The first engines relied on thermosiphon cooling alone, where hot coolant left the top of the engine block and passed to the radiator, where it was cooled before returning to the bottom of the engine. Circulation was powered by convection alone. Other demands include cost, weight, reliability, and durability of the cooling system itself.
The energy used to heat the engine adds a cost. However, the savings in fuel generally outweigh this cost, especially if a timer is used to limit the heating period to about 4 hours before the expected start time. Taking the needed precautions, a kerosene jet-heater can also be used to pre-heat the engine. [2]

Coolant is heated in the engine, becomes less dense, and so rises. As the radiator cools the fluid, the coolant becomes denser and falls. This effect is sufficient for low-power stationary engines, but inadequate for all but the earliest automobiles.
