	Now, imagine you get off the freeway and pull up to a stoplight. Your heat/water tank is full, because you've been generating a lot of heat driving fast. The cooling system was able to drain off enough heat to keep things under control as long as you were moving, but the tank filled up in the mean time. Now that you're stopped, the air flowing over the radiator is reduced to zero (which means your drain pump is down to zero pumping power). Suddenly, any excess heat at all (such as running the engine at idle) is enough to overflow the tank, because it's so full. The temperature gauge shoots up until the fan kicks in -- there's the drain pump stepping in at the last minute before the tank overflows. This situation (before the fan kicks in) is shown in the third diagram.		Now, imagine you get off the freeway and pull up to a stoplight.

	The thermostat feels the temperature of the engine and decides how much cool water ~~flow~~ it should be fed with, in order to keep ~~that temperature~~ stable.

The thermostat feels the temperature of the engine and decides how much cool water it should be fed with, in order to keep the engine temp stable. The thermostat keeps a minimum flow of water into the radiator while the engine warms up. This helps bring the engine up to proper operating temperature more quickly. (That's a good thing.)

			After the engine reaches the proper temperature of operation, the thermostat opens gradually, but only enough to keep that temperature in the engine constant, avoiding over-cooling.
			If the cooling of the water in the radiator is not enough, even when the thermostat is fully open, then the electric fan starts.

	In normal operation, assuming a system in correct working order and filled with coolant, the engine will remain at the correct operating temperature almost entirely through natural convection, as air moves past the radiator. The air moving past the radiator carries away heat, removing it from the engine. In some circumstances, the cooling system either doesn't receive enough air, or doesn't receive cool enough air, and it will engage the electric fan. This typically happens when the air temperature is over about 80° F (27° C), or when the bike is stopped or moving very slowly.
