1)Jack up the car
2)unplug the O2 sensor connector
3)unscrew the sensor with a wrench
4)screw the new one in
5)connect the new sensor
6)you are done.
I can't remember for sure what size of the wrench you need, but I believe it's 22mm.
Not counting the time it takes to jack up the car, the whole procedure should take 5 min or so. That's assuming that you can
get the old sensor loose right away. You might need some penetrating oil, and a wrench with long handle.

So does anyone know how to install the O2 sensor? I'm quite handy and I just need a general idea as to what to look for or do. I've replaced lots of stuff on my own already.
