First, could you describe the sound? Also, are you sure the radiator is leaking or could it be the waterpump? THe water pump can make a clanking noise if it is bad, and it can leak coolant from a weep hole.
Now as far as the running problem. Did the engine ever over heat? If so, how badly? My concern is there is a possible headgasket problem.
LEt me know so I can better help you.
