I have seen his channel. He does click bait to get paid. He also loves the 3.0. But at some point when they mentioned that belt, there was buzz, and it caught fire. So he did a video regarding the fear feedback. Mind you this does not negate that the truck at that point had not even been on the road yet. There was a "concern" of old men researching a purchase. Based on nothing. Unlike the LS motors and the LT motors and present day with immediate motor issues within weeks and months of release- bending pushrods, wiped out cams, stuck lifters on brand new trucks and cars. That is called "an issue". Quality control, design flaw whatever you choose. But that "issue" is based on ongoing problems people are having. Its real. Its a fact. Its happening. There are memos from GM to replace all the lifters on new trucks. The oil pump belt on the 3.0 is working fine, and there has not been an issue. After seeing where the belt is in the video and figuring the job whenever that comes....looks like a walk in the park. Regurgitating someones "feeling"..is getting old. Its someones opinion about a feeling that they feel may happen or could and then make up numbers and statistics........on nothing. Just someones feeling. I like facts, not feelings. I'll listen to an opinion...based on facts...feelings are for woman. I have owned many 5.3's and 6.2's. I could name 10 different jobs guys arent going to do on that motor also. Knowing GM well from experience...the rear seal leaking is the only "real" problem that has occurred with this motor and it was early on. No new trucks have that issue. The crank no start has been solved with software. It is unusual for Gm to do so well with any new motor. But its out since 2018 and it appears they have. It is shocking too. Please post that failed belt and blown motor in a 3.0. I have been looking...can't find it. I have found thousands of cams and lifter jobs throughout the country to the point where they cant even keep up with parts to fix them. We loved the new Yukon Denali very much after a test drive. We couldn't find a 3.0 Denali, I almost caved in and bought the 6.2 that was available. So happy I didn't. Lucky we fell into a Denali CC 3.0

Kind of a waste ponying up the extra cash for the 6.2 and then preventing it from performing to it's abilities by running regular fuel.

NO! The 6.2L motor is designed for maximum performance, effectiveness, and longevity with 91+ octane. Turning off DFM will not do a thing for the use of premium fuel. If you are worried about premium fuel, I suggest a 5.3L with the 10 speed. Step dad has it and loves it.

I thought that maybe I was just being dumb and that it has always been like that, but my average seems to be way up. after driving around town for a couple of minutes my last 100km average is over 20L/100km (11.8mpg) where as it always used to only go up to about 14L/100km (16.8mpg). Maybe I'm just looking at it to hard, and its nothing. I don't know...

I had a Corsa Touring Cat Back a few years ago on my Yukon and loved it. Awesome, throaty sound on acceleration and quiet while cruising. My new AT4 came with the GM Performance Exhaust which is the Borla exhaust. It sounds ok, but is much quieter than I was expecting. If I had a choice I would go with the Corsa. It definitely sounded better. And FWIW, I prefer a quiet exhaust, but the Borla is too quiet if you want a performance exhaust. I only got the GMPE on this truck because I had no choice.

Hi all. I just took delivery today of my 3500 Denali from Reno NV. Order was placed on 8/10/21. It's been a long time coming but it's a good day today! I didn't get heated/cooled seats ($200 credit) or upfitter switches. Everything else is pretty much as expected. Best wishes to those still waiting. Hope y'all get it soon.

Im glad mine didnt come with DFM and I just disabled the AS/S yesterday.

Not following the logic of wanting to add back in a tensioner. The stretch belts have been on the AC compressor and vacuum pump on the 14-19 trucks and they worked great. The serpentine stretch ones are doing good on the 19+up trucks as well. No more failing tensioners like the LS motors always did. Adding in the tensioner costs more than a new belt and the install tool that you buy once. Using MSRPs, LS 5.3 belt and tensioner $176.60. 14-19 LT 5.3 engine $109.30. 19+up 5.3 stretch belt and the one time purchase of the Lisle installer linked above $88.15. Even using Kaden Seidel's approach, its much more than the tool and the stretch belt. The pulley and the tensioner alone he used MSRP total $97.61 and that is NOT including the belt he had to get. For him to say its cheaper than one stretch belt and installer is wrong.

Hi. I've got terrain trails 20in. on a 2020 elevation. I like em there quiet and smooth. Seem to be a very sturdy tire. Haven't had them on any slick stuff yet. I really like the looks to.

Not at all. God, not Washington, provides for our needs. I'm not going to downsize or drastically alter our driving habits because of those Commies.

Check your clutch air gap for being excessive. One test. Be very careful! While engine running, AC on, but clutch not engaged, tap on the face of the clutch. If it engages. Weak clutch or excessive gap

Somebody fill me in on where we are with this. Do these windows still leak into the late 2021/ 2022 models??? Had a 2020 built in July 2020. It had a slight leak. I added TrimLok weather seal tubing to the spoiler gap and never had an issue after that. Truck got totaled. 2022 is being delivered next week. Wondering if I need to do the same on this truck.

Several months ago, I was towing my Camaro to California from Utah. Along the way I got a wild idea to stop at the base of a grade and see how she performed. While I didn't completely stop, I did put it in a bad situation and I felt she performed very well. Temps were already warm since I had been driving through the 110+ degree desert for several hours. Hope you enjoy ! Love that 3.0 Duramax !

