Hey guys,
Does anyone know what size wrench i need to take off my 02 sensor?? This is the one in the 02 housing before the downpipe. I bought a 22mm but its too small. Any input would be great. Thanx in advance.

Go to Sears or some automotive store and buy an O2 sensor socket. The socket is a lifesaver.

 

All 02 sensors arent the same size diameter tho. If I can find out what size it is then i can buy the tool.

 

I was not able to get a standard o2 sensor socket to fit over the sensor in the 02 housing. I do have a megan o2 housing so that might be a reason why although its super tight in there in general. I would up using an adjustable wrench to get it out. You might try a crowsfoot o2 sensor wrench which may clear the area. As for the wrench size its 7/8.

 

Thanks alot!
