Can someone please tell me the correct socket for removal of the sensor.How deep does the socket have to be and where can I find one.I saw one advertised on the web for $10 but I forgot to bookmark the site. Also,I have the replacement part with the adapter connector and am wondering if the whole thing fits inside the socket itself when either removing or installing.

 

I just use a crescent wrench and it works fine. No need to buy an expensive tool that you will hardly ever use unless it makes a job significantly easier.

 

A crescent wrench is usually not good enough. It would be if the sensor was replaced at the right intervals and anti sieze grease was used, then sure, a crescent wrench is the best idea. However, most of the fc's are abused, and like mine, the sensor had 'never' been changed.
It was siezed in there extremley well.

If that is the case, and its too hard to get out with a crescent wrench, youll need

o2 sensor socket (you can find this at any autmotive shop, around 12$cndn)
Socket extension
Socket driver (good one)
Pry bar of some sort, something to give you leverage.

You can try pennetrating lube like WD40, but for me it did squat. I'll never forget it, my dad was up ontop of the engine bay, squatting so his head didn't hit the underside of the hood, and he's tugging and tugging at this socket driver trying to get the o2 out. It was the funniest sight ever, like as if you gave the wrench to a strong ape, he'd probably do the same thing lol. We didn't have a pry bar, so it was alot harder, twisted one of our extensions right off.

I had to remove the exhaust manifold, use an O2 sensor socket, and a bigass breaker bar, PLUS a lot of PB Blaster.

I've never had a problem ever removing my o2 sensor and never use antiseize. Maybe I'm just lucky or really strong haha.

 

The trick is getting the exhaust warm before you try to bust it loose...

And with the correct socket, a couple of 1/2" drive extensions, and a breaker bar, it's a breeze...

 

I've always gotten lucky with a regular wrench, Or if you are removing the sensor to replace it , then i sometimes will just cut the wire close to the sensor, so i can fit a socket over it, and then tighten the new one with a wrench. Don't forget to use anti-seize on the new sensor.

i just smack the old one with a hammer to break off the sensor part and then i can fit a regular socket on it.

 

ha thats a good idea

 

22 mm wrench.

Or you can get a special 02 sensor socket. You local auto parts store will have them.

You can generally use a 10 in cresent wrench. There is a decent amount of room to work with.

 

I use a 7/8th inch crowfoot. I don't use it for anything else just the 02 sencor.

 

Best idea yet. I was able to manhandle mine with a crescent when I changed it, but I like Mint87RX7's idea.

 

The cheaper crescent wrenches will flex so it depends on the tools you have. Craftsman ones should be good, strike the end of it with a hammer or use another wrench on the closed end put the two together to increase leverage.

 

I had 2 oxygen sensor sockets, and lost both. Now I stick to the ol`trusty crescent wrench.

 

Would a faulty o2 sensor cause it to smell like gas..

 

Go to your local Advance Auto. the one by my house loaned me a brand new one for free. Nosence in buying a tool you likely never use again. Just ask me, I have a tool box full o one use tools.
