Radiator Drain Plug
 

My plastic drain plug snapped in two. Jeez....believe it or not but all the local part stores in my area don't carry this. Does anyone know the size?

10mm ?

It seems everyone is saying that the "standard" for most cars is 14mm, which of course everyone has.

It's a pain :(

heres what you need correct?

they are metal with a rubber o-ring:

come in various common sizes.

Mine was plastic. Metal is okay? The one you pictured here looks like the one for my oil pan. This works for radiator too?

if you get the right size you should have no problems

yeah i think it's aluminum. i just cant remember the size. I'm pretty sure if you search miataturbo.net you'll find it. im too lazy to search for you.

Did you ever find what the correct size is? Mine got stripped and is now stuck in the rad. I'll try to drill it out but if that doesn't work then I guess I'll just have to get a new rad.

Try taking a Dremel/Rotary tool and grinding a new slot. Then take a much larger flathead, or even a quarter to unscrew it. If you accidentally hit the collar of the radiator spout, it’s not really a problem. It doesn’t seal there anyways.
