@Jebus Hypocristos shoulda got the zr2. or dodge..chev allways cut corners.. historically.. polished sht is still sht..buy something pre 95ish. cheaper, stonger, better..
I worked at the plant that made frames for GM as an maintenance electrician . Saw the entire process from start to finish. The frames are dipped in a tank of wax in the last stage before shipping. We shipped 22,000 frames a week. When stacked on the rail cars for shipping the frames already had rust spots at any point there was a small scratch or thin coating. Because it is dipped and on a hanging conveyor system the hot wax would run from the top to bottom and drip off. You can see the drips when looking at the back of the frame. The wax would be thinner at the front because it would run to the back as its hanging. They claimed it was self healing if stone chips damage it. Ahhhh NO.
Lmao I’ve heard of paint being able to heal it’s self when exposed to uv but a wax I think not gravity is still an issue. Not to sure why they don’t dip it from the front instead of the back seeing how the material motion of the vehicle is to move forward obviously having to deal with more elements at the front vs the rear. Guess the common sense wasn’t there.
My bosses friend brought his brand new Chevy truck over to show off. I looked under the frame and wiped off a bunch of rust around the Trans crossmember. Nice summer day, right off the lot! This winter I saw a 14 with rust bubbles in the fenders. In 2019 or 20 I saw a 2010 with rust holes in the bed fenders. If the 2014 sat on the lot 3 years, that makes the truck 5 years old with rust holes! Why would you buy a new Chevy? My 99 Tacoma looks like crap but it's been in a salt bath for 23 years. These Chevys won't be here's in 10 or 15 years. Where's the ROI on a 7 year old rust bucket that's still got payments? It's a financial trap in my opinion.
Ford did this for a long time as well, particularly in the early 2000s. I never understood waxing a frame. It's going to scrape off over time and then the frame doesn't have any protection at all.
Oh and one more thing - Thank you TFL and André for this type of video! In my opinion looking underneath a vehicle is much more interesting than looking at how shiny and new it is. How it's built and what's underneath is what matters more, and a mechanic's view will always prioritize different things than what the average consumer prioritizes.
I really love this video Andre PLEASE do more of these! I want to see all the new vehicles in this POV where a lot of us simple folks don’t get the opportunity to see the nitty gritty before making a decision to purchase a new vehicle! Thank you keep up the great work!
It last8 years and 135k on my 2011sierra until I sold it. You can touch up bare spots once and a while with any lanolin base undercoat, which is what that waxy greasy coating is.
Thank you for finally bringing this to the attention of the consumer. You cannot maintain this coating. As soon as it dries and cracks or chips form, rust then forms underneath the coating. You can't area sand and repaint like with an e-coated or painted frame because with paint you can tell exactly where is and isnt properly bonded/attached to whatever surface is painted through bubbling or flaking of the paint. Paint also resists that slow penetration of rust from underneath due to superior bonding to the surface. It is surely planned obsolescence with this in mind and the change to fully boxed frames. The actual material thickness is diminished from the start, then load bearing areas break much faster due to being so thin from the corrosion. You will not see trucks with waxed and fully boxed frames lasting and working hard for 30-50 years like you could previously with open channel frames or with current e-coated and properly maintained boxed frames.
Owning at least 12 Gm cars trucks. To still having 5 Gm trucks we run for business and personal . I've had no problems with motors , very mim trans issues only on the 4l60E, all my 6 , 8 speed trucks no problem down to rust nore paint issues. If you want a truck to last over 250k and up miles with out braking the bank. I strongly recommend Gm. Y'all can believe theses byest videos. Or real life ownership and work horse facts and statements. FYI this same so call truck review channel just did a video on the 2021,22 F 150 truck on how they had to correct Fords frame factory rust issues. When dealing with Ford trucks. This the same reason why I and people who own these trucks give motor trend, car and driver ECT real car long running review companies good consumer reports and ratings. Couse at least they aren't byest and call a spade a spade.
One winter in Wisconsin and those frames turn orange with rust. Any company that does this needs to be called out and taken to court for selling an inferior product.
One of the reasons I went for the Colorado over Silverado was the frame coating, Colorado is e-coated, and Silverado is waxed. That wax is crap and rusts
Love Toby, he’s a crusty 70 year old Mechanic trapped in a strapping young man’s body, he about stroked out at 65k, don’t take him in a F150 Platinum it would kill him when you told him the price and I 100% agree with Toby!!! Great show Andre!!!👏🏻👏🏻👏🏻
@@erikturner8687 you know this "base" zr2 comes fully loaded like the Tundra TRD pro. So what starts at 67k ends at 67k. The only other package is a headsup display which I would never get.
@@JattAnmoli that’s false but ok. Fully option ZR2 goes for 75k. fully option Raptor goes for 82k-86k depending on if you want the 37 package and blue seats. So that’s still only 10k. Not the 20-40k you guys somehow came up with.
I finished coating the entire undercarriage, interior, exterior rocker panels door bottoms with Fluid Film. The Frame on my 2022 truck has the same thick black coating both inside & out. It's a tedious job to coat all the vulnerable areas, but well worth the time if you live where I do. There is salt on the road nearly 1/2 the year. If you keep your vehicles for a long time & or live in the rustbelt you can't skip a treatment. It can be applied with a spray kit or a brush. I highly recommend it.
Completely agree. Sold my 1990 Dodge W150 2 yrs ago. Only drove it in winter, Maryland, PA, Ohio, heavy salt & magnesium chloride covered roads. I applied Fluid film in August or September every year. Only had one rust hole, (2” diameter”) on heal of RF fender. The hole was there when I bought the truck 7 years prior.
@@hemal8569 I’ll just say in my experience, installing emergency equipment on these trucks, the GM “rust proof” coating get rubbed off by rubber grommets and wire loom….. the Ford while have some rust, have not nearly the same issues.
6:49 "See this extra brace..." I'm actually surprised that the lower control arm brace is bolted in rather than as stamped/cast. I suppose it's meant that way so that if the shock needs to be replaced, you don't have to drop the entire lower control arm to do it. Merely unbolting the brace allows enough room for the shock to be removed.
It's just cost savings. That is the regular Silverado LCA made with two stamped steel pieces welded together with an extra tab welded on for the bracket. The Raptor/TRX use completely unique forged lower control arms.
So happy you guys got a ZR2. I'm hoping to get a 2023, maybe bison with the new diesel depending on output. I look forward to the tests and in depth exploration of this truck.
As a mechanic it is so unfortunate that new vehicles all have so many problems with reliability trying to keep up with emissions and fuel mileage standards. Brand new vehicles with less than 10,000 mi requiring major engine work is becoming normal.
Makes you wonder how much these manufacturers are fleecing us when the mechanic low balls the cost of the vehicle by 20 grand after looking over the mechanical aspects of the vehicle.
