Then please do NOT ask questions like above....


Have a nice life
Why the H*** wouldn't I if the parts in Tech Info are not as listed in the AC Delco catalog? The abbreviations of the parts aren't even close to the catalog.
You are right they arent..

We have done plent of reserch to make sure if people use the numbers in Tech Info that they will get the right sensor...

In 1993 there were 2 sensors... You must have a 3 wire heated O2 sensor on your car...

Others, Mostly the Supercharged from what we can gather used the Single wire unheated sensor...

If you can get a Delphi sensor I'm sure you will have no issues with it as they are a very large maker of automotive parts for GM... Good Luck..

And I wasn't trying to treat you like a Dumba**... Its simply called an O2 or Oxyogen sensor... Plain and simple..

Really? You mean there are people who haven't even heard the term "oxygen sensor" before? :shock: That'* sad.
I guess I am out of touch with humanity. Too many cars and computers. Not enough friends. :wink:

So now I know the part... This will be my first oxygen sensor removal, I know where it'* at, and how to get to it. The service manual recommends a special socket, some special anti-seize compound, and a torque wrench at 30 ft/lbs.
The torq wrench I know, but what do I look to buy as far as the special socket and the compound?
I wish someone would have introduced me to a torque wrench before I took my door panels off to put the speakers in... but that'* another thread. :P

The O2 socket is extra deep and has a cut in the side of it for the O2 wires to come thorugh while you thread it in.You should be able to get one at any chain auto parts store. As for the anti-seize compound, it comes in a small packet or tube and will keep the sensor from locking into place from the heat. Just try and find the high temp variety, the parts store that has the O2 wrench should have the anti-seize. Anti-seize is also good for your spark plug threads to make future changes easier.

On my 93 SE I was able to use an adjustable wrench on it, and not buy the O2 socket. It took a lot of repositioning though....

The service manual says the anti-seize compound should be electrically conductive. Should I still just use the high temp stuff? I thought it was supposed to be some special stuff, according to the manual.

Sorry if I keep prying for info, but if I'm going to do it, I'm going to do it exactly the way it should be done. Not that the suggestion was a bad one (I wouldn't know anyway), it just contradicts the service manual.

AutoZone rents the special tool from the Loan-A-Tool program. You pay for the tool in full, use it, then return it to get a 100% refund. I've used it multiple times.

You can use the antisieze if you like... When you get the O2 sensor, look at the bottom for a dark grey or almost black coating that should be on the threads as the AC Delco O2'* come with an antisieze coating already applied to the threads.. I have never has any problem removing one that was already coated from the factory..

If you were to remove the sensor at a later date, then yes it would be a good idea to use the antisieze before reinstalling the sensor..

The choice is your really being that this is a new sensor.. Good Luck
