You're right, but the lower hose was really cold, as if the car did not even drive; as if the water in the radiator did not flow

well, I am afraid that something is blocking the flow of coolant or that I have connected something wrong. Maybe really air trapped?
It seemed to me that boiling so intensively in the header tank is not normal.
I have driven my other cossie (2wd) and there is no such issue. I can even open the tank cap and there is no pressure.
Thank you all for your advice. I will try to find the cause and write if I solve the problem.
