Anyone know the thread size for a O2 Sensor?

I need to know what the thread size is for the oxygen sensor. I'm going to try and clen out the threads with a tap/die (Spelling) before putting in the new one. Just in case you need it. 91 Voyager 3.0.

Take the new one with you to the place where you will be buying the tool and they will be able to check it there and sell you the tool that you need

i believe its 14 millimeter !

Thanks guys, I took it down , they matched it up, I tapped it out and got er done.

be sure to put a little never seize on threads dont get it on sensor itself though!

Sorry I forgot to mention that, there was already a good load of it on the new O2 when I bought it.Now I know I shouldn't tell ya's this but it was a (Whispers) bosch sensor :)
