Antifreeze is a liquid used in a vehicle's cooling system to prevent the engine from freezing in cold temperatures and overheating in hot temperatures. It is mixed with water and circulated through the engine to absorb heat and keep it at a safe temperature. Antifreeze also helps protect the engine from rust. It is important to check and replace antifreeze regularly to ensure the cooling system works properly and the engine stays in good condition, especially during extreme weather conditions.
