Anyone have a suggestion on how to replace the OS #1 Bank 2 on an 2005 2500. I think I have finally determined that it takes a 22mm wrench. I can only get the open end to get on the flats in one position and when I try to loosen the sensor the wrench seems to want to slip. Any suggestions will be appreciated.

 

How many miles on the truck? If more than a few, its probably on their pretty good. May take more than just muscle wrenching it off of there, like some sort of penetrant.

They also make some sockets for oxygen sensors that may be better at getting it off.

And for future reference:

Try PB blaster.Put some anti seize on the threads of the new one.

Thanks Jason I did not know there was a special socket for O2 sensors. Got one and solved the problem.
