Question radiator plug broke!

I noticed I was leaking coolant from the radiator plug, so I go to replace it and find it's half broken, so I can't get it out (it's the plastic kind you screw in by hand). How can I go about removing it? I was thinking about making two slots with a dremel tool deep enough to take out with a phillips screwdriver. Anyone have a better solution?

I don't understand why anyone would make these stupid plugs out of plastic...

To remove the problem of dielectric corrosion resulting in a VERY common leaking point on older vehicles which originally came with metal plugs.


As for removing it, go buy an easy out.

haha, I meant why plastic and not some other composite that doesn't break so easily, though I suppose a properly insulated metal plug would work just fine.

If you think plastic sucks when it breaks off just wait until you break off a bolt in there.

Besides, if you've got to tighten it so much that breakage is a common problem you're overtightening it.
