I bought a bosch universal o2 sensor from autozone today and i was going to just crimp it up and drop it in. Unfortunatly the old one refuses to budge, I already tried liquid wrench, a pliers, even a crows foot but i just cant seem to find a tool that will break it free. Anyone got any suggestions on what tools\techniques to use to bust it free?

 

I hear heat works on that type of thing.

 

You did try an oxygen sensor socket right?

 

...wheres a blushing smiley face when you need it. I didnt even know such a thing existed, when i put the exhaust on the car i just used a 1in box end wrench considering the pre cat was out of the car when i did it. Where would i get an o2 sensor socket?

 

You can rent them from AutoZone, OReilly, or whatever flavor car parts store is in your local area...

 

thanks alot for the quick replies guys, the help is much appreciated.

 

Anytime...
hey that's what the forum is here for, right?

 

Start the Car first, let the Exhaust warm up a little, then use a O2 sensor socket. Hit it with a impact wrench if you need too.

 

Thx guys she came right out with that socket, even though i had to buy it and it was $10 =/ But the car seems to run a LOT smoother now, it used to kind of putter at idle put now its almost silent =D

I thought the 02 sensor didnt do anything at idle???
