Changing Coolant + Removing Thermostat

["Alexander van Gerbig" <Audi_80@email.msn.com>]

    The procedure for getting all the coolant out of the car involves
removing the thermostat.  So I checked the Bentley and no procedure listed
but looks very simple.  There is what looks like a gasket or seal between
the coolant pump and the thermostat flange or maybe a seal inside with the
thermostat.  Does that need to be replaced, gasket?
    Also when I get the bumper off and get the thermostat flange off does
the coolant have a clean path to the ground?  Any more removing involved?
    To empty the whole entire system is removing that flange the way to do
it, or should I drain radiator seperately by removing the lower hoses, tell
me it all!  Also flush with water is good?

Thanks again!
