kølevæskens

Kølevæsken, often translated as coolant or antifreeze, is a fluid used in internal combustion engines and other heat-generating systems to transfer heat away from critical components. Its primary function is to prevent overheating, which can lead to severe engine damage.

A common type of kølevæske is a mixture of ethylene glycol or propylene glycol and water. Ethylene glycol provides a low freezing point and a high boiling point, while water is an excellent heat conductor. The specific ratio of glycol to water is crucial for optimal performance and is usually recommended by the engine manufacturer. Additives are also incorporated into kølevæsken to prevent corrosion and scale formation within the cooling system, as well as to lubricate the water pump.

The cooling system circulates the kølevæsken through the engine block and cylinder head, absorbing heat. This heated kølevæsken then flows to the radiator, where it is cooled by airflow before being recirculated. Regular checks of the kølevæskens level and condition are essential for maintaining engine health and preventing premature wear. Over time, the additives can degrade, necessitating periodic replacement of the kølevæsken. Different types of kølevæske exist, and it is important to use the correct type specified for a particular vehicle or system to avoid compatibility issues and ensure effective cooling.
