What are the functions of antifreeze?

[SanHarley]

Antifreeze has the following functions: 1. It provides anti-corrosion protection for components of the cooling system; 2. It prevents scale formation, avoiding the reduction of the radiator's heat dissipation efficiency; 3. It ensures the engine operates within the normal temperature range. The full name of antifreeze is antifreeze coolant, meaning it is a coolant with antifreeze properties. It prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head during cold winter parking. The boiling point of antifreeze typically exceeds 105 degrees Celsius, compared to water's boiling point of 100 degrees Celsius. Antifreeze can withstand higher temperatures without boiling (overheating), to some extent meeting the cooling needs of high-load engines.
