Yes, only when I turn off the engine and it's starts about after two minutes and takes another 2-3 minutes.

I did as kosienutter said. Started engine with header tank cap opened, waited for the fans to turn on twice. Then I turned off the engine, I loosened the bleed screw. Everything was okay. So I took the car for a ride and after returning the same. Boiling again. Then I disconnected the turbo cooling and made a bypass. The temp gauge shows the same like before. After the next ride, basically calm. Only a few bubbles appeared in the header tank, but the strange thing is that the lower radiator hose was just cold and upper main hose was really hot. Tomorrow I will connect the turbo cooling back, try to remove the thermostat and drive the car again. And then? I don't know. The water pump? Radiator?
