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.

I have put in new head new radidtor when I put in thermostate water wont circlulate, when its out running fine Mitsubishi 03 l200 2.5

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.

Its possible and also that Thermostat was installed backwards. You can remove and test the Thermostat with a hot pot of water.

Sometimes you can get an airlock in the hoses and the water will not flow. You might make one last try and put on your heater to get the water circulating. A blocked thermostat will prevent circulation.

The only other thing you need to do is get the radiatior flushed. If your certain you have a good water pump and the thermostat was not put in upside down, then that would be the only thing left that would hinder water flow. If you have a follow up question on thei get back to me and if this was helpful a vote on the thumbs up would be greatly appreciated.

Window fogs up after driving for awile. Just

The mildew smell you refer to could be anti-freeze. When a heater core starts leaking it may allow anti-freeze (which circulates through it for heat) to be blown through the ducts onto the windshield in defrost mode. The repair is to have the heater core replaced. It may wait for the thermostat to open and allow the coolant to circulate before you notice it. Occasionally the carpet on the passenger side may be wet from leakage.

Coolant is not ciculating and not leaking it is blowing back in can i had new hose and thermostat housing put on is it air locked?

When engine is cold, take out the thermostat. Put back everything add water as needed to the radiator, leave the radiator cap out. Start the engine be careful stand in front of the radiator and where the radiator cap goes watch if the water is circulating rev it slowly and the water should circulate faster. If it is not circulating the radiator maybe clogged, inside the cylinder head where coolant circulates might be clogged or the water pump is not working.

1999 Chrysler 300M overheating

I am having the same prob. on 04 300m 83,000 mi. I am a chrysler tech and another tech at my shop had the same problem a week ago. Mine started when i Was on the thruway my guage crept up to 3/4 so i kicked the heat on and it went normal. After stopping I found the water pump went and was leaking bad. I replaced the waterpump timing belt and tensioner pulley. thought it was good untill on a long trip. Noticed temp goin up no leaks this time, coolant full. doesnt overheat with heater on. Actuated fans with DRB3 and both work and are working when car says its overheating. Replaced thermostat and bleed system. thought it was ok untill drove 35mi. suspecting bad wiring plugged radiator or coolant temp sensor. Still driving with heat on low to keep from overheating. any others fix this problem yet?
