Default Any tips for removing O2 sensor?

I tried removing O2 sensor with the special O2 sensor socket but it started stripping the nut part of the O2 sensor. Any tips on how to loosen the O2 sensor.

Default Re: Any tips for removing O2 sensor?

Assuming you have a six point version of the oxygen sensor removal tool, several days of liberal application of penetrating fluid, apply some heat to the manifold using a propane torch, say a quick prayer, and give one quick, firm twist of the socket. If it doesn't come out, or, strips further, you may be removing the exhaust manifold. Changing the ox sensors at the 30,000 mile interval is the best way to avoid this problem in the future. The same goes for spark plugs. You don't state what model car you have, I'm assuming the sensor is in the exhaust manifold. Good luck!

Default addon...

To strip the O2 head means that you are using one of the slotted sockets. Forget that tool and use it for installation only.

Get a sears (etc.) deep 6pt socket and a pipe/breaker bar and use that and the lubricant. I have a 5' bar for this and the axle nut. But, depending on your access, just get the longest bar that will fit.
