Finished the install. Should take only 15-20 minutes. You need a 10mm socket and 15mm socket.

 

Remove the plastic guard by removing the 2 15mm bolts from the radiator support. Then remove the 4 10mm bolts from under the engine.

 

Remove the 2 brackets by removing the 4 15mm bolts from the front and rear A-frame crossmembers.

 

Install the rear skid plate using the same 4 15mm bolts in the same position as the brackets.

 

There are 2 holes in the front crossmember just in front of the new rear plate that need tapped with 2 of the new self-tapping bolts. Then install the front plate using these 2 new holes and the 2 existing holes in the radiator support.

 

I'm adding the link to my new imgur.com album, hopefully your can see them. Sorry about the crappy installed pics. Can't get a good shot without the truck being on a lift.

My High Country 4x4 came with the front skid plate, if you can call it that. It is just a plastic shield from the radiator support to the front cross member. I think the brackets listed in your part

Now when did they come out with this and better yet why don't the Z71 trucks come with them from factory? I know several of us have discussed wanting/wishing GM would have put the metal skid plates a

Looks great! Plates nice and thick, looks like aluminum right?

 

Edit: Just looked at page 3 thanks for all the info. Might be grabbing a set!

 

Where does the little black plate go?

Where does the little black plate go?

The black steel plate goes under the transfer case with 4 self tapping bolts.

 

The other 2 plates are aluminum.

 

Check my post back on page 3 for the eBay link to get the kit for $183 shipped.

Wonder if they would fit the HD trucks, anyone know if they use the same skid plates as the half tons?

Thanks a ton DanY for your help and write up on this. Should have mine in a couple of weeks and your install instructions will come in handy. You keeping the transfer case cover or selling it? I will probably end up keeping mine, the one on my truck is made out of steel because it is already rusting so may need the extra one in a few years.

I haven't decided yet. I'll probably keep it for now. Now the 10 leftover self tapping bolts may be another story. I'll keep 4 for the transfer case plate. I paid the dealer over $8 a bolt when I bought my original transfer case plate.

Some idiot dumped his ladder on the highway over the weekend.... I ran over it at 65 mph. Fortunately, it was just a small bump for the truck, but it could have easily been worse. I'm having skid plates installed tomorrow.

Can't get your link to work. Hearing about DanY having to install 2 self tapping bolts has me worried that the 2014 does not have the holes to tap into that the 2015's have. I hope that is not the case!

I didn't have to do anything special to get them to fit. Just unbolted the plastic ones and bolted up the aluminum ones.

Thanks ajdata! So you didn't have to install two new self tapping bolts for one of the front skid plates?

You do have to install the rear 2 self tapping bolts for the front plate. There are 2 holes in the front a-arm cross member. They are sort of punched inward, not a simple drill hole, this gives them some depth for the threads to cut into. From what people here say, they are present on the cross member for the 2014-2016 models.

 

If you want to convince yourself, take 10 minutes and pull off the plastic splash guard. You will see the holes directly in front of where the 2 steel brackets bolt to the front a-arm cross member.

What is a self tapping bolt? When I hear that I think of a bolt with a sharp point designed to penetrate an area that did not already have a hole.

These are GM bolts that are tapered a bit. They use them on a lot of attachments to the frame without having to tap the holes. The tapered tip allows the threads to bite when you start turning it in. These bolts are 10mm x 1.5 thread. You can use regular bolts if you tap the holes with a tap and die set.

 

The GM part number for these bolts is 11518341. They are listed as M10x1.5x25. Retail for 4 is $37.40 with tax.