Good point. But the manufacturers (GM, Ford, Ram) are simply selling the trucks mentioned for what the market will bear. The ZR2 Silverado appears to be a great off-road platform. But, since it lacks a wide-body, power adder, longer travel and 35 inch tires the price point ($67,000) seems high by around 7 to 8 thousand. Also, that passenger side lower rear shock mount needs a protective skid plate ASAP. Maybe try sourcing one from the aftermarket for a Trail Boss? I know it's not the same shock, but it's worth a try before taking it out on any rough, rock strewn trails. Oh, that smallish tank will ensure plenty of stops to get gas for that thirsty 6.2 V8. Sheesh, 24 gallons...gimme a break GM. Lack of a skid plate for said tank is not a big deal to me. An aftermarket one is probably better anyway.
@@billymc2681 this is true. You likely would be able to at least get a normal Silverado for 5-10k less than MSRP if it wasn't for this market we are in. Really sucks how unobtainable a lot of things are these days.
Even though mechanics know how to work on vehicles, most probably haven't worked in a factory where they are built and would really have no clue how much it costs to build a new car. Not saying the truck isn't expensive but lower volume parts on trucks like these do cost quite a bit extra.
I purchased a 21 trail boss in May of last year, 3 months ago I got a new aftermarket bumper to put on. Behind almost every piece of bumper I removed was rust!! I have lots of pictures
That was great! Do more mechanic walk arounds with new vehicles! There are so many things you just wont know about a vehicle until you get underneath it. Super helpful information. Would love to see the fleet get looked at.
Yea, that coating washes off in the high-pressure bay at your local car wash too, BTW. They you'll find a bunch of rust when Winter's over. My 2019 Silverado's frame has it everywhere I pressure washed. (Only once btw. I thought I was getting the salt off) Now I'm going around with a wire brush, and Fluid Film to recoat everything before it rots out.
Great video and I hope to see Toby make more appearances in the future. It’s a nice truck but interesting learning about it’s shortcomings and seeing them pointed out first hand.
Read the owner's manual and you'll find out it shouldn't if it was treated properly. Treated properly to GM means rinse off the underside of the vehicle at least once per year and apply a new coat of the frame wax. Again, read the owner's manual.
@@therealjohnsmith4811 This may shock you, but I check the air in my tire monthly, and change the oil regularly. There's more but I think you get the point.
@@domin8ss the coating dries out and falls off in places you can't get to. It's an awful engineering fail by GM. Not to mention that crud gets all over you when working on a GM truck. They need to paint their frames like other manufacturers do.
I'd like to see this truck vs a 70k Raptor. I just wonder how they would compare. I would think spending a few thousand more for the Raptor may be a better buy.
the only area i can think the zr2 will outshine the raptor is with the electronic front lockers. Im a chevy guy to the bone, that being said paying 3k more for a raptor is the way i would go. Wish this truck was in the 50k range and i would buy one. :/
@@lespaulplayer1234512 no truck with this capability in the segment is 50k unfortunately. Tremors and rebels reach 70k compared to what this offers and no one has front lockers in the segment
If you have to have a Chevy 4x4, please WAIT UNTIL the Chevy ZR2 Bison Edition comes out with all the AEV (American Expedition Vehicle) add-on parts. The Colorado ZR2 Bison Edition is today the BEST BANG FOR THE BUCK mid-sized off-road truck out there an the full-sized version I think will be just as good! Just make sure you put 37 inch tires on it and it will match and even EXCEED a Ford F150 Raptor for overlanding/boondocking. I do know that BED PAYLOAD will be better by almost 400 lbs (181 kg) so that it a BIG SCORE towards Chevy! The V8 does give Chevy the ICE V8 Enthusiast's Edge but the Raptor has much better driving range and fuel economy with its twin turbo V6 so it will come down to WHO has the better price! V
I worked for Dana Corporation in Reading PA on the C,K and cab chassis lines among others. The GM frames were bare steel frame, washed, dried and dipped in a hot wax tank and allowed to dry hanging vertically with the front of the frame at the highest point. So many factors determined how thick the wax coating was, summer vs winter, drying zone temperatures, wax temperatures, but always the coating was thinner at the front of the frame. Then the heat of the exhaust would also melt the wax coating. I thought they switched to E coat later?
Back in the day, a lot of people would take their new vehicles to a local Michgigan "Ziebart" shop and have the underside undercoated (spray on stuff). It also helped with sound deadening. Wonder if anyone is doing this or thought about it? I gotta 2021 GMC Sierra AT4 (6.2L, ALL options) and there is no rust or issues (Oklahoma truck). Sure it has some decent off-road capability, but it FLIES on the highway (up to 98 mph).
Check FordTechMakuloco/BSG Automotive. There is video of him removing Ziebart because it creates moisture when it begins to wear and then rust. With him and others (South Main Auto Repair) you'll see other recommendations for rust protection. Both are on RUclips.
That frame coating is garbage. They do not last and I don't understand why GM keeps using it. Also the lack of a skid plate under the fuel tank just blows my mind. They used skid plates everywhere else except there? This is why I don't buy GM products. If they are willing to leave things off like a skid plate under a fuel tank what else did they cut corners on that you cant see?
I have a 35 year old car with that same type of wax on the frame and it's still there doing it's job. That is some tenacious stuff. It's typically wax mixed with some other bitumen based ingredients. Only downside is it gets all over my hands when I have to work under the car.
Next time when yall take a drive anywhere look to see how many older trucks are on the road, count and take notes, how many fords? Rams? Chevrolet? Everyone says GM products are boo boo but then You see them all over the road.
I have a similar coating on the frame of my 18 Silverado 1500. It has held up well. 75k on it and no degradation. 0 problems with my pickup. Only required oil changes and regular maintenance. 5.3L delivers excellent fuel economy
My 2018 GM truck frame has far more rust than I’d like to see. At first I thought I would not have it too long since I drove it a lot. But, now that gas prices are so high, I bought an EV and do most of my driving in that, and just use the truck for truck things. It may be with me for longer than I thought. I now am more concerned about rusting.
Good job Chevy! I believe Ford's under carriage rust issues are primarily due to having vehicles sit out in the elements for weeks if not months before chipping and shipping.
GM did the same thing with Silverado/Sierras during the supply shortage. People on the subreddit showed pictures of rusted frames from the dealer because the trucks sat out for months in the elements near the assembly plant waiting for parts.
The coating on my 2019 Colorado was actually really good and held up well the couple years I had it. Northeast winters are harsh. Got my new Silverado Rust Checked and will continue to.
Leaf springs, forgotten skid plates, and GM cost cutting specials. Don’t forget the engine destroying lifter issue that they refuse to fix -> way over priced. The mechanic estimated the value of the truck correctly, but got the price wrong.
All I know is that the frame on my 2007 Silverado that has spent the last 238k+ miles on northern roads with salt all winter is just fine. No significant rust at all. Granted, it's not driven off road,but it is driven and driven and driven.
I know a guy that moved to Guam that had his frame break on his Silverado during a simple right turn with no load or trailer. He wasn't recoating the frame annually like GM says to do in the owner's manual.
Keep an eye on the inner frame in between the gas tank on those I see them crack there in illinois on the second gen silverado I have a 2011 silverado with 220k miles myself and just has surface rust on the frame the bedsides are gone though
Syracuse,NY guy drives a Plymouth Valarie daily all year (winter salted roads) he coats the whole car with transmission fluid. The car has no rust and I mean NO rust.
