Car Forum / Nissan / Nissan Cars / June 2009'92 Nissan O2 Sensor replacement
Well, Rock Auto had a special on the O2 sensor for my '92 Sentra w/1.6L gas engine, so I said, "Why not? 177K it probably would not hurt." Except I cannot remove the old sensor. I've been spraying it with Liquid Wrench for about two weeks, and I went to remove it yesterday. No dice. I have a 7/8" O2 socket, but it doesn't get a good "grip". The corners are starting to round over on the sensor. The replacement sensor is almost spark-plug like, but the old one's flats are not as high, and it sits in another little plug (like a reducer bushing, which I presume is welded to the manifold) and there is not much room to get any kind of tool on it. I can live without the new sensor; I just don't want to break the old one and not be able to replace it. Any hints or tips?

I will try the freeze spray. The webpage links to www.tooldiscounter.com. It looks like they have all kinds of cool tools; anybody have any experience with them? I may order the O2 remover; I may have to do the 02 on my Hyundai as well (error code). Kill two bird.... I think I remembered how I dealt with this last time; I used a spark plug socket-fed the wire out the drive recess, and put a wrench on the flats of the socket. I think a thinwall 12 point socket would get a better grip on the sensor, the one I have is chamfered and doesn't really get much "bite".

You would be better with a 6 point socket. It would be less likely to round off the shoulders of the sensor, or bolts in general. For that matter, I don't know why they make 12 point sockets. The only reason I can think of is that there is less fiddling to get it on the bolt in cramped spaces. Anyone have a better reason for 12 points, rather than 6 point sockets?

Nope. 6-point is the way to go. When I changed the O2 on the '91 240sx for the first time at age 13, all it took was to cut the wire & use a good 6 point socket with a 2 foot cheater bar on the end of the breaker bar. It had rust-welded the outermost ring of the threads & the first 1/4 inch of the outermost thread simply broke off & came out as part of the old sensor. If the op has similar rust welding going on, forget about saving the old sensor. You need leverage. >You would be better with a 6 point socket.

There are very few justifications for 12 point sockets. If you are using a socket, you are using a ratchet 95% of the time, so the extra points do nothing but give you less grip. For the few times you use a breaker bar, 6 points are the way to go and the 12 point is definitely useless. The only exceptions are times when you really need a breaker bar and you just can't do the angle with a 6pt; or for 12 point bolts (there are some used on a few cars). TO the OP - if an oxy sensor socket won't do it, you can buy 6 pt deep impact wrench sockets and do it that way. You'll need to sacrifice the wires. >Well, Rock Auto had a special on the O2 sensor for my '92 Sentra >w/1.6L gas engine, so I said, "Why not? 177K it probably would [quoted text clipped - 14 lines] > > Any hints or tips?

If it's similar to a stainless steel hose clamp, I tried that already. But I don't think the socket is splaying open, I think it's riding up over the corners of the flats. Thank you, and correct me if I have misunderstood you.

Sorry yes Jubilee = brand name of British hose clip, used generically just like Hoover. All the O2 sensor sockets I've seen are full hex with one side cut out for the wire. If it rides over the corners then a 12 point will too. SignaturePeter Hill Spamtrap reply domain as per NNTP-Posting-Host in header Can of worms - what every fisherman wants.
