The radiator is sized to keep the car from overheating under worst case conditions, say climbing a big mountain on a 100 degree day, or stuck in a traffic jam on a 90 degree day. That means the radiator provides too much cooling for the engine most of the time. The thermostat restricts the flow of water through the radiator to keep the temps high enough.
I don't understand your last question at all.
