The reason I ask is because the design of the cab may be contributing to all the water leaks we are seeing. I just can't see under the spoiler on my truck to tell.

Not sure what GM engineering was thinking on this design. Build a dam and theoretically it should not leak, but even the HOOVER DAM leaks. The engineer that designed this should be stripped of his degree and made to wash windows at GM CORPORATE offices. As for GM they are sitting there with potential for a lot of expensive repair cost, as these vehicle get older.

David, did you need to drop the whole headliner or just the rear area?

Just the rear area, I took off plastic rear panels (that house seat belt), hanger hooks above rear windows and side panels that house front belts. You can then gentle and carefully pull far rear End of headliner away from rear window trim.

 

oh and also pull rear overhead light, pulls straight down with 2 clips.

Thanks for the reply. Not exactly how I pictured it under there but, it does look like the water goes right down on top of the seam sealer. No lip above the window to keep the rain from directly running to that arealike the older gen had.

Davidj98, how did you get the yellow clips that hold the spoiler on to release? I can’t seem to figure out how to get something on them to squeeze them enough to release the spoiler.

Just helped a friend pull his today, I ended up shaking and pulling, if feels like you going to break them but they will release. There are only two yellow plastic clips.  Metal is also thin where they connect, the hole was a bit deformed, so we used a smaller hammer to make metal flat again around the hole were clip connects. I don’t think there is access to those clips from cab. 
 

Also make sure small black washer is is still around clip before reinstall, they fall off easily.

Thanks! I was so worried about breaking those clips that I was afraid to pull on the spoiler too much. After reading your response, I went out this morning and was able to remove the spoiler and install my new 3rd brake light. I appreciate the info!

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Progress... sort of.   Intake is disassembled, spider is out, fuel lines removed. Used a torch on the stripped screw with the lower intake off, much easier when I've got the intake sitting on my workbench, I made it talk. Walked right out with a pair of vice grips once it was nice and toasty hot.   New parts are piling up on my service cart waiting to be installed. Distributor, temperature sensor, new gaskets, fuel line kit, themostat, water neck.   My new pickle is I don't want to spend $600 on a replacement spider. I'm not sure IT is bad. I'm probably splitting hairs. Or it's $300 to send mine away and another 3 weeks of the truck just sitting. I have half a mind to assemble everything with the old spider to see if I can get away with just replacing the fuel pressure regulator to be safe. The obvious issue was the gushing high pressure fuel line which will be replaced. Getting to the spider really isn't that hard, and now I know what I'm doing , swapping it would be a breeze should it absolutely need one. Stupid, or smart?   The part that gives me pause is replacing the distributor. Well, it's already out. And I didn't mark it, whoopsie! Engine was at TDC when I removed it, I know that, so upon correct reinstall the metal tip on the rotor should point to the TDC mark on the distributor because that's where it was pointing on the old distributor. Worst case I'm a tooth off and have to re-stab it.   But then, what? I assume the truck will start. It doesn't appear the timing can be set. Here's the problem: These distributors can't be rotated but a degree or two, by design. What I read is Cam ****** needs to be -2 to +2 degrees, ideally at 0 (and checked/set above 1000 rpm). There should be enough wiggle to get that properly set, but checking the reported value is another potential issue. My Actron 9185 scanner says it supports enhanced GM PIDs and Cam ****** is one of them but it's unclear that I'll be able to correctly see it over OBD 1.5. I can see why people end up junking these things with life left in them. They're an absolute nightmare with tweener-year diagnostics/electronics and unobtanium parts.   Fingers crossed it starts and idles nicely. There can be hope, right? I'ma buy a lottery ticket the same day just in case.   Next steps..DO IT. I have not installed an intake before so I've been reading and watching a lot. Some say NO RTV except on china walls, some say DO RTV on water ports but not fuel/air intake. 1/4 or 3/8 bead on China walls? I think my strategy will be, obviously, RTV china walls with overlap on the gasket corners. Chapstick-style RTV the water ports. Leave intake ports dry. The only set of intake gaskets I could find locally are Edelbrock performance gaskets (uh...for an asthmatic 190hp V6? LOL) so we'll see how they do.   #NoToolLeftBehind. It took an hour, but my recovery mission for my deep 10mm socket was successful. It had rolled down the bellhousing and wedged itself between what I think are the fuel lines? I couldn't see it at all, but with a junk antenna I had laying around, I blindly went poking/sweeping for it, heard it clink, raised the truck, and caught a sliver glimpse of chrome with a flashlight way up there in Narnia. I had pushed it farther along the lines holding it captive, but within access of severely improvised tools, poking and cursing at it to finally knock it free to where I could get a fingertip on it to bring it home.    Not much to see.

      2027 GMC Sierra: Official Discussion

      By KARNUT · Posted

      It wouldn’t have happened if the government hadn’t mandated outrageous fuel mileage standards. It does very little for the consumer. It adds cost. Back during Covid there was a chip shortage. They gave a rebate for your truck if it didn’t have the chip to turn on cylinder deactivation. It was 50$ because at best you may see 1/2 a mile increase per gallon. Splitting hairs each fuel mileage trick wasn’t mandated. The government doesn’t do the engineering work and say use this until it’s already in use and they like it. The fuel mileage was mandated. And those add ons the results. There’s a mandate and they are the results.

      It was never mandated.  Ever.    Automakers were incentivized to install it by getting CAFE credits to help with their vehicle fleet fuel economy scores.  They were being handed money/CAFE credits to install it.  Which is NOT a mandate.       The current admin removed the incentives that were behind them installing it.
