Car over heating
2004 Chrysler Concorde LXI 3.5lt engine. with new radiator, water pump, radiator cap, thermostat, and bled properly. Also dye test performed on heads and block, no problem there is still overheating. What do I do next? Tired of process of elimination really costing way too much to figure out. Bought the car new, for 4 yrs everything was fine and all of a sudden started running hot.

How about the coolant temp sensor, and are the fans turning on?start by checking the coolant temp sensor,also is the waterpump belt installed correctly.also make sure the fans are good and also there fuses.
Sounds like an airlock in the heater matrix (heater matrix normally higher than radiator) have you tried top hose to heater....if not this and your not using water (venting out of expantion tank)try using a thermometer to check actual temp of water...last..poss temp sender to guage faulty/bad earth..?.
The sensor IS for the fans to switch on when hot
glad your sorted at last,glad to be of some small help....
Make sure the pump's belt is correctly installed. If it is double check thermo stat make sure its the correct one and properly installed. If thses items are A-ok then you have nothing to loose by having a repair shopdo a transfusion with a mfluid exchanger. You may have a blockage .If it is air lock other than getting a pressure tester that the dealers use to remove air lock the cheap way outis to run the car for an hour without the cap on It can't over heat cause there is no pressure and you'll see the steam vent out.
Have you changed the coolant temp sensor? that could be your problem. you may also want to see if your fan is turning on. if its not you may need to change the relay for that
you may want to change your water pump again. the one installed could be defective. also if your vehicle is not idleing correctly it will not allow the coolant to go through your system properly
