 So you have a fan issue. Did you ever just hook a battery to the fan? So when you checked the impellor, did it spin when you kicked the motor? Did you try spinning it with your finger? The threads can strip, so they never push enough coolant.

 If the water pump and fan work correctly, no head gasket leaks and no water in oil or no oil in coolant. The only two things left is a blockage or air lock.

I’m starting to think it’s radiator as it bypassed thermostat and it’s running wen revs are up but shuts off wen you idle
