I just got my Monte Carlo. The 02 sensor is bad on it. I've got a 02 Oldsmobile Alero that has the same motor, would it work? I'm not really a car person so I didn't know.

 

They "might". You would have to leverage an autoparts store web site and look at what is called the "interchange" (what other cars share that part). Sometimes it ends up being a cable length difference.

But in my opinion, for the trouble it takes to safely remove an O2 sensor that has been installed for a long time, buy a new one and move on. AC Delco is your best option with the O2 sensor. Some other brands (like BOSCH) have a history of not working right and tripping check engine codes.

 

I second the AC Delco.. I dont recommend the "cheaper" o2 sensors.. Ive had them give codes brand new..

 

I agree with The_Maniac and Wht02monte (hi guys) what do you all think of this website I found for AC Delco parts?

I have been using it lately and thought I would share it. I am always looking for original parts and part #s as I have had a lot of problems with aftermarket parts.
