help my radiator petcock is dripping.

after I drained my coolant and turned the petcock back closed it had the drips from the tube, do I need a new radiator or can I fix it some how.

Pulled the radiator and pulled the petcock out with a pair of pliers. it has tabs to keep it from coming all the way out. It had a torn O-ring so I replaced it and now it's fine

Thanks for everybodys help with this one and the fuel line post. I had to answer my own questions what good is that.
