Not sure what you are trying to achieve. The system will air bleed itself. Just put it all together. That spitting tube is a vent tube and won't flow coolant like that.

If you fix your leaks and still have air in to the system, there is a process you can go through to find the source.

Ahhh. I just had a similar problem. My issue ended up being a bad water pump. It was pumping air in to the system through a leaky outer seal.

More common sources of air would be a blown gasket or leaky siphon on the overflow tank. So, you should get to a point where you can pass a pressure test first and then make sure the overflow tube to the tank can hold suction. (As your coolant cools, it will contract and suck coolant back from the overflow. If the siphon is bad it will suck air in instead.)

If you prove that the system holds pressure and that the siphon is working, the only other source can be the water pump.