Please tell me it's the wagon I had one as teenager in the late 80s it was very fun car put 230k on it before frame rotted out great memories in that car
That’s an old farmers trick. Afterwards they would drive it down a dusty road until the undercarriage is completely covered with a layer of dirt. Cheap and extremely effective way to prevent rust from forming.
anyone ever wonder is it's planned out like that? I mean, with all the tech we have now days, we still use salt. I think, the manufacturers have a pay out with the states lol. vehicles rust and have to buy a new one. circle of life.
Here in Maine, the wax coating dries and flakes away revealing how thin the actual frame is , and usually a bunch of rust underneath. Fluid Film will make a HUGE difference at keeping rust at bay.
HATE all the gloss black on the front and rear bumpers🙄. What are auto makers thinking by adding all the gloss black trim when they know it will easily scratch and get damaged??
I work at the Oshawa Gm assembly plant where we assemble the 6.6 duramaxes and 6.6 gas and soon 1500’s… this coating is so annoying I would rub so much of it off to the bare metal in so many spots
Dont understand that wax coating. I have a Tahoe that has the same thing. It seems to attract dirt and grime and just comes off exposing bare metal if you barely touch it. GM could have spent an extra few dollars and painted the frame or better, power coat.
I appreciate the video. It really helped me getting a more up-close look underneath before buying one. I just got a question I hope someone can help with the answer. Is there a skid plate available for the catalytic converters area like the Toyota trucks? I'm in an area where converter theft is high. Thanks in advance.
GM started dipping the frames of the full Size trucks in 1999 when the GMT 800 was introduced. It's a hot wax style coating, not a spray on coating as your Mechanic friend mentions .
I discovered the wax coated frame crap this past weekend. Who at GM thought this was a great idea? It is stick when working on it and comes off when jacking it up.
All the talk about surface rust on axle tubes and frames is laughable to me. Living in Canada and driving pickups for over 40 years I have never had an issue with a rusted out frame or a problem with an axle because of rust. Many of my trucks made it to over 2, 3, or 400,000 before they were sold or retired for good. I can only imagine how much road salt they were exposed to where I lived. Most of my trucks were Fords with the odd GM or Dodge in there starting with models from the 60's all the way to the present where I own a 2015 F350 King Ranch and a 2005 Tacoma that I drive the most out of the two. The Tacoma is dead nuts reliable. It has rust on the frame as you would expect but at almost 300,000 it is still not an issue. I give it a spray with the wash wand in the right places when I wash the truck. Have looked at it where it is most vulnerable and it is no where near rusting through. The 2015 King Ranch is the first truck I ever had undercoated and rust proofed because I plan on keeping it forever. People fretting over surface rust on an axle tube under your truck is really unnecessary.
The issue isn’t the exterior frame coating. That is easy enough to maintain. In the northeast and midwest, it is the salt brine that rots the frames and cross members from the inside out. The key is to get the interior frame members coated. My preference is NHOU and if a brand new vehicle the boss wax and seal is great. Lifetime warranty and touch up internals of frame and body every other year for daily drivers or every year for our plow trucks The back to black and clear coating work great for not new vehicles. Fluid film and woolwax are also good products. But you have to treat the internals otherwise the outside will look good, but can be paper thin
Thanks, Andre for a look at the underside of the ZR2. I was down working in Souther Cal (Ontario) this last week and weekend. I did find a ZR2 on at a dealer nearby. There "Market Price Adjustment" for the ZR2 was $10,000 making it a $80,000 truck. Too much for my budget. Looking forward to more videos on the ZR2. I don't think it's direct competition to the Raptor or the TRX. I want to see how it stacks up to the Ram Rebel, the F150 Tremor, The Tundra TRD Pro and last but not least the Titan Pro-4X. I do realize that on paper some of these trucks are more capable offroad. But real-world testing will show if that is true.
Add to that tax license interest and all the other incidentals dealers tack on and you have a $100000 1/2 ton truck. My coworker was looking at 1/2T about 6 weeks ago. He told me it was $116000!!!!!! HOLY COW.
Amen to that. The new automatics are nice, but a good manual will do the job too. I grew up driving them and took my drivers test on a 62 Ford Farlane with the 3 on the tree manual...in 1982.
It doesn't make sense that the Chevy has such a small fuel tank. The 2017 F-150 I had super crew had a 36 gallon tank so obviously that can fit under there because it had a similar size box.
The 36 gallon tank is part of the towing package. I assume they withhold the larger tanks so that consumers are forced to buy additional add-ons. Just like Ford not putting auto climate controls on anything lower than the Lariat trim. Remember when cars didn’t always come with passenger side mirrors? It’s all about the upsell.
Makes no sense that my 2018 Colorado has an electronically dipped frame while the Silverado is still rocking a coating as the main truck lmfao. I thought with the LAST model of Silverado would address this. Two updates later and we're still seeing this.
Thinking about it today ( it was 20 years ago I worked there) I think they did put them in front first. I recall they hooked them by the "rear mod" as it was called and lifted up on the conveyor . After the dunk they went through the "cooling tunnel" to cool the wax. To be fair I am on my 4th GM truck in 20 years and looking at my 5th. I guess I am a fan. All steel will rust in a few days when exposed. Then put it through snow and salt for a few years pretty tough to do anything to stop it. It sucks but look under any truck they all suffer the same problem.
I have three GMCs and one Chevy truck currently and every one of them have extensive rust on the frames even after treating them with Fluid Film spray every fall. I live in Idaho, so not too severe winter, but they sand the roads. Three of the trucks are 3/4 ton trucks and I have to wonder how much load capacity is reduced by rust on trucks all across the US and Canada. There really should be a class action lawsuit against the big three because of the rust all of them suffer.
Anyone know we're haven't answer of why GM is still sticking to leaf spring in the rear? Other manufacturers have gone away from it and doesn't seem to have hurt their numbers for towing and payload
That exhaust pipe being so close to the transmission should have had a heat plate your going to burn your trans oil overtime and im sure itl affect the transmission as well probably will have to do closer trans fluid servicing than normal
That type of wax coating is "Nox-Rust" made by Daubert Chemical (although GM may have their own even cheaper generic version). I remember this being a PITA back in the '70s and when I bought a new 2010 GMC, I was surprised to find the frame was coated with that cr*p. As anyone who has ever worked on a GM vehicle with this coating on the frame knows, it's a real PITA because it constantly rubs off on anything & everything that touches it, especially in hot weather. And it's an even bigger PITA (more like nearly impossible) to remove all of it from every nook & cranny of a frame; you practically have to dip the frame in solvent to get all of it, but if you don't clean that stuff off, nothing applied over it will ever adhere any better than that stuff (which is to say, poorly).
Have you ever done this before, if not, please keep doing this. I love seeing the engineering beneath. Seems like they should have a Carbon fiber skid plate for the tank to avoid sparks, a skid plated for the rear diff you like discussed and should the tranny have some sort of skid plate or is it just high enough that it doesn't need one? Also, I see you didn't get the rock rails on this. Why doesn't GM do disconnectable sway bars like the rubicon?
