What could cause my 2007 Saturn Aura to overheat

What is your question?

My 2007 Saturn Aura is overheating change the thermostat are you still over heat to dangerously high then it starts to time it gets too hot and it goes from cool to dangerously hot within driving to block I'm not making any water or fluid what could be the problem

What makes this problem better or worse?

Nothing makes it better stuff to turn it off and let it cool down and what makes it worse is when the engine gets hot

How long has your 2007 Saturn Aura had this problem?

A few days was after I replace the serpentine belt
