Why Does My Car Overheat When the A/C is on?

 

If your automotive is functioning properly, Car Overheats When the A/C is On. The engine and cooling system square measure designed to handle the extra stress created by the A/C system underneath traditional conditions.

                                        

When you turn on your car’s A/C, the A/C mechanical device activates to push refrigerant through the system. As a result of the mechanical device is driven off the engine by a belt, it puts an extra load on the engine. Also, the temperature of the A/C condenser that sits right before of the engine’s radiator will increase once the A/C is turned on.

 



Underneath traditional circumstances, the strain obligatory by the A/C system won't cause the engine to overheat as a result of fan(s) mechanically activate to stay things cool. However, if the cooling system is already having issues, partaking the A/C could push the engine to the purpose of heating.

 

Common cooling system problems that can lead to overheating when the A/C is turned on include:

 

  • A weak water pump
  • An obstructed radiator
  • Cooling fan(s) not working properly
  • Faulty engine coolant temperature sensor

 

Also, although somewhat rare, a bad A/C compressor that’s difficult to turn can put an additional strain on the engine, potentially resulting in overheating.
