kylarvätskaantifreeze

Kylarvätska, often referred to as antifreeze, is a crucial fluid for the cooling system of internal combustion engines. Its primary function is to prevent the engine from overheating by absorbing and dissipating heat generated during operation. Beyond its cooling properties, kylarvätska also serves to prevent the coolant from freezing in cold weather, hence the common name "antifreeze."

The composition of kylarvätska typically includes water and a base of either ethylene glycol or propylene glycol. These glycols have a significantly lower freezing point than water and a higher boiling point, offering protection across a wide temperature range. Additives are also incorporated to prevent corrosion within the cooling system, lubricate the water pump, and inhibit the formation of scale and foam.

The concentration of glycol in the kylarvätska mixture is critical for its effectiveness. A common ratio is 50/50 with water, which provides a good balance of freezing and boiling protection for most climates. However, the optimal mixture can vary depending on environmental conditions and manufacturer recommendations.

Regularly checking and maintaining the level and condition of kylarvätska is essential for engine longevity. Over time, the protective additives can degrade, reducing the fluid's ability to prevent corrosion and maintain proper operating temperatures. Flushing and replacing the kylarvätska at recommended intervals, as outlined in a vehicle's owner's manual, is a vital part of routine maintenance.
