I am trying to replace the oxygen sensor on my 88 IROC with the 5.7TPI motor. I've tried various means to gain access to the current sensor but I can't seem to get a wrench on it to get it out.

Has anyone encountered this? If so, how did you get the sensor out?

 

They make a special socket for this...Not everyone uses it, but I have used it and it easily removes the sensor. Jc Whitney sells it. Do a search on thier web site...or your local auto parts store might also it.

 

yeah use a socket way easier, plus if you have to buy the socket you get another neat tool to add to your collection.

Thanks. I actually considered butchering one of my tools. Now I have the chance to buy a new one!

 

Keith,

Why butcher a tool that wasn't designed for the job? If you're replacing the sensor anyway, cut off the wire and use a standard 13/16" spark plug socket. When you install the new sensor, coat the threads well with anti seize compound and use a standard open end wrench.

I picked up a socket the other day for $11 at Auto Zone works great

Ahhh... Vader, you saw my dilemma. I didn't know there was a special tool for this and I couldn't get the open-ended wrench of the correct size into the area. So, I was going to cut my open ended wrench to fit... I now will simply buy this socket (I assume that's what it is).

Bosch was nice enough to coat the new sensor with anti-seize for me.

 

Vadar - Also, I did try my spark plug sockets, but they weren't deep enough. I even pulled the rubber out of them...

 

Make sure you get the old one warm, that anti seize is strong stuff. Running the engine for a few minutes will do it, just dont burn yourself on the exhaust.
