My uncle bought a 74 Dart Sport a few years ago. The heat wasn't working so he took it in and had it looked at. They found a bolt shoved into one of the heater hoses. The valve on that car had gone bad and that was somebodies solution. Maybe a large ball bearing would work in your situation? Large enough so it wouldn't go through the valve?
you can make a plug by sawing off part of a large bolt, stick it in the hose,
and secure it with a hose clamp. Paint the clamp black, and won't notice it.
or you can put brass plugs in the water pump housing holes.
