Many car owners hardly pay attention to their radiators until their radiators overheat. Fortunately, overheating episodes can be resolved or avoided by topping off the antifreeze levels.
As you know, engines create large amounts of heat as they run. Antifreeze runs through the engine to absorb excess heat. The excess heat is transported to the radiator where the heat is safely dispersed into the air. In short, antifreeze is directly responsible for keeping your engine from overheating.
