I have a 1996 4.6L GT, I recently replaced the motormounts, heater core, waterpump and thermostat. I flushed the radiator before doing all of this. Now the only problem is the system keeps giving me a low coolant light, and runs hot even when in idle, even though the resevoir is full. The thermostat works because i can feel the coolant going through the upper radiator hose. Im going to check my fan when i get off work today but that shouldnt give me a low coolant light. Any suggestions would help thanks..

Im going to try and replace the coolant temperature sensor and level sensor

 

yeah try and replace the sensors. i hope you dont have the same issues i had, i eventually had to go to a manual temp gauge due to electrical issues.

 

check Electric fan main amp fuses should be a 40 or 50

 

I would try burping the system again, you simply may just have a nasty air pocket causing you some problems.
