Antifreeze Explained: What It Does And Why It's Needed
"Antifreeze" is a chemical, primarily consisting of ethylene glycol, which when mixed with water serves to lower the freezing point and raise the boiling point of the mixture. Traditionally, the combination of antifreeze and water is known as "coolant". As opposed to air-cooled vehicles which rely on fan-driven air blowing over engine components, water-cooled engines use a radiator, water pump, thermostat, heater core, hoses, and passageways within the engine.
