Auto Cooling System vs. Air Conditioning- What’s the Difference?

Today we will talk about car cooling system, as many of you think that it is a single system which is working to regulate the temperature on both the engine and the cabin, but in reality the case is different. There are two cooling systems in your car. Out of these, one is used to keep your engine cool and the other one is used to keep you cool. Both of them are car cooling systems.

Car Cooling System

Your car engine is located under car hood, and it can produce a lot of heat. These temperatures are managed well with the help of cooling systems and also prevent your temperature gauge from moving into the dreaded red zone. The cooling systems haven’t changed much from the cars of the 40s and 50s. The basic idea behind cooling an engine is that it consists of a liquid engine coolant, which is circulated throughout the engine.






Your car engine must maintain an average temperature, it doesn’t matter if it reaches the triple digits or sinks below zero. Keep this thing in mind that if your engine temperature is too low, then would make your fuel economy to suffer and the emissions would also start rising. On the other hand, if it gets too hot then your car engine would lock up and your car would ultimately stop.

Car AC System

The car AC system is different. The main function of this system is to cool the interior of the car and keep the climate inside at a comfortable temperature for you and your family.

You will be surprised to know that your car’s AC system goes much deeper than the dials and the vents. It is divided into four different components. Have a look at them:

  1. Compressor- It is a belt driven pump, which is fastened to the engine. Its main function is to compress and transfer the refrigerant gas.
  2. Condenser- The function of this component is to take away the hot compressed gasses from the top of the condenser and then it cools them off. As the gas would cool, it condenses and exits the bottom of the condenser as a high pressure liquid.
  3. Evaporator- It is primarily designed to remove heat from inside your vehicle; it also acts as a dehumidifier in high humidity climates.
  4. Pressure Regulating Device- This part controls the evaporator temperature by cooling refrigerant pressure.

Keeping these systems in check

Now you are fully aware about the differences between these two systems. You will be able to perform necessary steps to check upon them and then both of them would be operational.





If you are experienced and have some basic knowledge of testing and repairing of cars, and have all the right tools, then you can perform some of the checks yourself. But if you are unsure, then it is a best idea to consult an expert to do it for you.
