I started with an oil change and filter, then spark plugs and wires and air filter and water pump and clutch fan and three flush kits for radiator,and three thermastats, and a fuel filter, FREEZE PLUGS THAT WERE RUSTED OUT, AND NO HEADGASKET PROBLEMS AT ALL NO SMOKE ECT. Please tell me what i havent tried i was thinking maybe the ERG or the DPFE sensor or AIT sensor. The truck runs great not one issue except when i have to stop at a light or stop sign it starts overheating til i put the heater on full blast and it is too hot to keep rideing with the heat on.PLEASE HELP ME I CANT AFFORD ANOTHER CAR.

YOUR GOING ALL AROUND THE PROBLEM.I WOULD LOOK AT ALL BYPASS HOSES,ESPEC. AT THERMOSTAT HOUSING,
FOR A PLUGGED, LINE OR MANIFOLD EXIT, WHEN YOU TURN ON THE HEATER COOLANT GOES THROUGH HEATER POSS. BYPASSING THE BLOCKAGE,IN ALL YOU STILL HAVE TO LOOK FOR BLOCKAGE.IF RUST WAS IN SYSTEM. Also look at hoses when in this overheat to see if they are sucked in.

You need to have the cooling system checked for a blown headgasket.
