My Dodge Intrepid is overheating.

My Dodge Intrepid is overheating and I have no idea why.
My radiator was just replaced. Thought that was the issue because there was a hole in the side plastic. Radiator is now 2 weeks old, and I haven't driven the car because it still overheats.
My heater blows hot hot air so I don't think it is the thermostat not opening up. But then again the 02 Intrepid is supposed to have the thermostat on the cool side of the system, so I don't know if that would allow the heater to still work if the thermostat wasn't opening up. But I do believe that on my 02, since they some internet aritcles state that the design was changed, that the thermostat is on top. I had to replace the long water tube under the intake a couple years ago and I seem to remember the thermostat under the center housing.
There isn't any water in my oil, so the water pump seal is still good.
The car is running smoothly so I don't doesn't appear that the timing has jumped.
I am not sure if the catalytic converter is plugged, but the car has power.
Not sure if the TPS or wiring is bad.
And I don't know if the Temperature control valve would cause overheating if it was going bad.
Am in need of some serious input as to what could be causing my car to overheat.
I am car literate, so I will understand what you say.
Haven't been able to work for two weeks due to the car overheating, so if I get the answer that fixes the problem for my car, I will gladly donate then by submitting just a thank you note. Right now I can't let go of any money. Sorry. I should get points for being honest.
