crescent or something else?|||u can use a wrench, but your best option would be an O2 sensor socket. this will help prevent stripping the sensor and also protect the wires from damage. should be able to find one at a local parts store.|||An oxygen sensor socket.
Basically, it%26#039;s like a long spark plug socket, but it%26#039;s got a cutout on the side that you slip the wire and connector through so it stays out of the way. Any auto parts store should have the correct one.|||There is an actual socket that has a cutout for the wire...if you cut the wire on the old one..you can use a 13/16 spark plug socket to remove it..you can probably use a box end wrench to reinstall it|||If your going to replace the o2 sensor just cut the wire close to the sensor(its getting replaced anyway)and put the socket on it.|||actually 22mm not 13/16 lmao dnt use sae tools only metric or you will strip it out
