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

[Charlie207]

Eff that. I’ve done that a few times, they always look even worse within a month.

There's UV sealant you need to apply.

 

[j91z28d1]

there's a k2 clear coat made just for lights. 2k is clear with hardener, but instead of mixing it and then needing a paint gun. it's in a spray can, just break the bladder inside, they mix and you get proper 2 part clear from a simple spray paint can.

tape around the light, wet sand with 600-800, clean well with glass cleaner, let dry and hit it with 2 coats of that clear. be as good as oem new, which is better than most aftermarket housings.

tons of good youtube videos on it.

I used complete “everything is included” kits each time. Waste of time and money.

Just discovered a hi-flow power-steering leak.... like all of it within a day. So I ordered up those three hoses and seals. The cooler looks dry & fine at the core and hardlines, but at the pump and rack there is so much muck and wet schmutz that I'm really not sure where the leak is... so they're all getting replaced.

I used to restore headlights when I had my business. I had 2 4oz bottles that I'd mix together--it was the UV protector. That stuff was amazing--but at $45 a bottle--expensive AF.

I did the same thing on my '07 a couple years ago. All new pressure and return lines, plus a new steering rack because my original was leaking. Gotta watch those line fitting seals on the rack. Easy to get them in there cattywompus such that they leak.

noticed my power steering not doing so great again when parking, must be the warmer weather.. Have new pump & lines if needed, but i know my steering rack bushing loose.. clicks on right side when it moves.

usually the seal inside the hydraulic cylinder gives out, so each time you turn the wheel out the fluid squirts out with it.

I'll see if I can get a helper to turn the wheel while I'm looking closely at the rack... w/safety squints engaged.

To be honest, there was always some sort of seep/small leak, but I never took it seriously. There was always something else more important leaking. It passed inspection last Oct. with no issues, and they never mentioned anything. So... who knows.

That's exactly how my steering rack failed.

@Doubeleive

When you say "squirts out" do you mean at the connection point for the high-pressure hose, or out the ends of the rack?

if the seal is bad it will come out right where the steering rod comes out of the rack under/behind the bellows, so when you turn the wheel out fluid comes out
the bellows does not hold any pressure it just helps keep dust & dirt out

In my case, I had a significant leak at the drivers side steering rack bellows because one of the internal seals in the rack was failing. I also had a smaller seep where the pressure line entered the rack.

Finally changed all the evap parts charcoal canister, purge valve etc

 

[tuckerrnr1]

You should notice a big difference now when filling with fuel.

Did your purge valve kit come with instructions and hoses to relocate the purge valve to up by the filler neck from down by the frame?
The kit I purchased when I changed out the purge valve on my sister's 2008 Silverado did.
Purge valve was stuck closed and it would take fuel at a trickle.

FWIW you're thinking of the VENT valve. The purge valve is in the engine compartment.

thought that's where they were always supposed to be? when I changed mine it was dangling down by the frame because the zip tie that was holding up on the fill tube had broke, when I did any of my gmt800's they were attached to the fill tube.
that's why I tell people to just disconnect the fill tube and pull it down to change it out, then shove it back up there and re-attach it. Otherwise your going to be struggling to do it in a crammed up spot, disconecting the fill tube is super easy

Hers was down on the frame held on by a nice stamped, metal bracket.
Maybe it is just certain models that have that vent down on the frame or maybe GM decided having it mounted low was an issue so they moved it up as a running change during production?

I tried cleaning ( with the good stuff)... a Honda Civic ...stock headlights had a factory film. Couldn't polish the plastic.
