What causes air bubbles in a radiator?
Bubbling indicates rising air pressure in the cooling system, which is a sign that the flow of liquid is blocked by a pocket of air. One of the most common causes is a blown head gasket, in which the air pressure inside the cylinder heads is transferred to the cooling system.
What to do if you have air in your cooling system?
All you need to do is bleed the line and then refill it properly to ensure there are no air bubbles. There are a few signs you could be on the lookout for that you have air in your cooling system that can give you an indication of where to look when it comes to getting the problem fixed.
What’s the best way to get air bubbles out?
Your goal is to basically spin up the pump and send the air bubbles flying through the reservoir, turn it off as they do. Wait for it to settle for a few seconds and rinse and repeat. It helps to give the system a mild jolt, jumble, or jiggle while the pump is running to help some trapped air bubbles escape.
What causes air bubbles in a cooling system?
This is a result of the air bubbles leading to an overheating situation, and then coolant flowing through the line afterwards to get the temperature back down to where it’s supposed to be. This will continue to happen as air in the coolant cycles through the lines at random.
What should I do about air bubbles in my engine?
Let the engine cool down and add more coolant until you’re at the correct level. Give the upper radiator hose another squeeze to get any trapped air bubbles removed and then top up the coolant if necessary. Replace the cap, lower the vehicle back down, and take it for a test drive.

How can I keep air out of my cooling system?
Completely refill the radiator and the coolant reservoir again. They will be as much as half empty since earlier it was simply air that made it seem full. Seal the radiator with the cap. This will keep most of the air out of the system.
