On/Off Valve for radiator drain broke.

I was going to flush my radiator today, and I went to loosen the plastic bolt that controls the on/off valve, and the head of the bolt simply FELL OFF. I guess after 8 years, the plastic had dry rotted, and the head of the plastic "bolt" fell off, and the threaded body remained inside. I'm not entirely sure how I'm going to fix this, but I attempted already. I found a short, fat grade 5 bolt and put some JB Weld on the tip of it, and pressed it against the remaining broken plastic "bolt" hoping it'll cure, and I'll be able to unscrew it completely. If it doesn't cure properly, I'll need to wait til next week when the temps are in the 70s so the JB can cure better.

I'd like to replace this faulty plastic "bolt", preferably with something METAL. Does anyone know where to get a replacement, a better way to fix it than what I'm doing, or a better way to drain the radiator?

Are you talking about the drain plug on the bottom of the rad??

Where's this "on/off" valve you speak of?

You have to turn that plastic **** for the fluid to drain. The plastic **** that controls the flow is what I'm calling the "On/Off" valve, because that's essentially what it does.

6mm seems kind of small. I'm dealing with the inside of a broken plastic bolt. I may need to take pictures... it's hard to explain.

Mine broke off too years ago... used an allen wrench to tighten it and it's held through all my abuse for all those years.

So yea, I wouldn't worry about it.

You could probably "tap" it out whith a drill, then match the threads with a stainless bolt.
