Need some help ASAP,

The radiator in my 87 305 ta has a plastic pitcock that is about 2" long with threaded diameter of stem about a quarter of an inch. When trying to find where my radiator was leaking I noticed that the pitcock was loose and would not tighten up. No matter how much I turned it, it stayed loose. It looks pretty mickey mouse. What the easiest thing to do to fix it? It's got a fork on the end of it and I'm not sure I can just put a screw in the hole...
Any advice will be appreciated!!

Thanks,
Dale

 

Sometimes you have to push them into the radiator and then tighten.

 

Those things work backwards sometimes, screw in to drain, screw out to seal.

 

I appreciate the help. I bought a new pitcock today and will see tomorrow if I can get it to tighten. Things aren't made like they used to be...
