Well all you need is a 22mm wrench and some anti -seize grease.
Those are the items you will need. There are only 2 o2 sensors, one
bofore the catalytic converter and one located at the cat itself.
Find out which one is messed up and remove by inserting the open
end side of the wrench onto the sensor and REMEMBER LEFTY LUCIE
RIGHTY TIGHTY. Remove it and take the new sensor and put sup grease
on the threads hand tighten it till u cannot anymore and then
tighten it down with the wrench a little over snug tight. And that
is it you are done!
