Used o2 tool, rounded out. There is no room to swing a hammer, going to have to remove the exhaust system. O2 sensors are worthless, and their locations are trash.
Very very useful information, I had to remove the Entire exhaust pipe and then put the pipe on the vice a lot more work this is very useful information thank you
I used penetrating spray and let it sit about a hour. But then I rounded off the sensor trying to use one of those "special" sockets, because it flexes too much and had too much slop in it. I finally got it to break free with a pipe wrench. Good luck!
Brake fluid works great for getting stuck 02 sensors off. If you feel the sensor seize up when your backing it out squirt some brake fluid on the threads and wait like 5 minutes and it’ll come out.
The trick to using heat to free a stuck bolt or nut is to put the heat on one part more than the other. So it would likely be better to put the torch on the O2 sensor rather than the exhaust pipe it sits in. Further, when you do put heat on one of the two pieces more than the other, it's the difference in temps between the two that cause the hotter one to expand more than the other one and that breaks the microscopic bonds that are holding them together.
Lol i'm glad you threw that last one in there i ended up stripping out the one on the manifold on my lincoln town car now i have to take the manifold off 😜
And if that doesn't work then sell the car.
used the o2 sensor tool. mf still rounded out cus thor himself torqued that damn thing

Thank you! I got it off using the grinder and socket suggestion with a big spray of PB Blaster.
You forgotten one. The one I used, a Pipe Wrench
This dude is a top g

Is it ok to run the car to heat up the exhaust while the sensor is unplugged?
Thank you for the options that gave me confidence keep bring real

Thanks, you have a very efficient presentation, lots shared in a short time. The Pipe Wrench is what did it for me. Thanks!

Stripped bolt remover?
Fire use fire 🔥
Maybe weld a larger nut to the base of the sensor,slip it over the rounded off part
👍
That happen to me the oxigen sensor bank ,one never the owner change it now no van put it out thing put teal hot can take out thank you video
