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 ~~is basically~~ a ~~one-way valve that keeps the coolant inside the engine and doesn't allow it to circulate through~~ the radiator while the engine ~~is warming~~ up. This ~~means that the radiator isn't cooling the coolant when it isn't necessary to do so, which~~ helps bring the engine up to proper operating temperature more quickly. As the engine temperature ~~rises~~, the thermostat opens gradually, ~~until it is fully open when~~ the engine ~~is warmed up~~. ~~This lets all~~ the ~~coolant pass into~~ the radiator ~~to cool and~~ then ~~cycle back into~~ the ~~engine~~.

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.

This schematic shows the components of the Ninja 250 cooling system and how they relate to each other.
