1. Lowering the freezing point: Antifreeze contains chemicals such as ethylene glycol or propylene glycol that lower the freezing point of the water in the radiator. This prevents the formation of ice crystals and ensures that the coolant remains liquid even at sub-zero temperatures.
2. Raising the boiling point: Antifreeze also raises the boiling point of the coolant, allowing the engine to operate at higher temperatures without boiling over. This is crucial for preventing overheating, especially in hot weather or during heavy engine loads.
3. Anti-corrosion protection: Antifreeze contains corrosion inhibitors that protect the metal components of the radiator and engine from rust and corrosion. These inhibitors help extend the life of the cooling system and prevent leaks or damage.
4. Lubrication: Antifreeze contains lubricants that help reduce friction between the water pump and other moving parts of the cooling system. This ensures smooth operation and prevents premature wear and tear of these components.
By combining these properties, antifreeze helps maintain the proper functioning of the cooling system, preventing freezing in cold weather and overheating during hot weather. It also provides protection against corrosion and lubricates the moving parts of the system, ensuring the longevity and reliability of the engine and cooling system.
