I have to replace the O2 sensor in my header, and I would really rather get the sucker off with out pulling the whole header.

I tried it today and it did not go well. I had the deepwell O2 socket, but because of clearance neither a rachet or a braker bar had enough room for me to try and pop it off. So I tried the other O2 socket I have, which is shorter and slightly different, but again I had no room to get it off with a braker bar nor a rachet.

So finally I tried an appropriat sized wrench, but I could not get it off (even after soaking it in PB Pentrating liquid). The only thing I can think of is maybe use a pipe on the end of the wrench for more leverage?

Any other ideas? Thanks in advance.

 

Turn the wrench counter clockwise.

 

Is that what you are supposed to do with it? I thought you were just supposed to hit the O2 sensor with it till it came off

Thanks for the bump though

 

I used a crescent wrench and a hammer. Put the wrench on and then hammer it in the correct direction and it gives it enough torque to break the o2 sensor loose

 

Good idea, I will have to give that a shot. Thanks much

 

no problem

 

yup thats what i did too.... pipe idea for a longer lever arm could work too.... wither way just make sure you don't round off the O2 sensor if its rusted intoo bad. liquid wrench liquid wrench liquid wrench

 

I unplugged that beotch (from the electrical connection above) because I couldn't unscrew it. Then I took it off having all the space and leverage. Screwed the O2 it back on to my new header then after it was installed, I plugged it back in.
