Best way to remove the O2 sensor on TBI y-pipe

Subject: Best way to remove the O2 sensor on TBI y-pipe Wed Aug 13, 2014 9:37 am

Ok so in the failing daylight last night I tried to remove the old O2 sensor. Looked like a 22mm wrench. with the long wire, I can't really get a socket on their and the FSM refers to a specialty tool for removal. The wrench I had was either hitting the steering column or the exhaust manifold so I couldn't get a turn on it......(not to mention probably 260K+ miles of heat to cement it in place.

I know a bunch on here have swapped it out, how'd you do it?

thanks

I cut the Y pipe out of the car. Might be a bit to extreme in your case though Wink

Btw, I'll have your O2 out today. Should be there by Friday.

Harbor Freight has O2 sockets, cheap.

And they can take quite a bit of torque and heat. Used one with a breaker bar on my friends POS Neon Laughing

Isn't the o2 sensor located in the manifold, not the pipe?

Top of the Y pipe.

I just so happen to have a 20% off coupon on my desk and a HF across the street from my office....I'll be stopping by after work!

Hmm. I seem to remember that the O2 on my 92 RMW 5.7 was in the driver's side manifold. Or, I could be crazy.

Thought mine was in the neck of the collector of the Y pipe. I'd check, but it's now in its new home at the scrap yard.

It's on the exhaust manifold just above where it bolts to the Y-pipe right next to the steering column

Lots of WD-40 the night before!

I'm not crazy! What a relief.

you know damn well you are crazy! geek

I used a crescent wrench to remove mine. Started it with the wrench, and turned it out with my fingers. Disconnect the wire before removing it from the manifold.

If only we all lived in a rust free zone!

Sprocket does.

Wagon came from Virginia so it's not as clean as a local, soaking it with PB blaster....

Don't forget... if you're replacing it, you can simply cut the wire flush and use a socket and a breaker bar.
