What is the purpose of adding antifreeze?

[DelAllison]

The functions of adding antifreeze are: 1. Automobile antifreeze, also known as coolant, is primarily used for cooling purposes, which is its fundamental role; 2. During vehicle operation, the engine operates at high temperatures. If the engine continues to work under high temperatures, it can lead to severe damage or even complete failure in a short period; 3. When antifreeze is added to the cooling system, the engine's heat is transferred through the cooling system. The heat is reduced before being dissipated into the surroundings, thereby cooling the engine and preventing overheating. Antifreeze has a higher boiling point compared to water, making it less likely to cause overheating in summer. Additionally, antifreeze does not corrode the engine's cooling system; instead, it provides anti-corrosion and rust-removal functions. High-quality antifreeze is made with distilled water and contains anti-scaling additives, which not only prevent scale buildup but also help remove existing scale.
