I currently have my car up on ramps to change the oxygen sensor , I am sure there must be a trick to teaching the almost impossible inaccessible nut , the final piece to removing the existing sensor, I have tried everything I can think of. The bolt is long and preventing me from getting the socket on , I have a 50mm socket but it’s too short , a 100mm , too long. Can anyone advise ?

 

Why not use an O2 socket?
Easy to find at any parts store too.

Two kinds available. I have and recommend both styles to give you options. There is NEVER enough room!




Or this kind.




Sometimes a plain old 7/8" box end wrench will work too.

Any hints on how to undo the plug on the end of the oxygen sensor lead ?!
