You can probably change it with a 7/8" or 22mm wrench, but they also sell oxygen sensor tools at that web site I posted. Of the three that they sell, the one I prefer is the shortest one. If there is enough room, the longest one may work slightly better.



Just to verify (as I might attempt this today) is this what you are talking about?



THANKS !

HAPPY HOLIDAYS ! ! !