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

      By Atlas · Posted

      tl; dr I've now reached the 6th floor of hell. I'm chronicling my journey for my morning readers.   Pulling the top of the intake apart was moderately easy but it involved a lot of parts, connections, and minutae. I was preparing for the new fuel lines to arrive ("nut and bolt kit" it's called). The fuel line connections are notched and held in place by the manifold and a metal plate with a T27 screw.   It's on the back of the intake, under the firewall, with little clearance, and two hard metal fuel lines in the way. I was using Franken-tools (weird combinations of 1/4 inch ratchet with/without an extension, with a bit holder for my T27) to get in there. One of my sockets and bits fell off and has yet to emerge on the floor. I lost a second setup and that's when I almost started throwing tools. But that was the point at which I had gotten traction on the Torx head, and it promptly stripped. No more traction.   I started humming "1-877-kars-4-kids" because I was about at that point. You know what? I'm $1500 into this thing and I can make it disappear just as quickly. This isn't fun anymore. I had spent a lot of time already "tidying" around the engine bay: Fixing all the "someone's been here before!" BS. The truck has been exclusively dealer- and shop- serviced and I'm reminded of why I never let other people work on my cars unless absolutely necessary.   Speaking of dealer service. This truck has a 1" stack of records going back to 1995. I put them all in an excel spreadsheet, date/mileage/description.   The CPI spider has been replaced 4 times in 85k miles. The EGR? Another 4. Multiple, multiple O2 sensors. One Cat. 4? Sets of plugs and wires, and I swear half the stack is diagnosis paperwork for "misfire, runs rough, extended crank, dies at stoplights".   GM was producing some proper crap back then. And it was still well within the era of brittle/crappy plastic. (Windows 95 was released the same month this truck was sold new, we HAD the technology!!)   There (was) a plastic shroud around the evaporator core and HVAC fan in the engine bay. I noticed a chunk of it missing so I poked at it some more and it literally shattered. Touched it some more and pieces were crumbling off. Had a good laugh. Clearly whatever plastic garbage they were using had broken down over 30 years and was literally turning to dust. That was a good half hour of using a shop vac to remove the rest of it.   Back to it.   I was going to give up for the evening but then decided I'm already level 10 pissed off at the stripped screw: G* D* it, give me my tools back -- and my JOY. We'll do this the hard way: The whole intake is coming off.   Blazer won Round II. After finally finding and accessing the 12 intake bolts and using a pry bar to unseat it from the heads, it popped loose in an explosion of gunk and grime raining down into open ports. Awesome.   6 times I reminded myself: Be careful of the temperature sender on the front of the intake.   YEAH, I forgot again and snapped it clean off in the removal. Add another $20 to the ever-growing list of new parts this thing is consuming.   The shame is, long before removing the intake, I had changed the oil in prep for Tuesday's momentous fuel line replacement that was going to be the magic fix and I'd have a running Blazer to tool around in this next weekend. The intake removal, including raining gunk, also gushed dirty coolant all over the valley. Of course it did. Welp, there goes another $35.   I now need an intake gasket set, bolt set, coolant temp sensor, another 5 quarts of oil, some RTV. Don't worry, I've already got 3 new jugs of Dexcool and a thermostat waiting. I'll fill it with clean water first to get it running, dump it, and then add the Dex later on in case... well, let's not go there. I'm only tearing this down once, next time the truck is going on Marketplace for FREE.   Oh, and I'm going to need vacuum hose for all the stupid connections placed at the rear of the engine which have since disintegrated. Come on, GM....tell me you don't do that anymore?   Oh, and the ears on the distributor where the cap screws down are both cracked. I mean, why not put a new distributor in it too. You get a distributor, YOU get a distributor, Everyone gets a new distributor!   This truck isn't out of the woods yet...I'm already questioning how much more time I'm willing to sink in.

      Bent valve in 2025 GMC Canyon Denali - Requires engine swap at 14K miles

      By William Aldrich · Posted

      NewDude, thank you for the suggestions!    I did follow up and the dealer indicates he has an open CX case and is working with DPAC (Dealer Parts Assistance Center).   Per the dealer, GM has had a quality spill and is not providing an update for when a replacement engine will be available.

      Poll: Does your truck have the rear window leak?

      By Silver Yeti · Posted

      That's interesting.   There was a factory wire-hole in the back, top of the rear cab, which had a wire for the third brakelight assembly running through it, as well as several holes (10 of them I believe) for all of the studs coming off of the 3rd brakelight assembly itself.   I sealed all of those holes with RTV/silicone as well.   I found it kind of odd, that none of those holes, were sealed with any kind of sealant by the factory - if there was any there, it wasn't very much.   That said, I've been out in heavy rain and have ran the truck through high-pressure car-washes a few times now and she has been 100% water-tight to this point.   I feel very confident in the repair, we'll see how it holds up.

      2024 Silverado 2500 HD with the 6.6 Gas (L8T) Engine

      By Jay-22-2500 · Posted

      I bought a used 2022 2500hd with 6.6L in February. In March took a 2200 mile trip towing our 6500 lb trailer. Changed the oil day before leaving and when we were arriving at our 1st destination, low oil light came on (roughly 1000 miles) it was 2 qts low. Now it towed like a dream, no issue there, and we did go through the mountains of TN, but still, 2 qts! Luckily I did purchase an extended warranty. Brought it to the dealership in April, oil change and consumption test. Brought it back last week, 1300 miles, no towing, and no oil showing on the dipstick. GM is reccomending a new engine (cheaper than them rebuilding), we'll see if the warranty company comes through.
