1. Prevents Freezing: As the name suggests, it prevents the engine's cooling system from freezing in cold weather. Water expands when it freezes, which can cause the engine block to crack, leading to major damage.
2. Prevents Boiling: Antifreeze also has a high boiling point, preventing the coolant from boiling over in hot weather. This keeps the engine running cool and prevents overheating.
3. Corrosion Protection: Antifreeze contains special chemicals that protect the engine's metal parts from rust and corrosion. This extends the life of the engine and cooling system.
4. Heat Transfer: Coolant is designed to absorb heat from the engine and transfer it to the radiator, where it's dissipated into the air. Antifreeze improves this heat transfer process, ensuring efficient engine cooling.
5. Lubrication: Antifreeze also acts as a lubricant for the water pump, ensuring it operates smoothly and efficiently.
In summary, antifreeze coolant:
* Protects from extreme temperatures (both freezing and boiling)
* Prevents corrosion and rust
* Enhances heat transfer
* Lubricates the water pump
It's crucial to use the correct type and concentration of antifreeze for your specific vehicle. Check your owner's manual for recommendations.
