kælivökva

Kælivökva, often translated as coolant or antifreeze, is a fluid used in internal combustion engines to prevent overheating. It circulates through the engine's cooling system, absorbing excess heat generated during combustion and dissipating it through the radiator. This process is crucial for maintaining optimal engine operating temperature, which ensures efficiency, prevents damage, and extends the engine's lifespan.

The primary components of kælivökva are typically a mixture of ethylene glycol or propylene glycol and water. Glycols lower the freezing point of water and raise its boiling point, providing protection against both freezing in cold weather and boiling in hot conditions. Additives are also included to prevent corrosion within the cooling system, lubricate the water pump, and suppress foam formation.

The concentration of glycol in kælivökva determines its protective properties. A 50/50 mixture of glycol and water is common and offers a good balance of freeze and boil protection for most climates. Higher concentrations provide greater freeze protection but can reduce heat transfer efficiency.

Regular inspection and replacement of kælivökva are recommended as part of routine vehicle maintenance. Over time, the additives can degrade, and the fluid can become contaminated, reducing its effectiveness and potentially leading to engine damage. The specific type and replacement interval for kælivökva will be detailed in the vehicle's owner's manual.
