Jääkvedeliku

Jääkvedeliku, also known as antifreeze or coolant, is a fluid used in internal combustion engines and other heat transfer applications to prevent freezing and overheating. Its primary component is typically ethylene glycol or propylene glycol, mixed with water. These glycols have a much lower freezing point and a higher boiling point than water alone, providing a wider operating temperature range for the engine.

The main function of jääkvedeliku is to protect the engine from damage caused by freezing temperatures during winter. When water freezes, it expands, which can crack engine blocks, radiators, and hoses. By lowering the freezing point of the coolant, jääkvedeliku prevents this expansion from occurring.

In addition to freeze protection, jääkvedeliku also serves to prevent overheating during warmer months. The addition of glycols raises the boiling point of the mixture, allowing the engine to operate at higher temperatures without boiling over. This is crucial for maintaining optimal engine performance and preventing damage from excessive heat.

Jääkvedeliku also contains additives that protect the engine's cooling system from corrosion. These additives form a protective layer on metal surfaces, preventing rust and erosion. It is important to use the correct type and mixture of jääkvedeliku recommended by the vehicle manufacturer to ensure proper performance and longevity of the cooling system. Regular inspection and replacement of the coolant are recommended as part of routine vehicle maintenance.
