Most vehicles nowadays have what is called a closed cooling system, which means the coolant circulates only within the engine and never comes into contact with air. However, cars with older cooling systems may have an equalizer tube or hose connecting the radiator to the overflow bottle. Over time, this hose can become brittle and crack, allowing coolant and air to mix. When this happens, you will need to bleed the air out of the cooling system.
The first step is to check the coolant level and add more if necessary. Next, find the radiator cap and unscrew it. You'll need a clean cloth to catch the coolant that will come out when you open the radiator. Once the radiator is open, start the vehicle and let it idle for a few minutes. As the engine warms up, coolant will start to come out of the radiator. Once it starts flowing steadily, screw the radiator cap back on.
Next, locate the bleeder valve. This is usually a small knob or screw located on the top or side of the radiator. Turn the bleeder valve counterclockwise to open it and place the cloth underneath it to catch the coolant. Be careful not to get any coolant on your hands or clothes, as it can be harmful if ingested.
As the coolant flows out of the bleeder valve, air bubbles will also be released. Once you see only coolant coming out without any bubbles, close the valve and screw it tightly. Wipe up any coolant that may have leaked out and check the level again. Add more if necessary.
Your cooling system should now be free of air bubbles and ready to work efficiently. Bleeding the air out of the system on a regular basis will help prevent coolant and air from mixing and will keep your engine running smoothly.

What are the symptoms of air in the coolant system?
The most common symptom of air in the coolant system is reduced cooling capacity. The engine may run hotter than usual, and the heater may not work as well. The coolant level in the radiator may be low, and the engine may overheat. If the engine overheats, it may damage the head gasket or other engine parts. Air in the system can also cause the coolant to foam and the engine to overheat.

Frequently Asked Questions
What happens if air trapped in coolant system?
The engine may overheat and fail, increasing the risk of a serious accident.
What happens if you don't bleed air out of cooling system?
If you don't bleed air out of the cooling system, eventually the engine will overheat and it will result in a failed diagnostic code or even a car that won't start.
What happens if you get air in your coolant system?
If you get air in your coolant system, you will likely notice a loss of power and a fishy smell. If the air gets too bad, it can lead to an engine seizure or even complete destruction of the engine.
Will air work itself out of cooling system?
No, the air will not work itself out of the cooling system.
Do you have to bleed coolant after topping off?
No, not always. However, if the coolant level is low, bleeding may be necessary to avoid a system over-filling and possible failure.
