Why are there air bubbles in my coolant tank?
There are air bubbles inside your cooling systems and they are being forced out of the system through the reserve tank. In theory, the system has to be airtight, but it won’t stay that way forever.
What to do if you have air bubbles in your Radiator?
Leave the radiator cap off, turn on your engine, and let it run until the radiator bleeds out air. It may take between 15 and 20 minutes for the engine to heat to the proper temperature and begin cycling coolant through. What happens if there is air in the coolant system?
Why are there bubbles in the overflow tank?
Problem Bubbles. Though it is completely normal to find bubbles in the overflow tank while the engine is not overheating, bubbles in the coolant could be the sign of a leak at the head gasket. To test for a head gasket problem, check each cylinder of the vehicle with a cylinder leakage tester while the engine is off.
Why is coolant Bubbling Under the head gasket?
EDIT: It has been pointed out that the bubbling could be coming from a leaky hose drawing air into the coolant tank. However, a leak that lets air in will also let coolant out; so you would expect to see a puddle of coolant under the car after a while. A leaking head gasket nearly always leads to an overheating problem.

What happens if there is a bubble in the radiator?
If bubbles are present during the test, combustion gas is leaking into the cooling system and this will need to be repaired. If left untreated, it could lead to a blown head gasket, which could leave you stranded. Geoff Hineman has been a professional writer since 2001.
How do you turn off the air bubbles?
There are plenty of guides to do this online. Once you have it jumpstarted, you can use the power switch on the back of the PSU to flip it on and off. 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.
