Flushing your radiator really does nothing at all. If you have restrictions in the radiator, it's usually a hardened crud that isn't going anywhere and a new radiator is the only thing that's going to correct that. With the history of overheating, you could also have a blown head gasket at this point. You should get some chemical testing done on it.
