1990 735il radiator/thermostat replacement

ok. my car overheated. i took it to a reliable repair shop and they wanted $900 to replace the radiator and thermostat. thats what they figured was wrong. so i paid them the $150 for their time and figured i can replace them myself. i found both, brand new for $250. does anyone have any tips on the replacement of the radiator and thermostat. the radiator seems pretty straight forward. the thermostat seems different. any help will be appreciated.

Pretty straight forward, but go to http://www.nmia.com/~dgnrg/page_2.htm for some pics and text of this operation, both radiator removal (also check the link) and collant bleeding.