I know right trucks should come standard with a 36 gallon tank. I have a 36 gallon on my F150 I’ll never go to the smaller tank when I get a new one imagine if you were towing with a 24 gallon tank Jesus
I've got a relative with a 10 year old (130k mile) gm pickup and the rear quarters are already pretty much gone. The thing is a rust bucket. This is in the midwest salt belt.
I drive a 7 year old gmc sierra with 128 k on it in Buffalo ny. Road salt is spread out every time it snows. The frame has surface rust but the body is perfect. If you take care of your truck it will take care of you.
Owned several GM trucks, never had a problem with the coating on the frame. I had an '85 3/4 ton Chevy, best truck I ever owned, probably better than any new truck today.
Y’all are seriously trying to take jabs at GM’s new trucks and their reliability when the 2022 Toyota Tundra is experiencing rear axles popping off mid-drive? I just think that’s hilarious. Truth is, every truck in this segment has had some type of issue or 2 - some more serious than others. This video is about GM mitigating issues like rust from happening though. Just funny the comments are talking about the skepticism of a brand new _2023 Silverado_ barely reaching 5k miles before experiencing unprecedented and catastrophic *failure* even though we’ve witnessed this already with a brand new truck it just wasn’t a Chevrolet.
In NH the silverado is rusted in a couple years. The undercoating needs to be done every year or every other. The new PB blaster undercoating is legit. I use that, Fluid film or NH oil undercoating
add yourself a heat shield over the exhaust flattened tube between the trans pan and the exhaust. airflow at speed will work to cool, but off road, why in the world would you not keep the tranny fluid pan from absorbing all the exhaust heat in that location.
That all looked pretty nice to me. But damn that price tag....idk for that I'd want a diesel. Price aside, looked like a fun solid truck. It's remarkably similar to past generation Silverados. Starting in 2007 they went to a "fully boxed" frame which was a so-so decision. But the much loved 1999-07 had issues with the frames breaking after they had rusted for a while. This can happen to any frame tho, obviously Toyota is famous for it. The fully boxed seems like it would be better and in some ways it is, because the salt and water has a harder time getting inside the frame rail, but at the same time they don't drain as well should salt and water get inside. Add in some rust, dirt blocking drain holes it can cause issues that the normal C shaped frames didn't have. Actually That looks like almost the same frame they have been using since 2007 which was basically the same frame they used since 1999 but boxed in on one side. They are fine frames, the one weak spot is by the gas tank. The gas tank is almost pressed against the frame, this whole area gets packed with salt and rust and then the frame rusts out. This is nothing specific to GM trucks tho, but you gotta watch that spot. I'd pull the bed off once every couple years and just clean up that whole area around the gas tank. Pulling the bed off is pretty easy on most trucks. If it's a new truck like this one probably the first thing I would do is absolutely fill the entire inside of the frame with fluid film or pb blaster surface shield. You can use a pressure sprayer with the plastic wands, slide the wands right inside the frame rail and just go to town. If you do that once a year, your truck may last forever. Do the outside too of course but it's much more important to do the inside.
Are the GM 6.2 DI engine as good as you all keep saying they are? I work for a engine core supply and see the new GM design all the time. more times than not they have a big hole in the side of them with fragments of pistons falling out of them. Not to mention the lifter design flaw issue that was in the 2015-18's is still in the 2019 and later. I have always been a Chevy/GM guy but have no faith in their drive train these days. In my opinion the GEN III 5.3 or 6.0L 2000-2004 was the last reliable gas engine GM has produced. In 2005 GM decided to introduce a weak connecting rod. Why?? manufacturers got away from making vehicles that last to ones that have all the tech in the world but are not reliable at all.
I have owner F150s for the past 30 years. Last couple have had the aluminum body so I did not worry about rust proofing, like in the old days. I just purchased a GMC AT4X. It has 300 miles. Should I consider rust proofing for this truck? I do plan on keeping this one for the long haul.

I worked at the plant that made frames for GM as an maintenance electrician . Saw the entire process from start to finish. The frames are dipped in a tank of wax in the last stage before shipping. We shipped 22,000 frames a week. When stacked on the rail cars for shipping the frames already had rust spots at any point there was a small scratch or thin coating. Because it is dipped and on a hanging conveyor system the hot wax would run from the top to bottom and drip off. You can see the drips when looking at the back of the frame. The wax would be thinner at the front because it would run to the back as its hanging. They claimed it was self healing if stone chips damage it. Ahhhh NO.
Lmao I’ve heard of paint being able to heal it’s self when exposed to uv but a wax I think not gravity is still an issue. Not to sure why they don’t dip it from the front instead of the back seeing how the material motion of the vehicle is to move forward obviously having to deal with more elements at the front vs the rear. Guess the common sense wasn’t there.
My bosses friend brought his brand new Chevy truck over to show off. I looked under the frame and wiped off a bunch of rust around the Trans crossmember. Nice summer day, right off the lot! This winter I saw a 14 with rust bubbles in the fenders. In 2019 or 20 I saw a 2010 with rust holes in the bed fenders. If the 2014 sat on the lot 3 years, that makes the truck 5 years old with rust holes! Why would you buy a new Chevy? My 99 Tacoma looks like crap but it's been in a salt bath for 23 years. These Chevys won't be here's in 10 or 15 years. Where's the ROI on a 7 year old rust bucket that's still got payments? It's a financial trap in my opinion.
Ford did this for a long time as well, particularly in the early 2000s. I never understood waxing a frame. It's going to scrape off over time and then the frame doesn't have any protection at all.

Also Sarah-n-Tuned puts every vehicle she reviews on the lift she has in her shop.
Hopefully that wax coating will last the entire 3 months you own this truck.
RUclips .... we need new trucks to get more views per video .... time for another trade in !
LOL
😂😂😂
It last8 years and 135k on my 2011sierra until I sold it. You can touch up bare spots once and a while with any lanolin base undercoat, which is what that waxy greasy coating is.
Haha
Thank you for finally bringing this to the attention of the consumer. You cannot maintain this coating. As soon as it dries and cracks or chips form, rust then forms underneath the coating. You can't area sand and repaint like with an e-coated or painted frame because with paint you can tell exactly where is and isnt properly bonded/attached to whatever surface is painted through bubbling or flaking of the paint. Paint also resists that slow penetration of rust from underneath due to superior bonding to the surface. It is surely planned obsolescence with this in mind and the change to fully boxed frames. The actual material thickness is diminished from the start, then load bearing areas break much faster due to being so thin from the corrosion. You will not see trucks with waxed and fully boxed frames lasting and working hard for 30-50 years like you could previously with open channel frames or with current e-coated and properly maintained boxed frames.
i live in texas, i dont care lol
aka we dont have salt on the roads
in 30 to 50 years we'll be flying like the Jetsons or at least the Muskons!
