HELP, broken radiator drain plug

so your saying that the threads that are still inside my radiator will have room for a hex key?

probably, to be honest I didn't really look, I had the socket on there and then I heard a snap, got mad, and went inside.

the head of the plug was the part that broke off.

I'll go out and take a look in a few minutes

Thanks for the advice, im going out right now to take a peek, but there is almost no way to fit my head in there to even see the threads from the bottom.

I thought the coolant would leak all over the bottom plastic guard, so I took a few screws out (and broke one) and tried from the bottom. I also noticed that the radiator drain has a angled spout, is that where the coolant flows from?

Thanks for the tip, I'll use the same technique, only using water to flush everything through. I also have this coolant flush chemical I got from C-tire. I think my only hope for completing the flush tomorrow would be if canadian tire has the drain plug at the parts desk, otherwise I think everywhere else is closed..

thanks again
