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

[willinnashville]

Hey, I get to participate today!

After I lowered my Denali a couple weeks ago I took it to a custom shop close to me for an alignment. First time they told me it was ready, it was so twitchy and pulled left that I only got about a quarter mile down the street before I brought it back. The next day they called and said it was ready again. It didn't feel right but it was at least drivable. I didn't really want that shop touching my truck anymore so I started calling around local but no one wanted to touch it since it was lowered. I inquired about alignment shops on a local Facebook group for lowered full sizes and found a dude on the north side of Nashville (I'm on the south end). Took it over to him today and he did a great job. It was worth the drive home through rush hour traffic downtown to get it steering and tracking right. I'm pretty stoked about that one.

Damn Amazon sent the ac idler pulley. Not the one I need.

Messed up my weekend now.

I was about to ask why, with all the other oddball solutions companies have created for the common failures, someone hasn't made a relocation kit. Looked it up before posting- they have.

Who offers it? Would you mind sharing the link?

I saw a few, but here's an example from ebay. That was the best I saw as others looked to have some extra connections that could be avoided with the specific adapters the Evil Energy one has. They all seem to be $109-$129. If it were me, I'd probably just buy the $15 hose and the two $20 adapter fittings to screw together myself and save half the cost.

Tried driving the Hoe last night. I had replaced the serpentine belt maybe a week ago. I bought the same belt that was on there, which was a little bigger then stock because the original size didn't fit, due to me getting a larger output alternator. The original sized belt wouldn't go on, it was too small after the new alternator. I'd, maybe the pulley was a different size. While driving it I got the "Hot Coolant Temp". Would a wrong sized belt cause it to overheat? Maybe due to the belt slipping? The belt also squealed a few times while accelerating--which its never done before? I was thinking of getting the original sized belt to see if it would fit this time.

Maybe check and verify the belt routing. Maybe water pump is rotating in reverse.

Did the rear brakes pads and new rotors.
Truck look like it still had the original rotors on it after 300k miles. Still had GM stamping on them.

Hit 260k this weekend.

The correct tensioner finally came today. Got motivated enough to put my pants on and swapped it out on the Hoe. Took it for a ride and it's gtg! So that's what the issue was, damn tensioner.
New

Old

There definitely was A LOT of excessive play in it. New one is tight as a drum.

Refreshed the headlights and turns signals. They weren't terrible to begin with but they looks so much better now. It really makes a difference in how old the truck looks when they are cleaned up.

Ok, I finally installed my electric fans. Followed instructions to the letter. The fans aren't kicking on. It actually overheated while running. Stuck the correct wiring/color into the corrects pins, into the pcm. Everything else was pretty much self explanatory. Should any of the plugs going to the fan be hot at anytime? I even tested the plug that the 2 fan leads terminate to. I bolted the constant 12v to a hot pole in the fuse box, and I have a good ground--I tested it to make sure. What am I missing here? @ScottyBoy ? Anyone??

 

[Tonyrodz]

What's a good way to test the fans now that they're installed?

Ground either blue or green wire or disconnect the connector where the wires to the pcm are junctioned and use a test lead to ground either side headed to the harness/relays. One is low speed, the other high.

I'll give it a shot. Thanks @mattbta.

What brand did you have before? Just curious so other members don't buy it.

Did you get the pcm program for the fans to kick on?

 

[Tonyrodz]

The pcm was supposedly tuned for it. I'm gonna call them Monday and see what they say, even if I have to bring the pcm down to them so they can bench tune it.

FIXED!!
It was instructional error. I had the constant 12v bolted on a constant hot pole under the plastic fuse panel. I moved it to the constant 12v "red box" next to the alternator. Fans work as they should.
Thanks to everyone who chimed in.

Constant hot is constant hot. It should've worked. Unless, that constant hot wasn't actually a constant hot, like if it was for a trailer brake or the power for an RV plug. Which, I think it'd need the fuse installed to actually make it hot. I think my fuse & relay center has two terminals next to each other- one is always hot, like the main power coming in and the one next to it is the auxiliary.
