O2 Sensor Socket

[Houtman_imp]

Instead of paying $35 to $50 for a special flare socket, I have made my own in about 15 minutes.
Using a 17 mm 3/8 drive deep socket bought for $5 at Northern Tools and using painters tape to mark the area to be ground off, which I did with a 4.5 inch angle grinder.
Keep water on hand to cool the socket in between grinding to prevent bluing and losing its temper!!
It works perfectly. A damn sight easier then trying to add the picture for all of you to see my handiwork.

Great idea. Thanks for sharing!

I assume you need this tool only if you are changing exhaust systems?

Similar but different:

I've made a couple "banjo" wrenches over the years. That's a box-end wrench with s slot cut out so you can slide it over brake and fuel lines onto the coupling nut. They help avoid rounding the nut vs. a regular open-end that only grips two sides.

Super easy to make, worth the effort to avoid damaging those nuts.

Houtman, Good job. How long did it take for you to make?

I sucked it in and bought the Koken socket....

I went cheap and used an old wrench.

That's where the older 6-sided wrenches are better than the
newer 12-sided which kinda can slip around slightly and
cause an old rusty nut to strip out { get round }.

Props to cbfan for getting it out with that wrench. Mine was crazy tight and there is almost no clearance. I ate the $35 for the Koken.

Holy crap, that does look like a tight fit.

[cbfan_imp]

yep, tight but alittle liquid wrench and firmly holding down on the wrench got it out with no major dramas.
