Car Care Nut -Why you shouldn't wait 100k mi to change coolant on a Toyota UR series V8.

You're certainly entitled to not like the layout and format of the video -- and I tend to agree -- but you can't criticize the topic or technical content you haven't watched.
If you feel it's a waste of your life, I get that. Then just don't comment at all -- not because I don't like your position (I sympathize with it) but because you can't form cogent arguments about technical info you haven't viewed.
If you want to form an ad hominem attack against CCN, that's fair, but doesn't forward knowledge of head gasket failures.
I'm not attacking you personally -- merely holding you to the standard to which I've seen you hold others on this board (which is a good standard IMO)
clickbait.
a head gasket failure at 200k really unknown use and abuse miles is really not all that bad.
Recently, i opened up the valley of my 5.7 and the aluminum was pristine, so by this account, i should be fine right? who knows.
really, if this was a known thing by a master toyota tech, i kund of find it silly to even go down the road of head gasket replacement at 200k anyway, if the impossibility of machine work on the block is so dire.
with that time spent on tear down, he could have already got a new engine.
i love the," well we tore it down this far, but i cant warranty it" thing.
It's YouTube, and as such people aim to make their videos as long as possible in order to maximize the minutes watched. This causes a significant degradation of signal to noise, making it less and less of a resource. Ymmv.
So at 200k, the engine should have completed it's second coolant life cycle. Who knows what the shop doing the first change used, if it was in spec, or if they added stuff from BG to make it break extra after the upsell. You're going to have problems if put in 80's era Prestone coolant mixed with tap water and run it for 100k.

You make a good point.
I watched the first 10 minutes of the video in regular time. I tapped through the rest of it, seeing if he actually had a point. So I did in fact, watch the video, but I didn’t catch every word.
It’s not an ad hominem attack to discuss the product that somebody creates.
He filmed it, ostensibly, he edited it, and then he chose to publish it. The result of that work is what we’re discussing. Not the man.
You’re right, I don’t like the video. It’s junk.
But nowhere in my posts did I criticize him personally,
That’s an important difference, and that is part of the gold standard to what you refer.
I started watching it with interest as an owner of a vehicle with that particular engine. If he has a point, I’m interested.
At the end of my effort, and despite all of the post here, I’m still struggling to find that point.
I have yet to see a cogent summation of his point.
Just the 1.18 million subs "in the fan boi camp".
I think the point is, there are good points and there are "making money from YouTube" points.
"I've seen a lot of this" is not a valid statistic, but may get clicks. As you point out, he is getting good at getting clicks from his 1.18M subscriptions.
CCN seems very genuine. Maybe you disagree, but unlike most people on YouTube, he's actually staking his reputation as a Master Tech behind it. This is not like some random guy on their farm/in their barn with nothing to lose.
Are anecdotal UOA's a valid statistic?
This is not a man that is out to rob you of your "clicks".
Now read the rest of my post where I clarify my position.
I'm just pointing out that n≠1 in this case.
And?
How many of these engines have been built?
How many failures have happened?
How well were the cooling systems maintained on those engines?
Since you can’t answer all of those questions, you can’t establish a “trend”, and a “trend” is what is being claimed here.
I think (<-----this is the first problem) he's genuinely frustrated that:
1) this is happening at all. We know from results Toyota can do better
2) he has to have these conversations with his customers. I guess it's part of the gig but I hate telling people a car worth $3k needs $4k worth of work.
I believe that frustration and even hesitancy leads to the rambling nature of the video.
Again, I'm inferring his beliefs, feelings and ethos here. I could be wrong and he deliberately made a rambling (sorry, but it is) video to maximize monetization.
Each will have their own opinion. I don't envy him having to explain the problem and costs to his customers.

Nah that's good. The coolant has a tough job
He says these repairs are trending up in his shop. He goes into detail about acidic coolant eating away at the small tolerances separating the combustion chamber from the coolant passages. Presumably, he has access to each vehicle's service records. If there were anything remarkable to point out, I'm sure he'd tell us.
In his mind, and as @D60 pointed out, I think CCN wants to see zero instances of these because, as a Master Tech, he believes they are avoidable with early and often maintenance.
What is the problem? Isn't that what BITOG espouses? Early and often maintenance? OCI's? If you want to talk about fear mongering...

I agree with that part. He did explain the aluminum block and aluminum heads with the MLS steel gasket in between being the main reason....and the fact that it is always the same 2 cylinders it probably would happen no matter what given enough hours of run time with heat also being a factor. But if there is any chance it could prevent it I would be changing the coolant.
To me this reinforces the issue with making conclusions about reliability in the first 10 years an engine has been produced. Some problems don't start to show up for a number of years.
Head gaskets can and do sometimes fail on the gm ls engines as well but there is a huge difference in the price if it happens to one of them.

He has some good videos. But man, he can be insufferable sometimes, especially talking about BMW.
What really caught my attention that often he talks things he doesn’t understand is when he blamed “European “ solutions to new Sequoia cooling fan design, which no European manufacturer uses.
He is becoming more sensational as money is good.

I don’t understand all the negativity here for CCN. He’s one of my favorite automotive YouTubers.
I think he wants to sell his services, has accumulated 4 paying customers to the tune of $10k+ which he accumulated through his YT channel.
I'm not criticizing him for trying to make money as a mechanic, but like @Astro14 says, no hard statistics, and i take it a step further with scare tactics claiming there is a trend when the only trend is his customer accumulation.
Like others have said, change your dang coolant. These folks probably didnt.
