Many reasons. It could be bad water pump, thermostat, head gasket, sensors, bad hoses, shot radiator. You need to give more info for an accurate diagnosis. feel your radiator hoses and if one feels hot and the other one is cold then you have a stuck thermostat. that will cause an instant over heat with the radiator still full.
start with checking thermostat
Check coolant level, and radiator fan operation.
There are many ways that it can overheat. Coolant loss, blown head gasket, stuck thermostat, clogged radiator ar only a few. You would have to consult a mechanic to know for sure why it is overheating.
It's the current flowing in a wire that causes it to overheat.
I have found the common causes for this are, a plugged heater core, and a poorly working water pump. The radiator could also be plugged.
