Thermostat cooling system

Friends could you tell me if you have any negative impact over time to leave the cooling system without your thermostat? Since I have a Hyundai Accent for 2 years and I just realize that it does not have the thermostat and I do not know since working only with its temperature sensor. He never gave me temperature problems until the radiator fans stopped working that I suppose is due to damaged temperature sensor.

Greetings

Many mechanics choose to remove the thermostats arguing that they are inesins but it is not true the thermostat has the function of Acer The temperature changes in the engine and the radiator when the engine is hot the radiator is in cold the thermostat opens and passes the hot water to the radiator and the cold water of the radiator passes to the engine like saw the thermostat and the engine has an optimal work. Radiator have the same temperature so tell me it is easier to cool 5 liters of water or 15 liters, this because the 5 liters are in the radiator in a cold state and if you add those of the engine would be the 15 liters in total that is what I can tell you

Thanks for your jpabloca answer. I want to tell you that I did the test, buy the thermostat and install it. At the end of assembling everything I went out to make a small tour and the vehicle lost power and is totally unstable (bell or corcobea) to such a degree that I went out and I no longer want to turn on.

This day I will proceed to remove the thermostat and I tell you about the results !!

Friends, I tell you to remove the thermostat to leave the passage free of water but the inconvenience persists, I do not know what I could do to overcome this fault if someone can help me, welcome the comments.

I do not know what happened but of so much testing I downloaded the battery and desmos to recharge it and when it rides it again everything worked as if nothing ... I imagine that the computer had been stunned and when the battery was disconnected it was like a reset. That is what I think ...

greetings !!
