If the engine overheats while at a stop or idle only:
Most front wheel drive cars use an electric cooling fan motor located in front or behind the radiator. The function of the cooling fan is to improve airflow across the radiator at stops and low speeds. The fan is controlled by sensors that regulate the engine temperature and additional load that might be placed on the engine.
The air conditioning compressor will require the cooling fan to operate at idle as long as the compressor is on. A quick way to check the cooling fan operation is to turn on the air conditioner. The cooling fan should come on with the air conditioner compressor. Some cars will have two electric fans, one is for the radiator and the other is the air conditioner condenser fan. Usually the radiator fan is closer to the middle of the radiator. The radiator fan is responsible for engine cooling, and the condenser fan is responsible for increasing air conditioning efficiency at idle and low speed.
If your vehicle does not have an electric cooling fan on the radiator it will have a belt driven fan blade and fan clutch. This fan should be pulling a large amount of warm to hot air across the radiator onto the engine. What you want to determine with either fan situation is that there is ample airflow across the radiator at idle. The radiator is the primary heat exchange for the engine, and airflow is crucial.

Possible causes dodgy fan or temp switch, rad cap not holding pressure, thermostat could be stuck not opening up correctly causing it to pressurise the cooling system and then having air locks . Possible water pump weak circulation, Last resort head gasket on its way out or possible cracked head if there is a oil water mixture (creamy Colour) in rad or expansion tank then its down to head gasket. If u need more help then contact me

Either the cooling fan isn't working, or there is something blocking the flow to the radiator. Hope these help.

slack belt driving the water pump, the water pump itself, dodgy thermostat could be one of a number of problems, get it booked in and checked before you cook it.
