Turning on the heater allows the hot water and coolant to enter the heater core.The heater core is really just another radiator designed to extract the heat in the coolant and pass it on into the air surrounding it,in this situation the driving compartment,thus dropping the temperature of the coolant,thus cooling the over heating engine.
What else can I help you with?
Will turning off the AC and turning on the heater actually cool a hot engine?
Yes, the heater uses and cools hot water from the engine that would otherwise have to be cooled in the radiator. But, this only works if there is enough water to circulate. If your engine is overheating from insufficient coolant, the heater won't be much help. Turning off the air conditioner will always help. The air pulled in the front grille passes over the hot AC condenser before it gets to the engine radiator. The AC compressor also puts a load on the engine, so turning it off will make less heat in the engine.

Will turning off your air conditioning will it help to remedy an overheated engine?
Yes, turning off your air conditioning can help remedy an overheated engine. The AC system puts additional load on the engine, which can increase its temperature. By disabling the AC, you reduce this load and allow the engine to cool down more effectively. Additionally, running the heater can help dissipate heat from the engine by directing it into the cabin.
Would the radiator fan not working cause overheating?
Yes, if the radiator fan is not working, it can cause overheating of the engine. The radiator fan helps to cool down the engine by pulling air through the radiator to remove heat. Without the fan, the engine may not receive adequate cooling, leading to overheating.

If this happens, replace the water pump. It is usually convenient to replace the timing belt at this time.
