Did you purge the cooling system after refilling it? The cooling system would need to be purged from air pockets. This video shows how to do that... www.youtube.com/watch?v=xeTgmdRkQtY

im sure you replace the thermostate right.. also check to see if one of the rad.hoses are colasping...sucking closed...as said above get all the air out( theres a little trick,dill 2 or 3 small holes into the thermostate) as shown.and your fans are working right?


You have to get all the air out of the cooling system- or, maybe the problem wasn't the radiator anyway-
