The trick to using heat on situations like this is to be able to heat the
outer nut fast enough for it to expand before the heat also expands the
inner part being removed. Do be aware that if the threads gall you may need
to replace the catalyst. Before doing this job at the very least have an
18mm spark plug thread chaser handy or a tap. Some additional nickel base
anti size on the threads will help next time. Be absolutely sure none of
that gets inside or on the sensor end. Anything in there will contaminate
and ruin it.

Well, first attempts with a 22mm box wrench and heat have failed. Should I
break it off and use a regular 22mm socket?  Get a 7/8" special O2 sensor
socket, which is slightly larger, so I can put a long bar on it? Take it to
a muffler shop?



Other ideas?



Thanks!
