Should you run a car without a thermostat?

You still have not explained "how you change" this path


I don't want to argue, I'm asking for REAL proof. I'm asking for an engineering reference (you SAID you are an engineer) to back up your claim THAT HAVING OR NOT HAVING A THERMOSTAT CHANGES THE PATH OF THE WATER FLOW IN AN ENGINE

I don't believe he said it changes the path of water flow. By having the restriction from the thermostat, along with the pressure in the system, water is forced into all areas of the cooling jackets.
Remove that restriction and the water goes from the water pump up through the heads and out the top radiator hose. Yes, it will travel to other areas of the engine but it is not forced through. Thus, it will remain in the rear of the engine longer than in the front, leading to higher temperatures.
Besides, if thermostats weren't necessary, I doubt Ma Mopar would have put them in the engines.
And, other one tidbit to remember, thermostats do not control the maximum engine temperature but merely the minimum temperature.
