What did you do to your NBS GMT800 Tahoe/Yukon Today?

[Sam Harris]

Source for OEM Knock sensors and harness..? I've been looking around, and strangely, there seem to be more than one option. I found the sensors on Summit, $65 each: 12589867, and they don't seem to have the OEM harness...?

I also ordered a Gates water pump, p/n: 45006, as I had this in my Amazon cart as a -just in case / down the road item.. Now that I'm looking up part numbers, I want the OEM ACDelco pump.. And looking on Summit, I see Delco: 12703898, and 19195104. Both say they fit, and they look a little different.. wth..

I'll go look on Rock Auto. Hopefully that helps.

ETA: Looks like the 12703898 is the GM OE part, and does not include the thermostat. I'll get this one... On that note.. any reason to go with a t-stat cooler than stock..?

@Rocket Man @iamdub, do I really need cooler plugs, or were you just reacting to my quip about throwing an LSA up top...? I'd love to do that, but damn, even this "little" experiment is really piling on the cost with the nickel and diming of all the "supporting mods" and "while we're in there"..

Oh, and my 2nd vehicle I use to save a few bucks on fuel, since I'm now driving 670 miles a week, just to shuttle the kiddo back and forth to school... Oh, she gave up the head gasket 2 days ago. So I have to either swap the motor, or do the head gasket before I can think about getting the truck in the shop for the fun stuff. Not that 99% of it is here yet... lol

I didn’t say anything about cooler plugs. I don’t think you’ll need them but @iamdub is more experienced than me so maybe he’ll chime in. Sorry about your daily’s head gasket. But replacing that shouldn’t be too hard from what I hear although I’ve never done one. Sorry I’m not much help Sam.

That sux.
Pretty sure @iamdub was the guy talking about the coolant "bypass ". I'm not sure if that's the correct term he used describing them. He's still on the hunt for another tube tho.

No worries.. Really thinking I should just motor swap, since I already know the bottom end needs help (rings on cyl 1).

I discovered the voltage that the fob batteries quit working- 1.7, down from the 3.3 they start at. Seems like I replaced it not too long ago but now that I think about it, it might have been a used one. Back up and running with a new Energizer.

Sorry @Sam Harris , I was thinking of something totally different lol. I thought you meant those coolant passage tubes that @iamdub has been on the lookout for.

Programmed new Boost Auto fob. Should have kept the one I had for my Tahoe when I sold it. Glad PO installed a remote start that uses triple lock press on OEM remote to start. New fob works like Great.

I admit, I was thoroughly confused... But considering all that's on my mind right now, I figured I was just missing it.. Lol

Sorry buddy, I don't want to add to the confusion.

@Sam Harris I couldn't find oem for the harness, so I just sent it with whatever decent reviewed one I could find. Oem sensors, tho.
