Without radiator coolant, an auto engine would overheat extremely fast, leading to mechanical breakdown and engine failure. While oil may be the lifeblood of a carâs engine, coolant is like the water that helps to dispel heat. In fact, coolant mixes with water in a carâs radiator. It prevents the water from freezing and boiling given the extreme temperatures it is exposed to.
Quick Answer. Antifreeze and coolant are essentially the same thing. The Automobile Association (U.K.) uses the terms interchangeably or together (coolant/antifreeze). Antifreeze is colloquial for the chemical fluid ethylene glycol. Ethylene glycol and distilled water, in equal proportions, are added to radiators to cool automobile engines in summer and prevent freezing in winter.
