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

[j91z28d1]

Make some toe plates like I did.

I have toe plate with camber gauge as well as turn plates. the problem is my garage floor isn't flat. foundation "settling" they call it around tx haha. plus not being on a lift it's almost impossible to reach any of the adjustments without jacking it up, which throws every off. even then I find string easier to get a visual. I was hoping to avoid all that and just pay someone that. keep that for my projects.

You should replace those tee's and the heater hose nipple where it is crimped. They are 3 separate parts and a major PITA. But if one of them let's go on the road that is worst, bad news bears.

Sorry but I got a bit hung up on that third part you mentioned. HVAC Tees you mentioned in multiples so I assume it's best to swap both, there's a 113mm and a 111mm version and i'm confused if I should get one of each or two of a kind. Then connectors were seemingly sold in pairs and that's where my math brain said ****. Trying to avoid ordering a full overseas pallet of different combinations, so what's the reasoning behind the different sized tees and does it matter somehow?

Coolant Hose Change

Aloha Y’all, Does anyone know how to get the remaining cooling hose part off at the firewall? Appreciate any help or suggestions before I screw it up further. Mahalo for your assistance concerning this matter. Aloha! Bill1013 P.S. Any idea the cost?

Picture of how they should be installed. I used a utility knife to cut away some of that firewall matting to make more room to access that tight spot.

Thanks! Gonna try this as a winter project, I've started hearing a weird single loud knock or pop sound during cold starts from the passenger side (note, it only sounds one single time about one and a half minute after ignition). Thought it was coming from the right front wheel since i'm usually making my way from the parking lot by then and just when I'm about to make a turn i feel that one *pop* sound. But this last time it was idling in park when I heard (and sorta felt) it

A/C compressor cycling on?
Or worn balljoint maybe?

Lots of cars have been like this for awhile. Not sure exactly why, but probably to help with the flow. Larger hose on water pump suction side.
Have heard mention of it minimizing gurgling sounds in the core. idk..

Actually haven't had the AC on for a while but it's worn for sure, constant whiny sound when toggled. Since stuff still spins around even when turned off that could actually be it. I suspected the AC clutch but I bet I gotta take the belt off and spin things by hand if i'm making a full day project under the hood anyways. The original comment was about a burnt looking tee-connector and now I'm already adding belts and tensioners to my order. Love it!

I think it's just so they don't put the wrong hose on the wrong pipe. during assembly haha

 

[Doubeleive]

Just the tip, no more flute sound

Have heard that too!

But then, what difference does it make if it's backwards when the hoses are the same size?
It goes through the heater core backwards? Shouldn't matter?