Owning at least 12 Gm cars trucks. To still having 5 Gm trucks we run for business and personal . I've had no problems with motors , very mim trans issues only on the 4l60E, all my 6 , 8 speed trucks no problem down to rust nore paint issues. If you want a truck to last over 250k and up miles with out braking the bank. I strongly recommend Gm. Y'all can believe theses byest videos. Or real life ownership and work horse facts and statements. FYI this same so call truck review channel just did a video on the 2021,22 F 150 truck on how they had to correct Fords frame factory rust issues. When dealing with Ford trucks. This the same reason why I and people who own these trucks give motor trend, car and driver ECT real car long running review companies good consumer reports and ratings. Couse at least they aren't byest and call a spade a spade.
I appreciated Toby’s sticker shock. TFL needs to do a financing review of the best truck for your buck. Also best overall warranty.
Ford maverick
100% agree
Toyota
Great idea John!
As a collision technician for 30 yrs, hate having to work on GM frames.....that wax will make a mess of you, lol.
I despise the wax coating. I think anybody that works on their own GM truck will agree, especially in the rust belt.
Absolutely had wax is worse than if it were untreated. untreated it would at least dry out
One winter in Wisconsin and those frames turn orange with rust. Any company that does this needs to be called out and taken to court for selling an inferior product.
One of the reasons I went for the Colorado over Silverado was the frame coating, Colorado is e-coated, and Silverado is waxed. That wax is crap and rusts
This was cool, actually seeing stuff that isn't just the sales pitch.
This is the stuff RUclips was made for! 😉
It's great getting a mechanics eye view. Picking up on the practicalities of how the truck operates and its serviceability is important.
Love Toby, he’s a crusty 70 year old Mechanic trapped in a strapping young man’s body, he about stroked out at 65k, don’t take him in a F150 Platinum it would kill him when you told him the price and I 100% agree with Toby!!! Great show Andre!!!👏🏻👏🏻👏🏻
Just a PSA...this truck was made to enjoy trails and not zip past them in the desert while catching air. TRX and Raptor are a different class.
They are also 20-40k more expensive! Put that into a supercharger, roll cage and suspension... And this truck would compete. Fair enough?
PRYVTgomerPYLE 20-40k? The base raptor is 3k more....this is a base zr2 at 67k....
@@erikturner8687 you know this "base" zr2 comes fully loaded like the Tundra TRD pro. So what starts at 67k ends at 67k. The only other package is a headsup display which I would never get.
@@PRYVTgomerPYLE $20k? Man 420 is over
@@JattAnmoli that’s false but ok. Fully option ZR2 goes for 75k. fully option Raptor goes for 82k-86k depending on if you want the 37 package and blue seats. So that’s still only 10k. Not the 20-40k you guys somehow came up with.
I finished coating the entire undercarriage, interior, exterior rocker panels door bottoms with Fluid Film. The Frame on my 2022 truck has the same thick black coating both inside & out. It's a tedious job to coat all the vulnerable areas, but well worth the time if you live where I do. There is salt on the road nearly 1/2 the year. If you keep your vehicles for a long time & or live in the rustbelt you can't skip a treatment. It can be applied with a spray kit or a brush. I highly recommend it.
Completely agree. Sold my 1990 Dodge W150 2 yrs ago. Only drove it in winter, Maryland, PA, Ohio, heavy salt & magnesium chloride covered roads. I applied Fluid film in August or September every year. Only had one rust hole, (2” diameter”) on heal of RF fender. The hole was there when I bought the truck 7 years prior.
Gm's "rust proofing" is the worst in the industry
Can it be worse than Ford who already had rust when it was brand new
@@wesshepard yes….. yes it can.
@@SPPTA nope
@@hemal8569 I’ll just say in my experience, installing emergency equipment on these trucks, the GM “rust proof” coating get rubbed off by rubber grommets and wire loom….. the Ford while have some rust, have not nearly the same issues.
And you must be the expert?
Definitely would like more of these type of videos. Thanks Andre and Toby as always.
6:49 "See this extra brace..." I'm actually surprised that the lower control arm brace is bolted in rather than as stamped/cast. I suppose it's meant that way so that if the shock needs to be replaced, you don't have to drop the entire lower control arm to do it. Merely unbolting the brace allows enough room for the shock to be removed.
Previous recall horrors on the shocks make the removal easy for GM Techs.
It's just cost savings. That is the regular Silverado LCA made with two stamped steel pieces welded together with an extra tab welded on for the bracket. The Raptor/TRX use completely unique forged lower control arms.
So happy you guys got a ZR2. I'm hoping to get a 2023, maybe bison with the new diesel depending on output. I look forward to the tests and in depth exploration of this truck.
As a mechanic it is so unfortunate that new vehicles all have so many problems with reliability trying to keep up with emissions and fuel mileage standards. Brand new vehicles with less than 10,000 mi requiring major engine work is becoming normal.
Toby is a real gem. Glad you guys have him on the show.
TFL has been getting better and better. Really amazing content, covering all sorts of genres and interests dealing with vehicles.
Makes you wonder how much these manufacturers are fleecing us when the mechanic low balls the cost of the vehicle by 20 grand after looking over the mechanical aspects of the vehicle.
Good point. But the manufacturers (GM, Ford, Ram) are simply selling the trucks mentioned for what the market will bear.
The ZR2 Silverado appears to be a great off-road platform. But, since it lacks a wide-body, power adder, longer travel and 35 inch tires the price point ($67,000) seems high by around 7 to 8 thousand.
Also, that passenger side lower rear shock mount needs a protective skid plate ASAP. Maybe try sourcing one from the aftermarket for a Trail Boss? I know it's not the same shock, but it's worth a try before taking it out on any rough, rock strewn trails.
Oh, that smallish tank will ensure plenty of stops to get gas for that thirsty 6.2 V8. Sheesh, 24 gallons...gimme a break GM. Lack of a skid plate for said tank is not a big deal to me. An aftermarket one is probably better anyway.
@@billymc2681 this is true. You likely would be able to at least get a normal Silverado for 5-10k less than MSRP if it wasn't for this market we are in. Really sucks how unobtainable a lot of things are these days.
If you factor in inflation from what truck prices were years ago. Trucks are way over priced in the present time !
Even though mechanics know how to work on vehicles, most probably haven't worked in a factory where they are built and would really have no clue how much it costs to build a new car. Not saying the truck isn't expensive but lower volume parts on trucks like these do cost quite a bit extra.
@@kabloosh699 exactly! never buy a truck that you can't get 15 to 20 % off MSRP.
I purchased a 21 trail boss in May of last year, 3 months ago I got a new aftermarket bumper to put on. Behind almost every piece of bumper I removed was rust!! I have lots of pictures
I think they should of put skid plates on the fuel tank. If it’s suppose to be off-road truck, why not make it standard from factory 🏭.
Good thinking sir
My 2015 F-150 isn't even an FX4 and it has a skid plate for the fuel tank.
easy now...... they were looking at the plastic liner protecting the tank. it won't be a problem!
That was great! Do more mechanic walk arounds with new vehicles! There are so many things you just wont know about a vehicle until you get underneath it. Super helpful information. Would love to see the fleet get looked at.
Yea, that coating washes off in the high-pressure bay at your local car wash too, BTW. They you'll find a bunch of rust when Winter's over. My 2019 Silverado's frame has it everywhere I pressure washed. (Only once btw. I thought I was getting the salt off) Now I'm going around with a wire brush, and Fluid Film to recoat everything before it rots out.
