Im trying to replace my LF O2 Sensor. I know where it is, I have the part, I have the socket, and I've tried getting it out numerous times. For the first hour, I couldn't get a ratchet to get up in the space. Then, I tried to use a rotating socket extension, and that seemed to be the way to go, but it wouldn't budge. I ended up breaking my ratchet. So I'm stumped as to what to do? Various places quoted me about $60 to change it for me (Yeah right, I already bought the part and everything). I was thinking about clipping the wires, unplugging it, and taking it somewhere and just tell them I need a bolt removed, that I had a hard time with it and couldn't get it on my own. When they go to do it, I'll point out that its the Oxygen Sensor... Hopefully they remove it for only $10 or so, because I can put the new one in myself easily. Anyone have any opinions on that, or any other tips? Also, where should I take it? Meineke? CarX?

 

dont think a garage would fall for the Need a bolt removed deal.. it is an o2 sensor and 99.9% of all micanics know what an o2 sensor is


Get a new wrench and more wd40 and hammer at it..

i didnt replace mine till i had the y-pipe off and even then it wasnt easy


sorry i have no other ideas for you
good luck...

 

Go buy a 1/2 inch drive o2 sensor socket and a good 1/2 inch drive socket wrench.

 

I have all the tools... I just can't get it. I do have the O2 Sensor Socket. Its at an awkward angle that makes it really hard to even make a connection between the sensor and the ratchet. Ive tried connecting the socket to the sensor first, then connecting the ratchet to the socket, and connecting the socket to the ratchet and putting the socket on the sensor. I just cant seem to get it.

 

Use a real penetrating fluid like PB Blaster or S'OK. WD-40 is a lubricant, NOT a penetrating fluid. Clean the threads as best you can, spray with penetrating fluid, and let it soak in awhile. Then try it with a breaker bar (1/2" ratchets are nice), or use a "cheater" pipe over a ratchet for added leverage. If still no go, repeat penetrating fluid and soaking, then try again (be careful, though. Too much leverage increases the odds of breaking a ratchet). Use anti-seize when installing the new one, but don't get any on the sensor part itsself.
