'undo'... if the radiator isnt too big why not tighten both valves, undo bleed screw and wait till it stops letting out water (10 secs or so), then you know its isolated and you can undo (crack lol) the nuts ON THE RADIATOR SIDE a bit till they dribble, catch the water in a shallow tray, when its empty you can fully undo these nuts and remove radiator, (carefull of carpets , the sludge in the bottom is like ink), take it outside and flush with hose if you can, then you can quickly undo valves with no radiator to check water is flowing through them (into bucket), this should sort it, tell you a lot about the state of the system or reduce that variable, IE if its all ok, then your problem is elsewhere, maybe that filter mentioned previously..
