what is engine coolant

Engine coolant, also known as antifreeze coolant, is a liquid that is used to regulate the temperature of an engine and prevent it from overheating. It performs three vital jobs: it lowers the freezing point of the cooling system in winter, it raises the boiling point of the cooling system in summer, and it protects the engine and cooling system from rust and corrosion year-round. Coolant is typically a mixture of water and glycol, while antifreeze is pure glycol. Antifreeze doesnt freeze or boil as easily as water, so it's often used in high-performance engines that run at higher temperatures. Coolant, on the other hand, lowers the freezing point and raises the water's boiling point, making it ideal for use in car engines. The type of coolant required by a vehicle can vary by year, make, model, engine, and even the country where the car was made.
