Hi,

when I screw the bleeding screw on Thermostat out, nothing happend and no water comes out...
Can I take a small thing to make the way free?

Just take the whole bleed screw out and see what happens.

Do you have the radiator cap off?

No when I do the radiator cap off, the engine gets warm then the water overflowing...
In upper hose there is nothing then air, and minimal coolant...

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...
