After replacing hoses and filling back up with coolant, you could leave the radiator cap off and start the engine and you should see bubbles from where the cap goes and coolant level drop. Turn off engine and fill with coolant and restart engine and repeat process until no more bubbles. Someone correct me if I am wrong, however, I’ve done this method before and seemed to work fine.
