Make sure the engine does not have an air lock. If you just changed the thermostat you may have not gotten all the air out of the system and that is causing the car to overheat.

No air in system...that's the problem...The water going every where in the system...no air...there is some air going in by somewhere in the Intake??? don't no...i've try everything

It sounds like you have a blockage somewhere, and that the coolant can't circulate properly. A flush / fill might solve it.
