obviously the only way to see if it works is to do it.....but yeah, i agree, i figured getting it good and clean with brake spray would be the way to go, if its going to work at all....

no 240 D radiators at the parts yard at the moment.....sucks, 6 months back they had an 85 euro 240 D, which has a BIG radiator, like a 300turbdiesel, and a comparatively massive oil cooler.....didnt have the money for that then though, and i didnt need it yet anyways....
