Have the 2020 Silverado Custom. The truck came without an insulator pad under the hood.

I haven't been able to find a correct part number for the custom.

84391123 is the option for the trim packages RST, LT, Trail Boss.

84391124 is the option for High Country and LTZ.

When trying to order, neither one comes back as a fit for the custom. Not sure if I even need one or not but they are inexpensive and heard they reduce heat. Any thoughts on this?

It looks like 84391123 is spec’d for the 5.3 and 84391124 is for the 6.2. As soon as I enter the 4.3 or 2.7 as my engine in the browser the insulator option goes away. Even an RST with the 2.7 won’t show the part. I looked under my hood (4.3 Custom) and it looks like the hood is punched correctly to accept the retainers. I used to gmpartsdirect to investigate the part numbers. 354eef48541ad4615679ca4bec7ac23d.jpg

I think they are all the same, there are no different part numbers. I have a WT 5.3 and it fit no problem

I always thought it was a safety thing where it acts as a fire blanket incase the engine catches on fire the plastic screws would melt and the blanket would fall and smother any flames. If that's one of it's intended purposes I'm actually surprised every vehicle doesn't have one?

That’s what I thought too so I was surprised mine didn’t have it. I have the custom 2.7l. Did the WT trim not come with it? I was thinking it was more engine related... maybe the to let the 2.7 cool more and obviously noise would t be as much of an issue with that engine.

I was wondering if there is a logical reason my 2021 Sierra 1500 does not have a hood insulation pad but the Silverados do? I do note that the firewall now has an aluminized pad that my previous Sierra didn't. Would it hurt anything to order a Silverado pad and put it on my Sierra? They are relatively inexpensive and I assume add a bit of protection/longevity to the exterior hood paint but wouldn't want to overheat anything or cause any other problems.

Thanks in advance for any advice on this matter.

      Needing this part.

      Still looks like a rivet to me in the pics, I don't see a nut and none of the pics show the head of the screw. But if you says so.....

      Tire psi

      By jgaudet99 · Posted

      Thanks for all the help so far!   I did try right from 2026 right down to 2021, and only from 2023 down lets me select the option for tire psi change, but I get the vehicle not supported error!   I'll definitely try it under Chevrolet after work today, and I'll get the sensor number from gm for my truck tire sensors. And I'll let you know if it works for me under Chevrolet!   And if that doesn't work, I'm going to guess that what @Atlas said about maybe I have a different body control module could be true!

      2010 Avalanche 5.3 not running correctly after engine swap.

      By Jsdirt · Posted

      From where I'm sitting this sounds like a compatibility problem. I'm assuming the 2007 was a 900-series truck, and not an 800-series (they were sold side-by-side in dealerships that model year), since it starts and runs.   This is why I HATE post-2006 vehicles. Everything becomes a huge problem when you try to keep the thing running for longer than the manufacturer has designed it to.    I can't remember when Global-A architecture started - either '10 or '11. For your sake, you had better hope it's '11, or you're going to be spending some BIG money to correct this cluster-eff. That's something you need to find out before doing anything else. You may have several computers bricked ... but the fact that it runs tells me you MIGHT be ok here.     EDIT: Just did a quick refresher. You're screwed. This is Global-A. The 2 systems are NOT compatible in the slightest. Once you get the correct engine in there that IS compatible, you're going to need to see how many computers are locked. Absolute NIGHTMARE to straighten out, too. Your buddy might be better off cutting his losses and finding something else.   Welcome to post-2006 vehicle electronics. This is why I quit the industry, and drive nothing built after 1994. This stuff takes all the fun out of wrenching!

      True, hard to say what differences there may or may not be between Chev and GM as well as a production year or mid year part change either.    I just found it odd that under the Sierra choice on the Autel that many of the last few years of production year did not include the choice of changing the tire pressure but if that is an Autel thing or a GM thing as to why the choices were not there. Knowing what tpms sensors are on the truck should give some guidance into which choices on the tool even make sense to try as I wouldn't give up just yet with the tool but I guess he will see what if anything he comes up with if he finds out a bit more info and tries a few more things on the Autel.
