Replace O2 (oxygen sensors) - 1992

[6speeder]

Anyone perform this task? No room for 7/8 O2 sensor socket on the right side, and socket will fit on the left side, but no room
for the drive. Can position a 7/8 closed-end wrench, but no room to swing the wrench. Maybe a stubby 7/8 wrench and a hammer might work,
but it is not in the tool box.

Internet searches, including videos of this job, are all straight forward.... easy, no problem.
Forum searches provided no info.

Would be interested to learn how members have achieved removal of the O2 sensor.

Thanks for the response, Hib....... The sensor socket I used was a 7/8" - 1/2" drive...... would not fit on the right side sensor, would fit on
the left side sensor, but no room for the drive. Is the 7/8" - 3/8" drive sensor socket that much smaller?

Hib, you may have been referring to this type of sensor socket:

CTA Tools 2065 Heavy Duty Oxygen Sensor Socket - Amazon.com

I was using a deep-wall socket. I have seen this type of socket, but didn't understand the application. Now I do.

Problem solved.

That be the tool. No doubt the mfg. of that tool sells them to Mac, CTA and likely others.

I bought that tool specifically to change O2Ses on LT5s but I use it for all O2s work, because it's so easy to use.

When you change the sensors, most of them come with a special glass-impregnated anti-seize lubricant. Make sure you use that stuff. Also, if you pull the old sensor out and find the threads are pretty nasty, I'd chase the threads in the sensor bung before I stuck the new sensor in there.

Lastly, the best O2Ses come from Denso. I think their design is better than that of Bosch or Delphi.

Thank you, Hib. A great deal of information written with a few words ........

Unfortunately, I already purchased the Bosch sensors...... at 81, I'm not looking for longevity.
