are the sizes different on certain brands? because the stickies say to use a 16mm but i just ordered a sensor on the phone and the guy said the new one was bigger then that and that the one im my car is to. so now im confused

 

i wanna say 7/8"...i find it easier to use open end wrench

 

I just use an adjustable....

 

i wanna say 7/8"...i find it easier to use open end wrench


thank you i was wondering why they sell those tools i didnt want to ask though thought there was some reason for it

 

well the 02 sockets are more of a PITA atleast for our cars...others they maybe easier for...i had 3 sensors changed in about 10 min using an open-end wrench...took me 5 mind to try and get teh socket on th right way so i said f-it

 

how tight should i tighten it?

 

Snug.

 

I had no problem with taking off the 02's when i installed my y-pipe, but the wire was a little bit hard to work with. just make sure to put lots of wd-40 on it to loosen it.

i used an 02 sensor socket.

 

werd up, the 02 wrench is hard to use on our cars, i just use a open end wrench. if you dont know the size when your buying them size up a wrench while your there.

 

The O2 sensor should be tightened to 30 - 40 lb-ft. Isn't it a 19 mm wrench. I like using the metric system.

 

22mm I think

 

the sockets that u can rent are a piece of CRAP!!! i use a adjustable wrench

 

wouldnt an o2 sensor on a NISSAN be met. ?

 

ding ding ding!
its 1mm larger than the lug nuts.
its the same size as 98/99 strut mount nuts.

 

Thank you. I still dont understand the usefulness of 7/6th or 15/16th, verus 14mm, 15mm. I just dont get it...

Metric just logically makes sense. . . but dont let me ramble on.

 

well it makes sense to me too mm = more accuracy than 1/16th of an inch....but thats just what i used because it fit perfectly for the o2 sensors i had...i figured they would be metric too

 

That's why the adjustable wrench comes in handy sometimes when you're too lazy to figure it out.

 

7/8" (22mm). My $80 Snap-on O2 sensor wrench takes them right off

 

Yeah, and it's an $80 O2 sensor wrench....

 

Here are the two that I have. The crow's foot type is the best and easiest to use. It was around $10.

 

I have a 02 sensor socket. Its really easy. If you need it, PM me..

 

Jime where did you get the crowfoot o2 sensor?

 

Don't forget to use anti-sieze on the threads when you put it back on.

 

Got it locally at a Canadian Tire store. Here is one on Ebay starting at $5.

your local auto store (kragen, autozone) should have them. You can borrow it from them for free.

 

I have the standard O2 sensor which is the first socket in the picture, but the second one is good for those hard to reach spaces. But, I guess also the adjustable pipe wrench will work. I allways find them usefull for stripped nuts.

 

like i said open end wrench......unplug it.....pull the wire down....loosen and twist.....when u get it open end wrenches that big...they usually have plenty of torque
