Hey all,

Quick question: how hard is it to replace an oxygen sensor on a '95 Bonneville SE :?: Is it accessible without going under the car?

Thanks in advance,
Sasha

I would like to replace my 02 sensor,where do i find it on 1997 series 2? :?

One hint, run engine for a couple minutes to get pipe hot, then sensor comes out easier, you DO NOT want to break it. New sensor will come with anti-sieze on threads.

Don't burn yourself on the exhaust manifold!

Pffft...burns smurns. Cuts are what hurt, when taking the spark plug wire boots off to change the plugs. Ack! I get so cut up and still have not learned what gloves are for.

Or plug wire pliers....

the o2 for my 92 cost me about $10 i think.


in sharp contrast, they want close to $100 for a 91 civic.

Most O2'* for Bonnevilles should run 30 to 40. I personally reccommend ONLY AC Delco sensors. They're cheaper through www.gmpartsdirect.com if you're not in a hurry. I believe the 97 should have 2, one in the downpipe, and one after the cat. A crescent wrench works great.

The O2 sensors are 55.86 apiece, through gmpartsdirect.com

At least, they are for my 2000. I don't know if the same P/N'* apply for the '97, but here they are (you can thank DeathRat for these #'*):

The part numbers are as follows:
Pos 1 (In exh man) 25312203 & pos 3 (after cat) 25312207

Thanks for the help guys.
