How old is the clutch for the clutch fan? I know when they get old sometimes they do not engage when they get hot. That was one of the problems on my green and white. That is why I only use flex fans. As for getting the air out of the system there is a tool that ataches where the radiator cap goes and they put a vacum on it. Longhorn Man should probably be able to tell you how and where to get it done. As for the radiator due you have a 3 row or 4 row. If it is the original harrison radiator it could be either or. My green and white had a 3 row in it and now it has a 4row.
