Occasional overheating, if not related to low fluid or other problems, is usually caused by a sticking thermostat.
coolant temperature switch turns on the fan, if the fan isn't running the car's overheating...it's a sensor mounted in the coolant line that detects coolant temp.
Try replacing the thermostat.
The engine will overheat violently, serious damage can occur if you continue to run the engine.
