So the Dashboard Gauge showing very hot (and alarm) does not guaranty that the fans will be told to turn on.
Can someone explain how the fans will turn on with the AC Compressor on, but not with the temperature sensor. A schematic would be helpful.
NOTE: The Fans did work correctly before I replaced the radiator, so I can believe that I broke a wire, or failed to reconnect a connector.
I also have a cheap bluetooth scan tool that works with the android torque app, if that will help. On my 2001 Chrysler van, that tool shows the coolant temperature in real time. I have never tried it with the neon, but I will give it a try tonight. I did not get a Check Engine Light, which I would have expected before the car boiled over, if this coolant temperature circuit was not working