Great video and I hope to see Toby make more appearances in the future. It’s a nice truck but interesting learning about it’s shortcomings and seeing them pointed out first hand.
I find their coating just falls off the frame eventually, ecoat seems to be the way to go if you're undercoating.
Read the owner's manual and you'll find out it shouldn't if it was treated properly. Treated properly to GM means rinse off the underside of the vehicle at least once per year and apply a new coat of the frame wax. Again, read the owner's manual.
@@domin8ss Apply frame wax yearly? Seriously? Thats acceptable to you when other manufacturers frames require nothing?
@@therealjohnsmith4811 This may shock you, but I check the air in my tire monthly, and change the oil regularly. There's more but I think you get the point.
@@domin8ss the coating dries out and falls off in places you can't get to. It's an awful engineering fail by GM. Not to mention that crud gets all over you when working on a GM truck. They need to paint their frames like other manufacturers do.
@@domin8ss I would like to see where it says that in the manual….
I'd like to see this truck vs a 70k Raptor. I just wonder how they would compare. I would think spending a few thousand more for the Raptor may be a better buy.
the only area i can think the zr2 will outshine the raptor is with the electronic front lockers. Im a chevy guy to the bone, that being said paying 3k more for a raptor is the way i would go. Wish this truck was in the 50k range and i would buy one. :/
@@lespaulplayer1234512 no truck with this capability in the segment is 50k unfortunately. Tremors and rebels reach 70k compared to what this offers and no one has front lockers in the segment
@@lespaulplayer1234512 you can get $10k off any daynof the week. maybe not the first few months, but sooner or later you can.
If you have to have a Chevy 4x4, please WAIT UNTIL the Chevy ZR2 Bison Edition comes out with all the AEV (American Expedition Vehicle) add-on parts. The Colorado ZR2 Bison Edition is today the BEST BANG FOR THE BUCK mid-sized off-road truck out there an the full-sized version I think will be just as good!
Just make sure you put 37 inch tires on it and it will match and even EXCEED a Ford F150 Raptor for overlanding/boondocking. I do know that BED PAYLOAD will be better by almost 400 lbs (181 kg) so that it a BIG SCORE towards Chevy! The V8 does give Chevy the ICE V8 Enthusiast's Edge but the Raptor has much better driving range and fuel economy with its twin turbo V6 so it will come down to WHO has the better price!

For what you get, the raptor is a no brainer compared to this.
I worked for Dana Corporation in Reading PA on the C,K and cab chassis lines among others. The GM frames were bare steel frame, washed, dried and dipped in a hot wax tank and allowed to dry hanging vertically with the front of the frame at the highest point.
So many factors determined how thick the wax coating was, summer vs winter, drying zone temperatures, wax temperatures, but always the coating was thinner at the front of the frame.
Then the heat of the exhaust would also melt the wax coating.
I thought they switched to E coat later?
Back in the day, a lot of people would take their new vehicles to a local Michgigan "Ziebart" shop and have the underside undercoated (spray on stuff). It also helped with sound deadening. Wonder if anyone is doing this or thought about it? I gotta 2021 GMC Sierra AT4 (6.2L, ALL options) and there is no rust or issues (Oklahoma truck). Sure it has some decent off-road capability, but it FLIES on the highway (up to 98 mph).
Check FordTechMakuloco/BSG Automotive. There is video of him removing Ziebart because it creates moisture when it begins to wear and then rust. With him and others (South Main Auto Repair) you'll see other recommendations for rust protection. Both are on RUclips.
Better off going with an oil undercoating early
I immediately had my trailboss undercoated with oil. That will always be your best defence against rust.
Looking at that shitty oil filter the undercarriage will be oil coated shortly.
That frame coating is garbage. They do not last and I don't understand why GM keeps using it. Also the lack of a skid plate under the fuel tank just blows my mind. They used skid plates everywhere else except there? This is why I don't buy GM products. If they are willing to leave things off like a skid plate under a fuel tank what else did they cut corners on that you cant see?
they were looking at the plastic liner protecting the tank. Been that way for eons. Nobody has problems.
I don't have problem in CA .
@josh
Why do you care what GMdoes with their trucks? You said you don’t buyGM vehicles
I have a 35 year old car with that same type of wax on the frame and it's still there doing it's job. That is some tenacious stuff. It's typically wax mixed with some other bitumen based ingredients. Only downside is it gets all over my hands when I have to work under the car.
first comment on wax that us factual....it lasts a long time.
2005 300k mile lly rust free florida truck. No issues with rust on frame.
@@rsbreeze unfortunately what ever they use on the Silverados doesn't last, many 2018-21 Silverados already missing quite a bit of their coating...
@@zoeyfaucett I'll give you $15k cash on the barrel head for everyone you bring to me!
Next time when yall take a drive anywhere look to see how many older trucks are on the road, count and take notes, how many fords? Rams? Chevrolet? Everyone says GM products are boo boo but then You see them all over the road.
But you said ON THE ROAD not all over the road 🙄
I have a similar coating on the frame of my 18 Silverado 1500. It has held up well. 75k on it and no degradation. 0 problems with my pickup. Only required oil changes and regular maintenance. 5.3L delivers excellent fuel economy
Same experience here and my 2018 sits in a carport right on Humboldt Bay. No rust on frame - yet.
Move to minnesota, solid rusted frame on my silverado in 2 years.
My 2018 GM truck frame has far more rust than I’d like to see. At first I thought I would not have it too long since I drove it a lot. But, now that gas prices are so high, I bought an EV and do most of my driving in that, and just use the truck for truck things. It may be with me for longer than I thought. I now am more concerned about rusting.
fluid film
I really like that mechanic he was very very cool! Wish we had more like him in my area Grand Rapids Michigan.
Wayyyyyyyyy better good looking than the Yotaaaa👍👍👍
Good job Chevy! I believe Ford's under carriage rust issues are primarily due to having vehicles sit out in the elements for weeks if not months before chipping and shipping.
Bullcrap. I live in Ohio & GM vehicles rust out significantly quicker than Fords. You're both lying.
GM did the same thing with Silverado/Sierras during the supply shortage. People on the subreddit showed pictures of rusted frames from the dealer because the trucks sat out for months in the elements near the assembly plant waiting for parts.
The coating on my 2019 Colorado was actually really good and held up well the couple years I had it. Northeast winters are harsh. Got my new Silverado Rust Checked and will continue to.
Leaf springs, forgotten skid plates, and GM cost cutting specials. Don’t forget the engine destroying lifter issue that they refuse to fix -> way over priced. The mechanic estimated the value of the truck correctly, but got the price wrong.
All I know is that the frame on my 2007 Silverado that has spent the last 238k+ miles on northern roads with salt all winter is just fine. No significant rust at all. Granted, it's not driven off road,but it is driven and driven and driven.
Yep my 2000 Silverado no rust in Colorado
I know a guy that moved to Guam that had his frame break on his Silverado during a simple right turn with no load or trailer. He wasn't recoating the frame annually like GM says to do in the owner's manual.
