Ways to quickly cool down car temperature during hot summers



It is too hot to stay inside your car especially during hot summers. When your car is parked under the direct sunlight for hours, then it needs to be cooled down. You can try these 2 proven aerodynamic techniques to effectively cool down the temperature inside your car.

Open and close door ventilation technique (When your car is stationary)


  • Open one of your passenger windows. Open it all the way down.

  • Then repeatedly open and close your driver side door at least five times.

  • This will effectively draw out the hot air through your door and draw in the cool outside air through the opened window.

  • Now, the temperature inside your car could have been cooled down nearly to the temperature of outside air.

  • Before you do this, make sure the environment is safe to apply this technique.

Cross window ventilation technique (When your car is moving)

  • Open one of your back passenger side window and one of your driver side window.

  • Opening your car windows at opposite corners of the car creates a cross ventilation while your car is on the move.

  • Hot air escapes through the back window and cool air is drawn in through the front side window.
