Oxygen Sensor Sign In

Where is the oxygen sensor located at on a '95 Chevy K1500 4.3L V6?

It's in the exhaust pipe, to the right of the transmission.

Re: Oxygen Sensor Sign In

Do you have any suggestions for removing a seized sensor?

Could I try spraying some PB on it? I wasn't sure if that would damage the new sensor once its installed.

Re: Oxygen Sensor Sign In

You can try whatever is at your disposal. Heat will, sometimes, work. But, gotta be real careful using it. Once you do get the sensor out, you can clean the threads in the exhaust pipe with a spark plug tap. (14mm, I think) Should be able to get one at most any parts store. Be sure to use anti-sieze on the threads of the new sensor before installing it.

Yeah, it took heat, a lot of heat! ha. I just re-taped it out and got the new one in with some anti-seize and all is well, thanks.

I don't think I've ever seen anything as seized or corroded as that sensor was.

Thanks again.

Re: Oxygen Sensor Sign In

Glad to hear you got it. Was just re-thinking my reply...18mm tap? The memory is definitely the second thing to go. sigh. It really is very common for those things to be siezed. Good job, and thanks for letting us know how it went.
