Coolant bleeding for Porsche 944/924S

This is the quickest way I've found to get air out of the coolant system.

1. Fill from the coolant hose, not just the expansion tank

2. Crack bleeder screw (12 mm)

3. Cover expansion tank fill hole with your palm

4. Blow into the expansion tank drain tube until you see coolant coming out the bleeder screw.

5. Close off bleeder screw, top off coolant in tank, and run engine for a few minutes (with heater on).

6. Repeat steps 2-5 until you verify your radiator fans kick on correctly and warm air is coming out of your vents

What do you do with the pipe that goes from the top of the tank to the radiator? When I try your method, I seem to just be blowing air into the radiator.
