Acetone and transmission fluid ? I wish there was a way to put it in a spray can.

They put anti-seize on them, they usually come right out.

Take 'em out while the exhaust is hot. Last time I replaced one on my Liberty, about 1.5 years ago, did it while it was hot with a shot of PB blaster, O2 socket and breaker bar, it came out so easily.

No you don't, trust me on this. grin2

Hoosier makes a good point, get the slotted socket and don't use a wrench. I've never needed a breaker bar, all mine came right out with a ratchet.

Yes I wanted to use a regular wrench, but there's no room to swing it unless I remove the transmission dipstick tube. I didn't want to take a chance on breaking that so I ended up getting one of those crowfoot style sockets.

I think more important than the oil brand is allowing whatever you use the time to soak in and do itís job. A shot of even SuperTech penetrating oil has yet to fail me if I use it the day before removal. And if you do it while hot, donít forget the gloves and sleeves.

Spray it multiple times, over a 24 or 48 hour time period. That should help quite a bit. PB Blaster or any spray penetrator should work fine. All else fails, use a little heat. If it seizes and stops after it turns a little, turn it back in a little, blast it a few more times, wait, and commence process again. "Supertech" works fine!

I don't think the penetrating oil was doing a thing for me when I was working on my truck. The threads went too far into the cat and I am sure they were covered with 20 years of carbon. 2 came off effortlessly, but 1 had it's threads destroyed. $30 part.

Did the GM assembly guys in May of 1997 use anti seize? If so, how long does it last? I am unsure of both..

Just like kneegrinder said above: Hit them with PB blaster a couple of days beforehand. I like about three applications across up to three days, then they come right out for us...

None work very well on an O2 sensor or spark plug, the fluid cant get past the gasket. You can spray it for a year and the threads will still be bone dry.
The rust comes from inside and the amount of corrosion is dependent mostly on climate and usage cycle, areas of low humidity and have higher year round temps will usually have no corrosion problems. Cars operated in short trip cycles in colder temps can have so much corrosion and carbon it can pull the threads or break the sensor or bung.

Get a deep 7/8 6pt socket and long extension with ball swivel on your car, cut the wire off and use a breaker bar or impact gun set on a lower setting to hammer it loose, heat the bung only with a smoke wrench if its not moving.
Running the engine doesn't help much, similar metals have similar expansion rates, steel sensor shell and steel pipe are expanding together when both are heated at the same time.

I was just going to mention using torches. If you're replacing the whole sensor with a new one, why not use )))HEAT((( ? Unless you don't have torches of course!

I mean, if you are only replacing the exhaust part and need to reinstall the same O2 sensor well then, using a penetrating oil is the only way...or if you don't have torches I understand this, as I don't have them either! laugh
