How would air get trapped in a sealed cooling system?
Causes of Trapped Air in Cooling System A car’s cooling system is closed and pressurized, with the radiator cap retaining this pressure. If the radiator cap fails, however, coolant may escape and air may enter; thus, leading to trapped air in the cooling system. Leaking radiator hose. Leaking heater control valve.
Can air pockets cause coolant loss?
Air pockets causes a lower coolant volume, often leading to higher than normal operating temperatures. Air will be seen bubbling from the radiator inlet neck or inside the expansion reservoir.
How do you know if there is air in cooling system?
If it’s cold and you’re trying to keep your vehicle warm, you’ll notice that the air blows warm sometimes and not other times. This is a symptom of the coolant system having air in it.

How can I get air pockets out of my car?
Air pockets are typically removed with patience, and depending on the vehicle, a special procedure or tool. Technicians can use a coolant fill funnel or a special tool that forces coolant into the system. Air rises to the top of the system and is more compressible than coolant; it can be difficult to remove without a special procedure.
What happens when you remove air pockets from car cooling system?
Air pockets can be stubborn, and the engine will continue to overheat until the air is removed. Air rises to the top of the system and is more compressible than coolant.
Why do I have air pockets in my radiator?

What to do when air comes out of car cooling system?
