What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[Rocket Man]

Funny, I just went through all my maintenance records for the Yukon and couldn’t find I ever bought new O2 sensors and no service invoices showing even one was replaced.

So I decided I would order 4 Delco OEM sensors from RA and replace them all. When I went on their site, they label both part numbers they sell for my model year as Downstream.

Did you run into that when you got yours? I suspect Denso makes them for Delco, might just get those.

Look at the connectors, upstream are different than downstream.

Good tip. I also went to the Denso listing and cross referenced the OEpart numbers. Interesting in that Denso has a 30 day warranty and OE 2 years unlimited miles. OE obviously a little more, but all still way cheaper that my local NAPA, like half.

Make sure to check the ABS connections that are located on the frame rail right below the top mounting bolt. With them behind the bracket and hard to see, people have a tendency to disconnect them unintentionally with the wrench then wonder why they're getting lights and error messages on the dash when done.

I didn't have a problem with them though. I was aware of them and was careful and watched what I was doing

Double check your ABS connections on top of your frame rails when your done.

Did that about hour ago, thanks! Along with a new air filter, I am too embarrassed to say how long it has been since I changed it and what condition it was in when I checked last night. I guess there is a reason my dealer is so cost effective. I gotta quit my "on autopilot" approach to maintaining this thing.

Then theres this.

Did you replace all the tubing, or just the one short one?

I just replaced the one short one on the driver side. Yes, thats the heat shield.

I got my tubing kit yesterday, I take it you did too? I plan on replacing them as a maintenance item so I’m in no hurry but don’t want to stash the parts away or I might forget.

I did and I am glad!

We had an unexpected nice weather day today. So while my neighbors were doing yard work I installed my catch can. I split the existing plastic PCV hose and used a heat gun to mash flares into the ends (I'd bought a replacement just in case). I also put a 90 degree twist in the long piece so it would point in the right direction. I mounted the can on the hood spring bracket, and ran 3/8" fuel hose to the PCV hose in back. The mounting bracket it came with was kinda sketchy. So I made a simple spacer to allow bolting it on without the bracket. Aside from the worm drive clamps, it almost looks OEM. Everywhere I tried for the spring clamps was out. So I'll get some later and swap them over. Don't mind the dirty engine compartment. The weather has been crap for the last month.

Nice work.

Replaced the broken exterior handle on the front passenger side door.

Replaced the speaker on that door while I had the panel off. I had replaced the drivers side last year.

Changed the oil and had the pleasure of having my 13 yr old daughter help me with the oil change. Pretty cool to get do that with her.
