Oxygen sensor compatibility

[LamboSE5]

You have to use a blow torch to heat it up if it's seized into place. Atleast this is what I use to remove frozen O2 sensors. Your probably going to have to heat it up til it glows if its really that bad.

Thanks for that, at one point I though about that - forgot to ask, wasn't sure if that was an area I should put a torch to. Yea, it's really really froze in there bad.
-- When I heat it up, I assume I'm going to aim for this area I've painted in red, around the sensor? The exhaust piping, so that it expands away from the sensor? And not the hex part - the area I've painted in yellow? Right?

Is the sensor body solid or hollow? Can you get a 3/8" drill bit in there and bore a hole through it. Then use a rod or bolt, whatever to run through the hole to gain some turning leverage? Worth a try.

Good luck.

I like this idea too, thank you for the help. Though I think, at least without heat, it would just tear/twist the 'body' up and not budge the actual sensor any closer to being out. It really does seem like it's "fused" into the exhaust.

Looks like I'll be buying a propane tank this coming friday and trying again.

Thank you guys!

Your not trying to save the O2 sensor but you want to be easy with your front pipe there. Normally I'd heat up the area where the threading resides, you still need to turn sensor with your wrench. I had to fire mine up til it literally was glowing, then waited briefly before I placed my wrench to remove. Good wrenching and don't forget eye protection at all times.

Looks like I'm going to have to replace my o2 sensor less than a year later. I bought a NGK/NTK brand sensor from Napa auto parts but I guess my 850 doesn't like that brand. Nissans and Hondas usually like that brand of O2's in my experience. Any suggestions on what brand to get this time ? I was thinking about checking out what FCP groton or IPD is selling. Thanks.

Bosch is the only reliable way to go.

Get a cheap nut splitter. Put it across the oxy sensor and start to tighten down on to it.

Remove with a socket and an extension bar.

Bosch is the only way to go unless I want more issues. I guess I'm ordering a bosch O2 sensor. Good Look Bro.

I found a bosch 13877 O2 sensor for $15.44 on amazon, shipping as we speak. I don't usually trust Bosch because the the terrible quality of their spark plugs but I couldn't pass up this price. 4 wire sensor listed for a 2005 Neon.

Yeah it's weird, spark plugs and HT leads + Bosch = FAIL.

It's plug n play compatible for the volvo 850? Or you gotta use old connector?

No idea, I guess i'll find out. Crimping 4 wires isn't enough to scare me away from a good deal. The wire colors are the same, 2 white, 1 black 1 gray.
