Depends... If the hoses have been removed, then plug the side inlet with your hand or a rag and fill thru the outlet until it is full. Then 'unstop' the water inlet and it will quickly drain. Fill it again and then unstop it again. Then as they say, 'rinse & repeat' until it is flowing clear water.
Some of those Sealers are designed to have a Flush circulated by the Water Pump. A Model-A system partially works off of thermosyphon, so run the engine enough to circulate the cleaner. That is why we preface those flushes by using Dawn dish soap & water first.
