Suggestion
DCA or SCA tablet are important for HD diesel coolant, but should only be added after checking coolant with testing strips, important to eliminate cavitation and also protect cylinder liner from impingement during combustion that will eat away on the liners.

There is no such thing as 100K engine oil change for HD diesel, fact is oil change interval were reduce in 2007 after oil TBN was reduce for the aftertreatment life increase, now there was a system that allowed long life oil changes in HD diesel which would run the oil from the engine thru the fuel injection and replenish new oil into the oil system as your driving down the road.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

There are failures in cooling systems due to wrong chemistries. Anyway after I talked to an engine builder who told me what coolant to use on my car, I talked to the chemist that formulated the stuff. The aftermarket coolant for our cars is Del-cool, yes GM , Japanese technology. Don’t use zerex G-40. That’s good for 2010 and after. Anyway depending on the engine metallurgy you have different coolant chemistries, silicate free etc. You can have OATs , that’s organic acid technology, HOATs hybrid organic acid technology and a bunch of other stuff. If people don’t understand motor oils less they are going to understand coolants. These are tested in engine labs with a lot of time and effort. Diesel engines run a lot hotter and yes they use different coolants. Some Diesel engine coolants have particulate filters and a tablet
similar to a detergent that dissolves over time. Also on some cases you have a Diesel engine coolant that is good for 250,000 miles then about that time you are good for another 1 quarter million miles before you flush the system.
At 250,000 miles you add the additive treat. FYI, I�m taking about eighteen wheelers, remember every time you take one out of the road you are loosing income. That�s why there are some 100,000 mile engine oils and drains for the heavy duty trucks.

You do know that Porsche does not manufacture that stuff??? Every time Porsche puts their brand name on something price goes up by a huge amount. I�m surprised they are not selling Porsche branded
toilet paper and hand sanitizer.
They do sell these:
But I'm pretty sure they're made by a little old lady in Stuttgart with her sewing machine.
The bag of course she made by hand.
Danke Oma, dass du meine Handschuhe gemacht hast.
Tsch��!

There is no such thing as 100K engine oil change for HD diesel, fact is oil change interval were reduce in 2007 after oil TBN was reduce for the aftertreatment life increase, now there was a system that allowed long life oil changes in HD diesel which would run the oil from the engine thru the fuel injection and replenish new oil into the oil system as your driving down the road. outlawed by the Fed's many years ago.
DCA or SCA tablet are important for HD diesel coolant, but should only be added after checking coolant with testing strips, important to eliminate cavitation and also protect cylinder liner from impingement during combustion that will eat away on the liners. the tablets only come in water filters or liquid additive.
The system that you are talking about was invented by Cummins and you needed to order that in, the oil that would do the 100,0000 interval was Cummins premium blue extreme manufactured by Valvoline. Synthetic truck engine oil. Anyway yes after the different after treatment oil change intervals where reduced. I had personally taken care of fleets that had more than 1000 trucks. I have been retired so I�m not 100 percent up to date on certain things I do have my co tact�s and knowledge. Another thing that happened was ultra low sulphur diesel , sulphur was a natural lubricity additive, anyway I�m certain that a bunch of stuff has changed, but friction and wear and chemistry pretty much stay the same.
sir gasoline engine have spark plugs they need that to ignite the fuel mix. Diesel engines explode by compression. Look at a Diesel engine piston and block of the same size, they are a lot heavier thicker, etc etc . Check the compression ratios. Ask somebody that knows about cylinder temps. As the engineer at Valvoline told me to day, next time you talk to the mechanic that you where talking about rebuilding your engine and told you to use Zerex G40, which university he went to to get a chemistry degree and where did he tested that. Anyway piece of advice not one coolant for all applications.
I use pentofrost in my car and it works just fine. I went with it because of availability. Its pretty much the same price as the porsche brand so before u assume there is a p-car tax try shopping around. The dealers that sell on the internets r very competitive. Just got an interior trim piece from my local dealers online site for a third of a used ebay part.
Funny thing is, I was the Cummins factory trainer now 11 years retired, training the Cummins distributorship Techs and truck dealer techs around the country on Cummins engines and products.
I trained your distributors internationally. I used to go a lot to the cumins engine factory in San Luis Potos� M�xico. I had a lot of insight into engine development at Jmar (mark martins truck fleet). Cummins CEO Tim sol so was on the board at Ashland parent company of Valvoline, James O Brien Ashland CEO was on the board at Cummins. Hell even though I work for Valvoline I helped your distributors specially in Mexico and Brazil sell engines. I was one of the outside people to see the signature 600. Internationally there were issues with B and C engines and we try to help thru proper Ku room and maintenance in Argentina at one point we were dealing with diesel over 1 percent sulfur. I also worked a lot with power gen all over the world.
Yeah I follow the company business wise. I bought below $100 per share. Every time there was issues with engines we were called. Internationally we found a lot of under spec non api oils and bunches of bad fuel, worked a lot with fleet guard too. Years of my life, lot of experiences, over 100 countries visited,
So I really don't get the point of this thread about coolant, and actually don't want to know anything about diesel engines. You own a Porsche. Buy Porsche coolant and mix 50/50 with distilled water. Pour the mix in your coolant system, then go for a drive. I really don't get what all this other crap is about, and frankly, don't care. It is not helping anyone.
Don't worry, you were never really on a subject.
It was just a rambling incoherent mess of half-information about coolant and diesel long haul semi trucks.
Are you one of those bots that pretend to have a conversation based on keywords, but are actually pretty bad at it?
Let me test some keywords and see what we get back:
Coolant, water, pollution, rainbows, unicorn, highway, magic, wizard, spaceship.
I think I figured out enough by seeing that you started this thread with a post that lacked focus and was edited to correct/remove a racial slur, then by viewing your other posts that had more do with all the companies you've worked for and your stock purchases as if that would make your positions more credible. I bought Boralex at $14 and it's around $50. Yeah, I follow the energy industry. Doesn't make me an expert in in wind turbines waterfalls, or an expert investor.
How long have you been here? There are better ways do develop credibility and trust.
