Question about 1999 Chrysler 300M
So you changed the thermostat?
Water will not circulate while engine is cold. As it reaches normal temp it should open and circulate. If it is overheating when warmed up, and still not circulating, then either the thrmostat is bad or wrong type, or it was installed wrong and somthing is blocking it.
One other thing possible is the water pump is broken, but usually when pump is broke, it leaks, from the back of the pump.
You could check the belt is correctly driving the water pump.

Tips for a great answer:
Since you have no circulation with the thermostat on-is it a new thermostat?- if yes,even though do not trust the thermostat, test him by putting him in a boiling water and with a thermometer,follow whether it operates on the temperature specified. Most probably does not respond.
