How To Replace 2002 Cadillac Seville Upstream 02 Sensor Bank 1 Sensor 1

[@HardKnocksForge]

Should have taken you about 20 minutes to do that O2 sensor, but I'd have done it in 10. I don't cross thread. I've just gotten things really really tight with no chance of ever getting it back out again.

[@johnkirby4290]

Your video helps. Seeing it done makes it so much easier.

[@wyattoneable]

I never doubted that you'd have the correct tools for the job. 😊

[@mdlee52]

Thanks! lol

[@aidangilmore4944]

You just saved me $500 with this video. Thanks man

[@mdlee52]

Glad to hear it!

[@jacobstrutner8232]

How do you have so much room between the engine and firewall? My deville has 2" maybe.

[@DevaJones03]

This is a Seville that's why

[@snap-off5383]

I think these "hey guys I just did this job, and here's the gist" along with a few videos can be superior to full step by step instructionals for many applications and mechanics with basic skills.

[@alexgaona5682]

Hellpp my downstream 02 sensor connector is damaged 💥 due to the cable hanging under car!! What’ needs to be done??? Help!!

[@mdlee52]

Sounds like you need to replace it.

[@tmroll1236]

thx for the video bud. i 👏 that you got straight down to business instead of rambling on for a few minutes or promoting something like everybody melee that your. constantly skipping parts in the video to find what your looking for. also that you did not cut video while filming. and using language that was simple to understand not just me mechanics

[@pandaxv4503]

Can u help me? How many oxygen sensors are in this engine? Please!

[@JUSTINSTURGILLTRUCKING]

Man I was really looking forward to the review on that cardboard box what that didn’t look as hard As I thought it was going to be and why don’t you want to cross threaded what happened there

[@mdlee52]

I'll leave the empty box reviews to the expert. Oh, and I actually own all of my tools. Remember: A cross-thread is better than no thread.

[@JUSTINSTURGILLTRUCKING]

mdlee52 That is true then cross the roads are better than no threats

[@Leekautorepair]

I think u should make an exception doing how to's. Demonstrating those cool tools u have

[@mdlee52]

I struggled mightily with this basic job, Leek. I don't know if the people will be able to handle watching me mess up simple work.

[@rss608]

Dumb question, when approaching something this I usually use black electrical tape to keep the socket on the extension, how come you didn't try this first? I also tape the extensions together too. I need to replace this on my 96 eldo too. I like the thread chaser Idea....Thanks for the video, will follow your instructions. Someone replaced this sensor in about 02 or so, they broke the evap cover in the process. Spent $1800. to have it replaced. Couldn't figure out at the time how it could have gotten broken until the O2 sensor code started coming up a year or two later..... In tank Fuel check valve is failing, have you tried cutting in from the top to replace the fuel pump module?

[@mdlee52]

That's a good question, actually. I was trying to stack the deck in my favor as much as possible. I did duct tape the socket when I got the locking extension, anyway. I would be skittish about cutting a hole to access the tank... Better just to drop the tank, I think. $1800 would be cost prohibitive for me. Ouch.

[@rss608]

@@mdlee52 I have found that these engines are very fussy, so I bought a AC delco original equip o2 sensor. Problem is that it is to long for the standard 3" sensor socket like you have. Did you break the top of the old one off to get it out? Sorry to bug you about this but I've been working on a solution for this for over a year now. I"ve ordered a 6" sensor socket so I can install the new one, but don't see how you got the old one out unless it wasn't original equip. In the past I had to knock the top of the sensor off and use a standard socket to get them out. Is that what you did?

[@mdlee52]

The socket I have was just long enough to work.

[@kujiko88]

This was extremely helpful, but I don't think I'll have enough time to manage this on my own. Looks like it's either shop time with someone who has the tools, or just not driving the car for a while.

[@BeardedSeabee82]

Jes back ladies and gents! Merry christmas! And good reason to get this vid out there

[@ddl9076]

Thanks for the great job, and kudos to the helper with small hands who reached down into that restricted space.

[@nategotti76ify]

How did you know it was bad? Did you have a code?

[@mdlee52]

Yes.

[@jasonredepenning]

Were you getting a misfire?

[@mdlee52]

No, just a cel.

[@Pureshooter9]

Is this bank 1 sensor 1 or bank 2 sensor 1?

[@mdlee52]

Upstream. Bank 1 sensor 1

[@Pureshooter9]

@@mdlee52 so bank 2 sensor 1 is upfront by the radiator? Upstream also right

[@mdlee52]

What?

[@Pureshooter9]

@@mdlee52 bank 2 sensor 1 is located opposite side of the engine?

[@mdlee52]

I believe it would be. I clarified the video title.

[@pandaxv4503]

Bruh,how many sensors are in this engine? I need for now fast, can u help me how many sensors?

[@mdlee52]

Should be 2. Upstream and downstream. Before the catalyst and after.

[@crazycadillacman]

There are 3 sensors in that car.. 2 upstream and 1 downstream

[@gatekeeperofchaos]

Not bad for a how to video. My son has a friend with an '04 CTS we do work on...hate that Northstar engine. And we have replaced the start on it to😉

[@mdlee52]

Yep, I'm not a fan...

[@HardKnocksForge]

Bah ha ha ha, Empty box reviews on KZbin! Who would have the audacity to do such a thing! I'm going to have to start paying more attention to the tool reviews out there and make sure guys actually have the tool they're trying to sell me in their video. Honestly that nucking futs... empty box reviews??? Come on, really?

[@danmckevittstoolsbagels3258]

Hey, can i borrow that ratchet?

[@mdlee52]

Come on by!

[@jameswhite1319]

Thank you for your time

[@brotherbrian1]

Thanks for the video mdlee52, now change the starter on that beast. 😂😂😂

[@mdlee52]

I've heard that's a total nightmare.

[@brotherbrian1]

@@mdlee52 It's not horrible, it's under the intake manifold in the valley. At least it's a transverse engine. On the Toyota Sequoia it's the same set up but it's the straight engine, which puts the starter bolts about an inch from the firewall. :(

[@michaelm9649]

I have a Northstar. 2004 Caddy. A real shit wagon, kept it for other reasons . 300 grand now . Trying to take out the 02 sensor number 1 upstream . Very limited. Gave it a sprits of PB blaster 2x, I will let it sit overnight. This car has been difficult right after 100k. Very difficult to work because of limited access. What would take you 10 minutes will take you 2 hours

[@jasonredepenning]

I got a buddy that can bend his elbow both ways. Ill have him do it

[@mdlee52]

Well, I guess we don't all have that option. LOL

[@scottpearsontoolsmore185]

Great video thanks brother. The main thing is you got it done and done right. Keep up the great work see you in the next video thanks again brother

[@mdlee52]

That's what I told myself, Scott. At least it was done right in the end.