Keep an eye on the inner frame in between the gas tank on those I see them crack there in illinois on the second gen silverado I have a 2011 silverado with 220k miles myself and just has surface rust on the frame the bedsides are gone though
Had a 2007 also not rusty frame

Syracuse,NY guy drives a Plymouth Valarie daily all year (winter salted roads) he coats the whole car with transmission fluid. The car has no rust and I mean NO rust.
Please tell me it's the wagon I had one as teenager in the late 80s it was very fun car put 230k on it before frame rotted out great memories in that car
Near Syracuse, we get a lot of salt, so I'm surprised the transmission fluid is enough. That's pretty cool though, wonder if I'll see him
@@agent_bedrock5844 mine was ne Ohio on the pa line the snow and salt is terrible on them
That’s an old farmers trick. Afterwards they would drive it down a dusty road until the undercarriage is completely covered with a layer of dirt. Cheap and extremely effective way to prevent rust from forming.
anyone ever wonder is it's planned out like that? I mean, with all the tech we have now days, we still use salt. I think, the manufacturers have a pay out with the states lol. vehicles rust and have to buy a new one. circle of life.
Here in Maine, the wax coating dries and flakes away revealing how thin the actual frame is , and usually a bunch of rust underneath.
Fluid Film will make a HUGE difference at keeping rust at bay.
HATE all the gloss black on the front and rear bumpers🙄. What are auto makers thinking by adding all the gloss black trim when they know it will easily scratch and get damaged??
I work at the Oshawa Gm assembly plant where we assemble the 6.6 duramaxes and 6.6 gas and soon 1500’s… this coating is so annoying I would rub so much of it off to the bare metal in so many spots
They still add the wax because they want you to buy a new truck every few years
Wax on ...... wax off
Spray everything with PB Blaster Surface shield. Great stuff!
Definitely do more of this style video.
Have a 21 trail boss 10k miles so far! Love it great truck! No issues not rust. Traded an 08 with 275k miles no issues and very little rust.
Dont understand that wax coating. I have a Tahoe that has the same thing. It seems to attract dirt and grime and just comes off exposing bare metal if you barely touch it. GM could have spent an extra few dollars and painted the frame or better, power coat.
LOVE seeing the truck up on the rack like this. Please do this with ALL trucks you test.
Fluid film is the way to go. Use it before winter every year.
Great Video we need more like this one that can really go into detail with everything underneath

Is there a skid plate available for the catalytic converters area like the Toyota trucks? I'm in an area where converter theft is high. Thanks in advance.
GM started dipping the frames of the full Size trucks in 1999 when the GMT 800 was introduced. It's a hot wax style coating, not a spray on coating as your Mechanic friend mentions .
I think it would be cool to see him look at the trx because you guys have had it for over a year
I discovered the wax coated frame crap this past weekend. Who at GM thought this was a great idea? It is stick when working on it and comes off when jacking it up.
All the talk about surface rust on axle tubes and frames is laughable to me. Living in Canada and driving pickups for over 40 years I have never had an issue with a rusted out frame or a problem with an axle because of rust. Many of my trucks made it to over 2, 3, or 400,000 before they were sold or retired for good. I can only imagine how much road salt they were exposed to where I lived. Most of my trucks were Fords with the odd GM or Dodge in there starting with models from the 60's all the way to the present where I own a 2015 F350 King Ranch and a 2005 Tacoma that I drive the most out of the two. The Tacoma is dead nuts reliable. It has rust on the frame as you would expect but at almost 300,000 it is still not an issue. I give it a spray with the wash wand in the right places when I wash the truck. Have looked at it where it is most vulnerable and it is no where near rusting through. The 2015 King Ranch is the first truck I ever had undercoated and rust proofed because I plan on keeping it forever. People fretting over surface rust on an axle tube under your truck is really unnecessary.
The issue isn’t the exterior frame coating. That is easy enough to maintain.
In the northeast and midwest, it is the salt brine that rots the frames and cross members from the inside out.
The key is to get the interior frame members coated.
My preference is NHOU and if a brand new vehicle the boss wax and seal is great. Lifetime warranty and touch up internals of frame and body every other year for daily drivers or every year for our plow trucks
The back to black and clear coating work great for not new vehicles.
Fluid film and woolwax are also good products.
But you have to treat the internals otherwise the outside will look good, but can be paper thin
$45? That guy doesn't get out too often.
No he was stating what the actual value is. LOL
More please...i want to see the bottom of all vehicles that you can get your hands on.
Thanks, Andre for a look at the underside of the ZR2. I was down working in Souther Cal (Ontario) this last week and weekend. I did find a ZR2 on at a dealer nearby. There "Market Price Adjustment" for the ZR2 was $10,000 making it a $80,000 truck. Too much for my budget. Looking forward to more videos on the ZR2. I don't think it's direct competition to the Raptor or the TRX. I want to see how it stacks up to the Ram Rebel, the F150 Tremor, The Tundra TRD Pro and last but not least the Titan Pro-4X. I do realize that on paper some of these trucks are more capable offroad. But real-world testing will show if that is true.
Add to that tax license interest and all the other incidentals dealers tack on and you have a $100000 1/2 ton truck. My coworker was looking at 1/2T about 6 weeks ago. He told me it was $116000!!!!!! HOLY COW.
Now where is the 6 speed manual, that's where they are REALLY REALLY dropping the ball with pickups.
I live in Eastern Canada and theses gm frames rust like crazy. Theses wax dipped frames are garbage.
I love the truck but I won't buy a half or three quarter ton until they make a nice manual, preferable with a long throw.
Amen to that. The new automatics are nice, but a good manual will do the job too. I grew up driving them and took my drivers test on a 62 Ford Farlane with the 3 on the tree manual...in 1982.
It doesn't make sense that the Chevy has such a small fuel tank. The 2017 F-150 I had super crew had a 36 gallon tank so obviously that can fit under there because it had a similar size box.
The 36 gallon tank is part of the towing package. I assume they withhold the larger tanks so that consumers are forced to buy additional add-ons. Just like Ford not putting auto climate controls on anything lower than the Lariat trim. Remember when cars didn’t always come with passenger side mirrors? It’s all about the upsell.
Makes no sense that my 2018 Colorado has an electronically dipped frame while the Silverado is still rocking a coating as the main truck lmfao. I thought with the LAST model of Silverado would address this. Two updates later and we're still seeing this.
Great video of the underneath of the ZR2. Enjoyed hearing Toby’s expertise.
Thinking about it today ( it was 20 years ago I worked there) I think they did put them in front first. I recall they hooked them by the "rear mod" as it was called and lifted up on the conveyor . After the dunk they went through the "cooling tunnel" to cool the wax. To be fair I am on my 4th GM truck in 20 years and looking at my 5th. I guess I am a fan. All steel will rust in a few days when exposed. Then put it through snow and salt for a few years pretty tough to do anything to stop it. It sucks but look under any truck they all suffer the same problem.
I have three GMCs and one Chevy truck currently and every one of them have extensive rust on the frames even after treating them with Fluid Film spray every fall. I live in Idaho, so not too severe winter, but they sand the roads. Three of the trucks are 3/4 ton trucks and I have to wonder how much load capacity is reduced by rust on trucks all across the US and Canada. There really should be a class action lawsuit against the big three because of the rust all of them suffer.
