Answer:
The internal combustion engine has explosions inside of it regularly. Think about when you’re stepping on the gas pedal to accelerate quickly. How is the engine creating all that power for your vehicle to move faster?
There are an estimated 4,000 explosions taking place inside your engine every minute if you have a 4-cylinder engine and traveling at 50 mph. This is the process where the air and fuel mixture is ignited by the spark plugs to generate the power needed to move the wheels underneath your vehicle.
When you have so many explosions taking place this quickly, there is a lot of heat generated in the engine. These high temperatures could permanently damage the engine within minutes. The only thing which stops this from happening is the car’s cooling system.
The cooling system lowers the temperatures in the engine so that it doesn’t suffer any damage. Instead, it keeps the engine cooled enough to where it can keep operating smoothly.
Do not confuse the cooling system with the air conditioner because they’re actually two different systems in the car. The cooling system focuses specifically on cooling the engine, while the air conditioner focuses on cooling the people inside the vehicle.
If you had to choose which one was more important, then it would have to be the cooling system. You could possibly survive without air conditioning, but you cannot survive with a cooling system for your engine. If your cooling system doesn’t work, then your engine will die quickly.
