Does anyone know the AC Delco part # for the o2 sensor on a 89 5.7 GTA? I just bought one today, and was wondering if the guy gave me the right one. The part #'s on the one i got say ACD. AFS-20
and GM. 25162693. Also, are they the same for a 305 V-8 and a 350?
Thanks

Those are the same numbers that are on the one for my 90 formula 350.

 

Thanks Giovanhalen for the info. I am sure it must be the same part for a few years, and you have a 350 also. I feel better now. I just always think they are giving me the wrong part. God knows I have gotten the wrong part plenty of times!
Thanks again man.

I hate wrong parts. I was trying to get a MAT sensor for my 85 but they kept trying to sell me a MAP sensor. They were pretty dense.

I checked on AcDelco's website and it is the right part number for the direct orginal replacement sensor so you are good to go.

Thanks everyone for the help. I appreciate it. Hey Josh, I will have to check out AC Delcos site. I think that might be helpful.
Later guys