All newer vehicle have an anti siphoning fill tube. Try to put a hose down there. It wont go. Thieves are now, just drilling a hole in the tank with a cordless drill. Many recent reports of drilling. Have to really think about where your leaving or parking your car/truck. About all a locking cap will do is save you from someone adding something to your tank....like an ex girlfriend adding sugar!! LOL

Just so we are accurate the 5.3's have 11.0:1 compression ratio and the 6.2's have 11.5:1 compression. That .5 in compression doesn't really make that much of a difference. Yes the 6.2 will make the most power on 91+ octane but running 87 or 89 octane can be done and people do it all the time. I've seen data logs of 6.2's on lower octane fuel and they do fine. Sure it spark knocks a little bit more only under heavy load but the computer can handle that. The engine doesn't know what octane it's running when at cruising speeds where people spend 99% of their time driving.

AS/S Eliminator installed. No more having to even think about it.

Slide, thank you for all of your content here, you will be missed. I hope you enjoy your new ride!

Why do people keep regurgitating this nonsense?? Its based on nothing. Its also not true. And its said over and over with no factual reasoning. First of all to clarify its 150K service recommendation....and GM has in print, said they will probably be extending this to 200K. Not one belt has had an issue and there is not one person on the internet that has done this service. It can easlity be viewed though the same lense as MANY cars on the road right now that have a sevice interval for a timing belt. 60K 100K 150K is the norm. That is a much bigger, more complicated job, with alot of skilled labor. This service is easy and trans only has to be slid back to access the belt which is on outside of all timing belts. Remove and replace. Literally a couple of hours at most, 100 bucks an hour, lets say under 500 bucks in 10 years and up to 200K away!!!!! Have you looked under this truck?? There is tons of room and its an easy job when it happens. Ever do a water pump and then think hey while I am in there let me change my serp belt, and all the tensioners?? This will be the same thing when trans work or a torque converter which seem to be very common on any GM truck in the last 10 years. Please stop repeating false info. This is a nothing burger. The lifters that go on much more on gas trucks will cost 3 times as much out of warranty. Think about it...how could a 50 dollar belt and sliding the trans back cost over 2ooo dollars?? Ridiculous. Not one issue to date, truck is out since 2018. To do lifters on a gasser is about 2-3 days, removal of the heads, and front of motor, remove the cam and inspect, replace lifters, replace pushrods, and put it all back...that is thousands of dollars! All 2021 GM 5.3 and 6.2 will need new lifters as per GM. Most guys stating this probably dont even realize their wifes car has a service interval for the timing belt........ This belt is of no concern.

I have had a lot of trucks. This truck impresses me every time I drive it. Its so well rounded and does everything well. Definitely a superstar in the lineup. Good to see people working it, and using it as it was designed. I only pull 5500 lbs open trailer and feels like such a lite load with this truck.

I honestly think it does fine on the highway but hey, I came from a 2012 Sierra with the 4.8 that I bought new and drove for 9 years.. my duramax feels like a little rocket compared to my 4.8

Dunno about that one.. when I drive, it's a steady foot on the gas pedal. Downhill, I hit 85 mph, uphill, I try to stay above 50 mph, I wish cruise control was based on my foot pressure because I live in a hilly area and when it gets too steep, the cruise control forcefully mashes the gas pedal. When I drive a long distance, I treat the left lane as kryptonite. I use it very sparingly, once I pass a slower vehicle, I get back to the right immediately.

Slower you go, the better the fuel mileage. Anyone telling you otherwise is wrong. Yes, slow speeds are not at all practical. Yes, I agree that in some traffic situations it is necessary to run faster than you might otherwise. Yes. I agree that time also has value, and sometimes it's not practical to run slower. Cruise is your friend. All vehicles/engines are gonna give better mileage if speeds are steady. If you have an area with light traffic and long stretches with little to no grades and little to no elevation change it's no to hard verify. Lots of areas this type of comparison is not possible. The 25 mile average DIC page can be useful if watched often often/long enough. It's easy to be mislead by it if only watching for a short period. Nearing 18,000 miles. I log every fill. 'Life of vehicle' mileage currently about 24.7 usmpg. At the end of the day, the question is what time/mileage ratio works for you?

Thanks and I dont think you are grumpy at all!! But thats the information I was trying to confirm...that is.........A lower the number would mean more idle time or more city driving had occurred, which is harder on the engine than a higher number would be, that would represent more highway or commuter miles. (Correct?) I just bought the truck for 32k, and those were the engine hours. 2014 GMC Sierra SLT

Our '21 5.3 8-speed truck does the "first shift of the day" 1-2 slip/clunk. For reference, I always let the truck warm up for a minute or two before backing out, and always come to a complete stop when shifting from reverse to drive. Today I tried your trick (leaving it in neutral for three seconds before shifting to drive) and it didn't do the 1-2 slip/clunk.

2021 5.3, 8 speed. My dealer finally replaced the valve body and there have been no problems since then.

His point is this is a new truck, it should have no issues. Who would tear a new truck apart? Good grief.

New guy here, so, I'm sorry if this has been covered before. Looking at ordering a 2022 Silverado RST with the 6.2L L87 motor. Recommended fuel is 91 octane. If DFM is disabled, would it make sense to use 87 octane fuel? Bottomline...is the 91 octane directed because of the DFM causing cylinders to shut down? The 6.6L gas motors in the 3/4 ton HDs do NOT have DFM and their recommended fuel usage is 87. What say you?

My 2020 corvette recommends High Octane fuel also, I run 87 as I only drive on weekends and not a big hurry, I believe unless you’re on the strip you will have no problems . Knock sensor will make fuel and timing adjustments long before the human ear can hear it.
