The main functions of excavator antifreeze (coolant) include protecting the engine cooling system, preventing scale buildup, preventing boiling, providing corrosion resistance, and offering freeze protection.

Antifreeze, fully known as coolant, is a specialized liquid containing additives designed for the cooling systems of liquid-cooled engines. Its primary functions and characteristics are as follows:

1. Protecting the Engine Cooling System: Antifreeze helps protect the engine’s cooling system by preventing rust and corrosion in the water passages, ensuring the engine operates efficiently within the normal temperature range.

2. Preventing Scale Buildup: Antifreeze prevents the formation of scale, which can diminish the radiator’s cooling effectiveness and maintain the engine’s overall cooling efficiency.

3. Preventing Boiling: In high-temperature environments, antifreeze raises the boiling point of the coolant, helping to prevent the engine from “boiling over,” which protects the engine from overheating damage.

4. Providing Corrosion Resistance: Compared to plain water, antifreeze has anti-corrosive properties that protect the engine and its components from corrosion, thereby extending the engine’s lifespan.

5. Offering Freeze Protection: In addition to the above functions, antifreeze provides freeze protection, ensuring that the coolant does not freeze in low-temperature environments, protecting the engine from cold-related damage.

Therefore, antifreeze is crucial for the normal operation and maintenance of excavators and should be used year-round, not just in winter. Proper use of antifreeze can significantly enhance engine performance and longevity, ensuring that the excavator operates optimally in various environmental conditions.‌
