Sit back and watch this happen while enjoying a cold one, cuase in order to fully Burp your system the engine has to go through SEVERAL COOLING CYCLES........ I gave it the standard hour of running, if you still see air bubble comming out after that, check your overflow tank and make sure it has coolant in it.
Step 6

Why does my fan overheat?

The air bubble which gets trapped in the temperature sensor makes it nearly impossible for the sensors to report the accurate temperature. The sensor displays a lower temperature, which does not let the fan and cooling system turn on.
What is a cooling system passage?
Cooling system passages are designed to prevent air or steam pockets from developing. It's usually after a repair that this problem arises. It depends on the design of the cooling system. There are two types of cooling systems found on today's vehicles, the series, and the parallel system.
What is an air pocket in a cooling system?
Air Pockets in the Cooling System. Air pockets form in the cooling system after draining and refilling the coolant in the system. Air also enters the system while replacing the water pump or lower radiator hose. Sometimes even after the cooling system appears bled and filled, the engine continues to overheat. It takes monitoring and patience.
Can an engine overheat with air pockets?

You’re not going to be able to let just air out of the system. If it’s working leave it alone. If after running for awhile it stops cooling, then decide if you want to vac it down and refill.

If you do have trouble with it, then replace the drier and vac it down. The moisture in the air will be the biggest problem. It can freeze and create a blockage.
