Likewise, what happens if you have air in your coolant system? If you have an air pocket or “bubble” trapped within your cooling system, the coolant will not be able to reach and cool that section. You may exceed safe operating temperatures and cause a blown head gasket, warped head, damaged valves or pistons, a cracked engine block, a blown radiator or bursting hoses.

In this way, will cooling system bleed itself?

The coolant system can self-bleed some between the thermostat and over-flow tank, but to do it properly you should fill the coolant and run the car with the radiator cap off. Once the engine is up to operating temperature the thermostat will open and the air will bubble out. Top off the coolant as needed.

What happens if there is air in the coolant system?

When it cools, a vacuum is formed that allows atmospheric pressure to push the fluid back into the system. If there isn't enough fluid in the tank, air is pushed into the cooling system instead of coolant. A slightly low coolant level shouldn't cause much harm, though it may cause the car to overheat.

What causes airlock in car cooling system?

', however, in many cases the issue was found to be an air lock, created by air which was trapped in the coolant system due to insufficient bleeding during/after the installation process. The term 'air lock' is a generic term used to refer to trapped air, but the name can vary depending on the location of the air.

Do I need to bleed cooling system?

First off, yes you do need to bleed the cooling system after opening it. Bleeding means removing any air that is trapped in the closed system. Basically coolant is flowing through the engine picking up heat along the way. If there's air in the system that reduces the amount of heat the coolant can remove.
