A few quick O2 sensor questions.
Hi All,
After doing some searching and reading on this site, I've decided to change the O2 sensor on my 1995 SLE. It'* never been changed and I have 133,000 miles on the car. I remember I used to get better gas mileage, but I never thought to change the O2 sensor. I have a few questions:
1) Does it matter if I get an AC Delco sensor or one from GMPARTSDIRECT. (I know to stay away from the Bosch)?
2) I can find the price of the GM part but not the AC Delco sensor. Are they similar?
3) The part numbers I've gotten from this site are:
AC Delco - AFS75
GMPartsDirect - 25312184
I just want to confirm that these are correct.
4) It sounds like the AC DElco unit comes with the anti-sieze compound on the threads. Does the GM unit come this way?
5) Can this change be done without the special tool to change the sensor? I assume, given its location, it'* easier to change the sensor from above (as opposed to accessing it from underneath the car)
Thanks for any help. I always like to get as much information before I embark on a job (as usual my brother has kindly offered to help).
Sincerely,
LeifW

It can be done with a good sized open end (or box end if you disconnect the connection first) wrench, but it is a much easier job with the proper socket. Some of the sensors can be a bit tough to break loose, so you'll want some extra leverage. If you don't want to buy one, I believe Autozone has a loaner. Yes, it'* easier to get from above.
