Rustbelt O2's

[rendyx]

Any thoughts on getting out my O2 sensors that will simply not turn? I've tried penitrant on the side of them I can access, and I've tried pounding the wrench I'm using with a hammer. It doesn't budge at all. Does anyone have experience wih rusted up ones?

If you have a oxygen/act torch you can remove them
easily. Heat up the y-pipe O2 threads dull red
and they will come out like butter. The hot wrench is a requirement when working on saltbelt SHOs.

Yes, heat will work well. I used a 1ft breaker bar to pop em loose.

I've had the same problem on the bolt holding on my alternator pulley and a bolt on my starter...impact wrench was the answer. thumbs_u

If you can't get oxy/act try a propane torch. Hold it for a longer time then try to open carefully.
