It helps if you go to AutoZone or some store like that and rent the O2 sensor sockets...they have a slot in the side so the socket slides over the cables.

But in any case, I believe its a 7/8" or 13/16"...I forget which one.

The nut on the O2 Sensor is a 22mm.

7/8 = .875 in = 22.2 mm, 22 mm may be the right size but 7/8 has worked fine for me in the past

Nine times out of ten a standard size wrench/socket will fit on a metric bolt and vice versa. It is that 10th time that gets you. I must confess that I have been in situations that have seen me use a standard tool on a metric fastener but I leave that up to the individual to decide. That is why I strive to provide the most accurate information that I can.

Make the O2 Replacement Easy

make life easy

remove the inner fender wells- about 6 screws and 5 minutes

disconnect the wire harness

use a 22mm or 7/8 box

no need for a special tool plus disconnecting the harness becomes much easier

I just used a regular sized 7/8 inch wrench. It was easy. The only thing I removed was the transmission dipstick tube. 1 bolt.

For future, I got an O2 sensor flex head wrench, that is like a 2 sided open end 22mm wrench.



Worked great, but now that I read the remove the inner fender wall trick, I might not need it any more.

The hard part for me was getting the plastic clip loose. The sensors were easy to unscrew with a regular wrench.

somedays life ain't fair

engineering is said to be a science of compromises
go fast- give up mileage/get good mileage -go slow
have headers and go fast(maybe)/ starter removal goes slow
