It's not true that a car overheats when the air conditioning is on. In fact, the air conditioning system in a car is designed to maintain a comfortable temperature inside the vehicle regardless of the outside temperature. The air conditioning system uses a compressor to pressurize refrigerant gas, which is then cooled down by passing it through a condenser. The cooled refrigerant gas is then expanded and passed through an evaporator, which absorbs heat from the air inside the car. The cooled air is then blown into the cabin of the car.
It is worth noting that when the air conditioning is turned on, it can put additional load on the engine. As a result, the engine may work harder and generate more heat. However, the car's cooling system is designed to handle this increased heat load and maintain an optimal operating temperature.
