Also available at Autozone, Pep Boys, Checker/Advance/Shucks/Kragen for about $12
The one I got at Sears was cheaper than that!! I know I got out of there with the tool, and an extension to get back there, for well under $20. Otherwise I would have passed and gone with the tools I had

I just removed my O2 sensor when I had the manifolds off while putting the PEMs on... :P Much easier that way.

Like said earlier though, you can either spray the sensor the night before with PB blaster and then crank it off in the morning or you can change it out after you get home and the manifolds have cooled enough to touch them without getting burned, but still warm. Bolts and sensors come off easier at that point.

IIRC we took yours our while warm and the manifold was firmly attched to the block.

You guys are forgetting that the engine has to be reasonably cool because you have to get on top of it.

But yeah, if you don't want to buy the tool, you can clip off the wires and use a deep socket. Then you can just use a crescent wrench to put the new on it. You only have to tighten it to like 30 ft/lbs or something like that.

Dealer might have moved it enough to get an impact on a stuck O2. That would break more than had to be. :P

That'* my method, And I have an O2 sensor socket. No worries about breaking the socket (which I've done).
