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

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

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

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.

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

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

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

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

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.

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

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.

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

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

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

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

Thank you for your time

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😉

Thanks for the video.

Thanks for a good video

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

Thanks for the video

Thank you for your video .

Good video Mdlee52

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

It help me out thank you 👊

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

1st BOOM

Bah ha ha ha, Empty box reviews on RU-vid! 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?

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?

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

Were you getting a misfire?

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

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

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

Hey, can i borrow that ratchet?

I need to poop
