There is a bolt on each cylinder to drain fluid that otherwise will get caught in the water passage. This is to drain what would not normally come out using just the main and radiator drain plugs. One pic below shows one with the bolt already removed and the other still has the bolt in.
The last pic shows about how much fluid to expect coming out.
