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.
start with checking thermostat
Check coolant level, and radiator fan operation.
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.
