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

The Candi module I just leave attached all the time.

@Doubeleive
Excuse my ignorance but what does the Candi module do?
I have the tech 2 and have never used it, it's still in the box it shipped. Bought it last year, lol

It’s needed for vehicles with CANbus systems. Not sure what year that started but if you need it the Tech2 will let you know. If you don’t need it it will act as a pass-thru so no harm to leave it hooked up. I like it because the extra length allows me to operate the Tech2 from the very back of the truck if needed.

Finally replaced the driver side blend door actuator that I’d had sitting for 4 months. 3 years ago it turned hot once, I took it apart and cleaned etc. worked fine until a couple months ago, it did it once. This week it happened 4 times, so in the new one went. Old one still clean this time, the contacts weren’t green and gooey this time under the black gear

I've got one sitting here on my desk to do the passenger side. I'll try without taking the dash off first. If I can't get it, have my daughter try. She owes me anyway, since I put SLP loudmouth exhaust on her Camaro!

Greased that sumbitch!

Noticed some clanky clanks coming from under the front driving it around after sitting for so long while I swap heads 2x. Decided first step was to grease it up. Boot where DS tie rod ends meet was practically empty. No more clanky clank!

It's the little things, fellas!

This might be stupid but.....does anyone know of a cap or something that goes on the water pump center thread when not running a clutch fan.

Swap to an 05 water pump.

I thought they had a cap on them when they're new in the box. Why do you ask?

I have one in stock and checked it out, but still has the thread. i don't think GM would make 2 of the same water pumps and make one with/without threads for a fan clutch.

just wanna cover the threads, it does come with a cap but that is just for shipping purposes so the thread don't get damaged. just slides on top of the threads, and held down when the lid of box is closed.

I was watching a video on youtube from swap guy, he was showing the difference between then L86 And the newer 6.2 that can run on 2 cylinders, and I noticed on the water pump of the 2020 has threads on it where a mechanical fan could screw on to
