Removing the heat created as a result of the change from the high-pressure change from a gas to a liquid. The liquid then moves through an expansion valve where it returns to a gas and then as it enters the evaporator.

Now fresh air is blown through the evaporator which then removes the heat (generated as the liquid becomes a gas again) and cool air is blown into the cabin.

Sometimes continues running of the A/C means and extra load on the car’s engine so it is advisable to put it off. If you leave the A/C on for a very prolong period of time in extreme hot climate it can be a cause of over heating.

  • Turn on the heater.

Turning on the heater also employs the same process through which the car air conditioner produces fresh air. Only that this time the process is reverse, turning on the heater blows some excess heat from the engine into the car.

The oil in the car’s engine does not only do the work of lubrication but it also removes 75 to 80 percent of waste heat. If the oil level is low then the cooling system might not be able to do the work of cooling alone. in addition to doing its other job of cushioning the moving engine parts.
