Recently I had to change the cooling radiator because it started to leak. What worries me is that it did not break due to too much pressure in the cooling system.
Is it normal when I stop the hot engine and open the expansion vessel cap to pressurize the hot water through the upper return pipe into the vessel accompanied by the sound of bubbling?
