The radiator petcock valve seal is damaged. Check with the local auto parts stores for a petcock valve seal or a petcock valve replacement.

Either it is not tight enough or the threads are crossed.They are often made of plastic and damaged easily.I would say try to give it a fraction more turn and if no good remove it when the engine is cold and have a closer look If the threads are crossed it might be possible to replace it or apply some kind of sealant on the threads.