Anyone know we're haven't answer of why GM is still sticking to leaf spring in the rear? Other manufacturers have gone away from it and doesn't seem to have hurt their numbers for towing and payload
Leafs are cheap and GM doesn't want to spend the money on R&D.
Not a fan of gm but I really like the color
Yep it has at least something going for it
Its pretty lame that GM still isn't e-coating their frames. Compare a 5 year old GM frame to a Ford frame, and there is a stark difference.
GM needs at least a 32 gallon tank. The size of that tank is BS.
Long bed trucks get the bigger tank short beg gets the 26.
I just got a 2022 Silverado. I plan on doing yearly lanolin sprays under my truck.
That exhaust pipe being so close to the transmission should have had a heat plate your going to burn your trans oil overtime and im sure itl affect the transmission as well probably will have to do closer trans fluid servicing than normal
That type of wax coating is "Nox-Rust" made by Daubert Chemical (although GM may have their own even cheaper generic version). I remember this being a PITA back in the '70s and when I bought a new 2010 GMC, I was surprised to find the frame was coated with that cr*p. As anyone who has ever worked on a GM vehicle with this coating on the frame knows, it's a real PITA because it constantly rubs off on anything & everything that touches it, especially in hot weather. And it's an even bigger PITA (more like nearly impossible) to remove all of it from every nook & cranny of a frame; you practically have to dip the frame in solvent to get all of it, but if you don't clean that stuff off, nothing applied over it will ever adhere any better than that stuff (which is to say, poorly).
Have you ever done this before, if not, please keep doing this. I love seeing the engineering beneath. Seems like they should have a Carbon fiber skid plate for the tank to avoid sparks, a skid plated for the rear diff you like discussed and should the tranny have some sort of skid plate or is it just high enough that it doesn't need one? Also, I see you didn't get the rock rails on this. Why doesn't GM do disconnectable sway bars like the rubicon?
No reason to.
MSRP JUST WENT UP 1500$ TODAY you bought at the right time!
This truck is beautiful it just needs bigger tank "24 gallons for a truck aren't enough especially for 6.2 engine" and lower price.
I know right trucks should come standard with a 36 gallon tank. I have a 36 gallon on my F150 I’ll never go to the smaller tank when I get a new one imagine if you were towing with a 24 gallon tank Jesus
I have a 2017 2500 with 100,000. It is used to plow snow. No rust anywhere. Coating is holding up good.
Seeing what we are getting brand new is great..
Sets TFL apart from the rest..
No BS review
I just bought the 2022 refresh trail boss with the diesel and absolutely love that thing
That's mexico's best truck yet.
I've got a relative with a 10 year old (130k mile) gm pickup and the rear quarters are already pretty much gone. The thing is a rust bucket. This is in the midwest salt belt.
I drive a 7 year old gmc sierra with 128 k on it in Buffalo ny. Road salt is spread out every time it snows. The frame has surface rust but the body is perfect. If you take care of your truck it will take care of you.
Owned several GM trucks, never had a problem with the coating on the frame. I had an '85 3/4 ton Chevy, best truck I ever owned, probably better than any new truck today.
Throughly enjoyed this video. Very informative!
Nice looking but IMO GM didn’t one up the trail boss enough. Hopefully the power plant takes you past 5k without bent rods or failure.
Y’all are seriously trying to take jabs at GM’s new trucks and their reliability when the 2022 Toyota Tundra is experiencing rear axles popping off mid-drive? I just think that’s hilarious. Truth is, every truck in this segment has had some type of issue or 2 - some more serious than others. This video is about GM mitigating issues like rust from happening though. Just funny the comments are talking about the skepticism of a brand new _2023 Silverado_ barely reaching 5k miles before experiencing unprecedented and catastrophic *failure* even though we’ve witnessed this already with a brand new truck it just wasn’t a Chevrolet.
Picking mine up in 2 weeks... this was super helpful!
In NH the silverado is rusted in a couple years. The undercoating needs to be done every year or every other. The new PB blaster undercoating is legit. I use that, Fluid film or NH oil undercoating
add yourself a heat shield over the exhaust flattened tube between the trans pan and the exhaust. airflow at speed will work to cool, but off road, why in the world would you not keep the tranny fluid pan from absorbing all the exhaust heat in that location.
Need to dip the frames in the same electroplating they use to protect the bodies and then coat it again
Agree. Colorgalvanizing should be the standard.
That all looked pretty nice to me. But damn that price tag....idk for that I'd want a diesel. Price aside, looked like a fun solid truck. It's remarkably similar to past generation Silverados. Starting in 2007 they went to a "fully boxed" frame which was a so-so decision. But the much loved 1999-07 had issues with the frames breaking after they had rusted for a while. This can happen to any frame tho, obviously Toyota is famous for it. The fully boxed seems like it would be better and in some ways it is, because the salt and water has a harder time getting inside the frame rail, but at the same time they don't drain as well should salt and water get inside. Add in some rust, dirt blocking drain holes it can cause issues that the normal C shaped frames didn't have. Actually That looks like almost the same frame they have been using since 2007 which was basically the same frame they used since 1999 but boxed in on one side. They are fine frames, the one weak spot is by the gas tank. The gas tank is almost pressed against the frame, this whole area gets packed with salt and rust and then the frame rusts out. This is nothing specific to GM trucks tho, but you gotta watch that spot. I'd pull the bed off once every couple years and just clean up that whole area around the gas tank. Pulling the bed off is pretty easy on most trucks. If it's a new truck like this one probably the first thing I would do is absolutely fill the entire inside of the frame with fluid film or pb blaster surface shield. You can use a pressure sprayer with the plastic wands, slide the wands right inside the frame rail and just go to town. If you do that once a year, your truck may last forever. Do the outside too of course but it's much more important to do the inside.
Are the GM 6.2 DI engine as good as you all keep saying they are? I work for a engine core supply and see the new GM design all the time. more times than not they have a big hole in the side of them with fragments of pistons falling out of them. Not to mention the lifter design flaw issue that was in the 2015-18's is still in the 2019 and later. I have always been a Chevy/GM guy but have no faith in their drive train these days. In my opinion the GEN III 5.3 or 6.0L 2000-2004 was the last reliable gas engine GM has produced. In 2005 GM decided to introduce a weak connecting rod. Why?? manufacturers got away from making vehicles that last to ones that have all the tech in the world but are not reliable at all.
First deer season and that frame wax gets wiped off by the sage brush. But a 6 pack case of rustoleum for touch up
I have owner F150s for the past 30 years. Last couple have had the aluminum body so I did not worry about rust proofing, like in the old days. I just purchased a GMC AT4X. It has 300 miles. Should I consider rust proofing for this truck? I do plan on keeping this one for the long haul.
Wouldn’t hurt...all the hinged panels are aluminum on that truck, so doors hood and tailgate should be good
Who cares about the body. Its the frame id worry about.
I was referring to Zeibart's frame coating.
@@erikturner8687 aluminum won't corrode through but the paint will pop.seen this on jeeps aluminum doors.
