Oo. I am removing the radiator from '01 24 valve and am struggling with removing the radiator overflow and WS washer reserviors. It appears very straight forward but can't get them to move up far enough to remove them from their slots. Don't want to use the "bigger hammer" method and tear things up. Also, is the radiator drain valve just a 1/4 turn valve? It will only turn a quarter of a turn, but nothing happens??
