Anyone have instructions/links/pics/info on how to adjust/install a GM factory tonneau cover? (came with the truck (09) already installed and no instructions)

 

I had to take mine off today to fit the atv in(to get the tailgate closed) and I seen some adjusting tabs/slides that look like it can be tightened or loosened?

I also almost lost 2 of the end caps on the rails as they were not tight at all.

 

Thanks :D

Did you take the side rails off?

 

No, I never touched those, just the cover was removed.

At the front on both sides were some type of holders that had a bolt and a nut(jam nut?) attached, it went through some type of slide and I could tell you either tighten them or loosen them.

I guess I could do a trial and error thing but it would be nice to know what I am doing first.

I have always thought that mine could be tighter, seems to bow down quite a bit while driving.

If it's that same one that I have, the front snaps into place sort of like the rear and has the little pull string to release it. Those corner pieces finish off the corners to keep stuff out and they should have a set screw in them so you can tighten them down to the side rail. Put the corner piece on and then tighten it. Take the back rail and put the passenger side in first, then pull the string and pop the driver’s side in.

Thanks, I got that figured out when I took it off and reinstalled it, I was just lookign for instructions on how to adjust the tightness etc.

I remember reading a post a month or 2 ago, in it the guy said it was adjustable ie: tightness but no info on how to do it was shared.

The 2 slides in the front corners of mine are not tight, they just hold it in place right now, barely! Looks like this tonneau was just thrown on without much care about taugtness, straigthness etc, that is why I am looking for installation instructions/pics, hopefully they cover how to install and tighten one properly? :thumbs:

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

      By Atlas · Posted

      My office is slowly filling with Blazer parts. Getting ready to do the big bang of repairs. Intake (second time), water pump, radiator, hoses, and I'm going to re-seal the timing cover where someone went hog wild with silicone. Might as well, because I don't think that's done right.   There's a local tow yard that I didn't realize also has quite the inventory of junk vehicles. This is an old school junkyard. No waivers. Cash only, you were never here if anyone asks. Don't piss off the owner, or you'll end up in the back of one of those cars, headed for the shredder. And if you see something, don't snitch. Cars stacked double high, wasps nests, trip hazards and junk everywhere. I found a few little odds/ends for my Blazer. The $20 I spent was worth the experience alone. But I was never there. What yard?   I officially love/hate this truck. It's so out of my wheelhouse, roughest vehicle I've ever owned. Every. single. repair. -is so hard-fought, everything that can go wrong, goes wrong. Currently in a hate phase, and kind of wish I was closer to sending it down the road with a lucky new owner, to be honest. Preparing for the day when I tear into this thing...lots of pre-funk with Ibuprofen.   Rock Auto sent me a bad reman rear wiper motor. It was a bear to install. The tailgate in these things has about eleventy-billion fastners and pieces and things that need to be uninstalled/moved just to access the shoddy rear wiper motor. The casing on mine was cracked clean through, btw. Nice, GM, nice. SO I got this new motor installed, hit the switch, I see it wig-wag (without the arm installed) and think I'm golden. Reassemble everything. With the wiper arm installed I gave it one final test. Time to clean up and take the other half out to dinner, collect a paycheck, right?   Nope. I hear the plastic worm gear stripping as the arm hung up. Just like my broken motor. Weak/old and shredding itself internally. I can assist the arm and the range of motion is normal, and it parks correctly. It just doesn't have the poop to actually sweep the arm with a blade on it. Oh, hell. Turned the key off and shut the shop door behind me. I get to do that over again, too.

      AFM Disabler Question

      By BlueV8 · Posted

      A complete delete is the most thorough mechanical solution, but it is also major engine work. On a quiet truck that is still under extended warranty, opening the engine purely as prevention is difficult to justify. A plug-in disabler stops commanded cylinder deactivation, but it does not remove or repair the collapsible lifters, so it should not be treated as failure insurance. I would keep the oil full, document the maintenance, and have any persistent tick, misfire, or loss of power diagnosed promptly. If the engine eventually has to come apart, that is the logical time to compare an OEM-style repair with a complete delete. The right choice depends on the truck’s symptoms, warranty status, expected ownership period, and whether the engine already needs to be opened. We explain that decision in more detail here—full disclosure, this is our own guide: https://www.bluev8.com/blogs/news/do-you-actually-need-an-afm-disabler   One exception: some 2021 L82/L84 trucks have RPO YK9, meaning cylinder deactivation was already disabled in the factory ECM; on those trucks a plug-in disabler is redundant, although the AFM/DFM hardware remains inside the engine.

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?

      I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery.

      The lifter issue can be dealt with by shorter oil changes and quality oil IMO.
