How Antifreeze Works
Antifreeze is crucial for your vehicle’s cooling system. It prevents the engine from freezing in cold weather and overheating in hot conditions. But how exactly does antifreeze work? Let’s break it down.
Lowering Freezing Point
Antifreeze lowers the freezing point of the coolant. This means the liquid won’t freeze in cold temperatures. The chemicals in antifreeze, like ethylene glycol, mix with water. This mixture changes the freezing point. As a result, it keeps the engine from freezing during winter.
Raising Boiling Point
Antifreeze also raises the boiling point of the coolant. This prevents the engine from overheating in hot weather. The same mixture that lowers the freezing point also increases the boiling point. This ensures the coolant stays liquid even at high temperatures. Thus, your engine remains cool and efficient.
