Most modern cars have cooling systems installed in it. However, you should first know that despite the very fact that all cooling systems function the same way, there are two kinds of cooling systems that could be found in most vehicles. These are the liquid cooling system and the air cooling system.

The liquid cooling system can be found on most modern cars. A specific fluid is used to circulate throughout the pipes and other passages in the engine of your car. This liquid, or the coolant, absorbs heat in the engine, thus cooling it down. As per the air cooling system, this type is found on most older cars. Instead of the fluid used in the liquid cooling system, air is what is circulated around the engine. The air comes from a powerful fan which functions as the force that pushes the air through the engine.

If you do own a liquid cooling system, you should know that air and air bubbles could be found in the liquid that cools your engine. This may not be a big deal to you but remember that if this is the case, your engine could actually overheat. That is why it is important to remove any air in your coolant reservoir.

You just add to the radiator a mixture composed of half water and half antifreeze. Make sure you fill it right up until the top portion. Then, do the same to the overflow or coolant reservoir.

After doing such, just leave the cap of your radiator off and let the engine run. You would know that the radiator has already removed the bubbles because there would be a large air bubble come to the top or you would see the coolant go down. When this has been successful, refill the radiator with the right amount of coolant. And you can turn the cap of the radiator back on.
