Just take the whole bleed screw out and see what happens.
Do you have the radiator cap off?
__________________ You made three mistakes. First, you took the job. Second, you came light. A four man crew for me? F**king insulting. But the worst mistake you made...
After 10 Minutes running engine water comes out the bleeding screw, then I run the enginge 20 minutes, and in last minute the reservoir was empty...
Hope for non bad since...
