Hi Brian,
    I had the same question as you as it didn't seem to do much when open or
closed.  When I replaced the coolant  hoses on my 86 I found opening the
thermostat bleeder valve allows air and or coolant  from the thermostat
housing to travel up the hose attached to it and  into the coolant  pipe
that sits around the  top of the engine.
