Got the same issues here
I replaced the radiator and thermostat flushed it out had a pressure test done and it held normal pressure. Checked oil and plugs to see if head was bad all is good, the fan comes on when it suppose to. I have gone thur the whole cooling system. If I run the heater temp will drop to normal. I even used K&W sealer to seal any internal problems, still no luck. HELP!!!!!!
