling point of the water, ensuring the engine operates within its optimal temperature range under varying conditions, from freezing winter temperatures to extreme summer heat.

Beyond its temperature regulation properties, kølevæsken also contains additives that protect the engine's internal components from corrosion and erosion. These inhibitors form a protective layer on metal surfaces, preventing rust and the degradation of materials like aluminum and cast iron, which are common in engine construction. Regular maintenance and checking of the kølevæsken level are essential for optimal engine performance and longevity. Over time, the additives in the kølevæsken can degrade, necessitating replacement according to the manufacturer's recommendations. Using the correct type and concentration of kølevæsken specified for a particular engine is crucial to avoid damage.
