  • Everything you ever needed to know about antifreeze and coolant

    CachedWhat is antifreeze? Antifreeze is a glycol-based concentrated liquid that you mix with water and use to fill up your car's cooling system. As the name suggests, antifreeze prevents your engine's coolant from freezing in sub-zero temperatures. What is coolant? Simply put, coolant is the liquid that runs through an engine to keep it within its correct operating temperature range. The vast majority of modern cars use liquid cooling to maintain optimum engine temperature. How does coolant work? The cooling system is a closed loop where the coolant is pumped through various small channels in the engine block and cylinder head, removing heat from the metal, before passing through a radiator. Isn't coolant just water? For the most part yes, though each car maker has its own set of guidelines, which you should strictly adhere to in terms of coolant specification and anti-freeze concentration.
