The low coolant light is a sensor on the side of the radiator with a wire plug to it you can disconnect it and the light will go out and youll be back to having to check the coolant level,as for overheating, tack the thermostat back and replace with another one, it will open in boiling water but is it open all the way and at what temperature, can effect your cooling did it have red dexcool in it before, might need to flush out the cooling system,this coolant will clog everything up and go back to the green coolant I dont know whos brainstorm it was for dexcool.......that stuff is no good
Are you sure you burped the system of all air? Air in the system can stop the thermostat from opening and cause it to overheat.
