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.
The method used to warm a car's cabin isn't a whole lot different from the one used to keep its engine cool. In fact, it's all hooked together and runs on the same circuit. Coolant circulates through the engine and absorbs engine heat, which is exchanged with the outside air by way of the radiator.
