In the internal combustion engine, the burning of fuel generates a lot of heat. For an engine, a little heat is a good thing, as it helps to vaporize the fuel, burning it more efficiently. Too much of a good thing starts to cause problems, if unregulated, so the engine cooling system transfers heat from the engine to the atmosphere, also the cabin on cold days.

It is the job of the coolant, a blend of water and alcohol, to accomplish heat transfer. In the engine, by the cylinders, engine coolant absorbs heat, which it releases through the radiator, but it doesn’t flow on its own. The engine coolant pump, typically referred to simply as “water pump,” keeps coolant flowing to manage heat transfer and engine temperatures.
