Well, I screwed up. Laugh at me. I had the Ranger apart to change the passenger-side O2 upstream sensor because of a code, could not break it loose from the bung despite using Freeze-It penetrating oil, and managed to round off the hex with the sensor socket. The angle wasn't ideal for tool access because of everything around it, even though I had the fender liner out.

Will take it to a muffler shop. I'm guessing dropping that cat will be necessary to remove that sensor, and I might as well have that downstream sensor changed as well once the cat is out.
I usually don’t even try to unscrew them anymore without first heating the threaded bung to a nice cherry color with a torch. Run a threading tap down through when it cools and thread the new sensor in

So I’m out at the GFs for a couple days. Did a little adventuring yesterday and ended up a couple minutes away from Summit Racing so of course we made a detour. $325 later… lol. Bunch of bushings and -AN stuff and the cam positioners so I can change out the sensor and drive mechanism for the correct one for my green Ranger project

My credo
built, not bought
I've never understood why the oem cant clock the o2 sensor so its easier to get at...
My guess is that they installed it with no body there, just the engine & driveline in the chassis. They dont much care for the “down the road “ factor when something needs changed, just look at the 6.0 diesel super duty that needs the cab raised off the frame if the head needs pulled.

Too be fair, I hear it's quite easy to pull thr can on those trucks.

If you have a lift....

Most times when the standard O2 sensor socket won't get ya there... this style will.

Not sure how I got so lucky but when I changed the pre cat O2 on my '97 I used an open end 7/8" wrench to get it loose, 25 years and 170k miles and it came right out... was still Motorcraft so likely original... similar with the V8 Explorer I did a few months ago, 250k and 22 years and it came right out, that one might have been aftermarket, I don't remember, I fixed the wires that had been rubbed on the front driveshaft, added some antiseize and put it back in...

For corrosion prevention reasons, the oxy sensor needs to be in the top 180* of the pipe, that is the fundamental reason they are up on top where they are hard to get at.

Not just corrosion but for condensation on the ceramic heating element... sudden uneven temperature changes aren't great for them...

That makes sense. But why arent they on the side at 90°? Then it would be easy to get a wrench on. Even 45° would work most of the time...
Ah well, it only has to be dealt with once or twice in a lifetime of the vehicle, maybe 3.

So, originally I was supposed to be home this morning but that got pushed back to tomorrow so I did a little junkyard shopping. Got a Lund type sun visor and a transmission cooler from an 07 F-150 that I think I can make fit in my Ranger instead of running two RBV coolers

Got the Ranger back from the shop already. I got off light. The shop used heat to get the bad O2 sensor out and also replaced the downstream sensor on the same side. My concern was labor to drop the catalyst or even having to replace the catalyst. With me furnishing the upstream sensor I had already bought, my bill was about $250, and the check-engine light is off. For the driver's side O2 sensors, when it's time, I'll take it back to that shop instead of risking the same adventure again.

All's well that ends well.

I drove it to a job interview. Then I drove it to several places looking for the proper tape to re-tape a wiring harness. Nobody carries tape for wiring harnesses.
