I bought a replacement o2 sensor from Autozone tonight. They sold me the Bosch 13953 for my 351W. From what I've read by searching, this has worked for others, but it is not working for me. The Bosch o2 sensor is not threading in, yet the old one still threads in, is it possible it might take a different one?

I removed my old o2 sensor by heating up the y pipe and the wrenching it free with a large plumber's wrench. The tip of it broke off inside there, but I am not too concerned with it, should I be?

All O2 sensors, regardless of make or manufature are the same thread. If its just a PITA to reach, keep tryin.

good luck

I don't know if it's any different for the 302, but the Bosch part number for my O2 sensor was 15713 and it fit perfectly.

I would be a little worried about it wrecking your cats from bouncing around.

It's just an 18mm thread, the same used on old-school spark plugs. Get a spark plug thread chaser, spin 'er in, and it should clean up the threads like new. :thumbup If not, make sure your new HEGO has nice, clean threads. They can be messed up from the factory, however it's pretty unlikely.

I wouldn't worry about that old head to the sensor. When I put my Bassani Y on friday, guess what I found bouncing around in there, and the front cat didnt look damaged at all. It's definitely the one from the original oxy sensor that was replaced at about 90k, so it's been in there for almost 100k.

I seriously doubt AZ is the reason a Bosch O2 sensor isn't going in. Either the threads are defective on the new one or there is something fouling the threads in the O2 bung in the pipe. Look closely at the 2 side by side.

Hah, the same can be said about advance auto parts here in Cape May County... their computer "inventory" if you can call it that, is a total joke...

I call up on the phone, "Hey, you got a set of inner and outer front wheel bearings for a 92 ford bronco 302"
"Yes, we've got two of each"
"Is that what the computer says, or is that what's on the shelf?"
"We have them sir"
"Alright, thanks, be there in half an hour to pick them up, can you put one of each aside for me?"
"Will do."
*click*

I get there, and ask the same guy I talk to on the phone (recognized his voice) and he's like "Oh sorry, the computer says they're in stock but there aren't any on the shelf."

I lit that guy up, talked the manager, lit him up too about their inventory because it wasn't the first time this happened with me, and EVERYONE complains about that store in particular. And basically was given the old see ya later. I wrote two letters to corporate, and never received word back.

Most retail parts stores have become the Burger King and McDonalds of the auto parts world, and unfortunately has brought with it the exact same level of education/knowledge and pay.

i am pleasantly surprised when someone at pep boys/strauss/zone etc. knows anything besides stocking and mopping.
my counter guys at napa are old school, and know what they are doing most of the time.
its funny they have 2 different counters and computer systems. real parts at one, ricer parts at the other. its nice.

Yup, thats why I am no longer the Assistant manager of Advance Auto parts #650 in beutifull down town Lithia Springs Ga.

Anybody with any real sence will eventualy realize that working parts should pay more than $8.00 an hour. Especialy when your good at it.

And I was verry, verry good.

I was that guy that looked in the computer, If it wasn't there I looked in the book. If it was not there and you had the part with you I would go to where those parts were in the store and start pulling them out and comparing.

But the low pay and the district manager and store manager always riding my ass about spending too much time per customer drove me away.

Now see, it's guys like you that make driving out of my way to a parts store worth it. Just because the computer doesnt list it, doesn't mean the computer's right and it doesn't exist. Thats the usual response you get from the kids behind the counter... Oh sorry, not in the computer.
