Antifreeze

[TheOldHokie]

If hard water is an issue which l don't believe is a problem. Having spent twenty years in the automotive industry ten of which as a mechanic, no one l knew used water other than what came out of a hose to fill a radiator. If hard water is a concern, use the water out of a dehumidifier. Sane goes for batteries. Tap water out of hose was used to fill batteries. I'm sure it still is on serviceable batteries. Most homes have a softener system anyway. Some have mineral filters too. The issue years ago was the acid from the old anti freeze ate up seals, water pumps, hoses, and radiators, heater core. Re core of radiators was common business back in the day.

Use of hard water is definitely a problem - tons of very real and reliable research to document that.

Here is another clue as to what Kubota is selling. Its a phosphated HOAT - e..g. PHOAT. Its silicate, borate, and nitrite free and very typical of Asian OEMS..

PHOAT — The difference between HOAT and PHOAT is the primary additive component, which uses phosphates rather than silicate. Honda, Toyota, Kia, Hyundai, Subaru, and Nissan typically recommend this type of coolant. Many of the aftermarket coolant manufacturers will specify “For Asian Vehicles” on the container and it is often red or blue in color.

Dan, When I went to my dealership looking for the Kubota anti freeze, I went to the counter told them I wanted a gallon of anti freeze. They handed me Peak extended use 50/50..They said it's what they use in all their machines both new and for service. They have been in business for over thirty years.. They said it's the same stuff as the Kubota branded anti freeze. I don't think Kubota makes it's anti freeze or oils either. They have vendors supply their products with the Kubota label on them.. I don't know who but I think it wouldn't be to hard to find.

Which then adds salt. And as a professional tech even WAY back in the 60s we did NOT use tap water for batteries in the shop. We used distilled water only. Yes back then we used tap water BUT it was from Lake Michigan which is naturally a pretty soft water and does not leave deposits and such. Modern engines also are not so tolerant as those of the vehicles I began working on. Going back to model years of late 40s and all the way to then present times. (Yeah I even worked on one Caddy with hydraulic power windows). The safest way to treat the cooling system is use good ol distilled water.
As for the Kubota stuff being a HOAT. Good point. Likely very similar to Toyota pink and Honda blue.

I am not advocating for Kubota branded coolant. I was just trying to shed some light on what's in the jug. Any of the extended life formulations are going to be fine. Even if I could find one I would not use an old school IAT coolant in anything I own including the 80 year old Ford tractors.

Dan, I agree. I don't even know if the old school coolant is still available. I use water out of our dehumidifier in my radiators and batteries.

By your statement you've never had the pleasure of cleaning out a cooling system thats full of mineral deposits or having to explain to a customer that his 2 year old radiator is shot because of his poor choice to use his well water and mix his antifreeze instead of buying premixed antifreeze or distilled water.

Haha!!! I grew up on well water. Like I said, I live in the southeast, and, for all intents and purposes, live on a limestone mountain. Filtration and cleaning the water supply has been a way of life, for my own 'filtration system' as well as all of my equipment.
If you have been around long enough, you cannot deny the design of today's radiators (to lower production costs) have made them more susceptible to clogging. Smaller, more dispersed fins, thinner jackets, and plastic make the operational margin of error much slimmer. Naturally, this forces the necessity for good maintenance.
That said, aside from a failure requiring the system to be drained, why would any 2-year old machine need the coolant system drained?

I use 2 of these systems: Rhino Well Water with UV | Aquasana Whole House Filter System One at the house and one at the main barn that is distributed throughout. Both are modified to have dual filters so one can be offline for service without interruption. I am also an EE, so for fun and practical purpose, I have flowmeters on both lines that alert my phone via a self-made app when there is more than a 5 psi drop on the lines.

EE pay must not be what it used to be. Distilled water costs less than a buck per gallon and it don't need a filter or monitoring system.

Sooo, you buy all bottled water for your home? Drinking, cleaning, washing, animals, etc...? Smart, real smart. Not to mention the plastic waste you are creating. Smart, real smart.

FWIW, I am north of 250k annually, not including bonus which can be another 50k+. Not that it has anything to do with... anything.
EE pay has increased by double digits percentages year over year for over 2 decades. More than that if you are well versed in the control side of things. Not many software guys can say that today. Bots, self-learning software, and cheaper overseas staff has seen to that.

Actually I drink, shower, and wash clothes and dishes with well water. It goes through a $15 paper filter to take the sand out and tastes pretty good. I purchase a couple gallons of distilled water each year for radiators. Glad to hear you are doing well financially.

Ahhh, a reminder of why the “ignore” button is there.

 

[GeoHorn]

I have never heard of 'special diesel antifreeze'..

and you think that’s a definitive thing, because you’ve never heard of something…do you…?

I am glad to hear the water is not so hard up north.

Not at all. I was just saying I have never heard of it.

 

[Dave Ogren]

It was a smart move. Believe me. Now, shootings all over, thefts, car jackings and that's in the GOOD areas! Even here in Cherry Valley.

I had a farm on Cherry Valley Road and Bloods Point. I hope it gets better for you, Stay Safe.

Thanks. but it's now why I am VERY watchful and carry

Well, I suggest you investigate the anti-freeze requirements of sleeved-engine diesels if you have any curiosity toward it.

Funny you say that. I asked my BIL who has driven and worked on trucks and equipment all his life. He has small trucking company now. Says all he has ever used in his Freightliners and Peterbuilt's is the green stuff. I know one of his trucks was in the shop last year for a minor overhaul and has over 700k.
I guess it is working just fine.

 

[lugbolt]

well I have seen oil wars.

First time I've seen an antifreeze war.

awesome.

Bicker about anything and everything?

Half the time the bickering ends up confusing the OP, and deviates away from the original subject at hand. Such as (but not limited to) how much one's income is, as if that makes any difference in the subject at hand. I don't care if you're a multi billionaire, if ya ain't got anything better to add to the post, just don't add it.

 

[jyoutz]

Use what your owners manual specifies. Cost is minimal because you don’t charge coolant often.

Just for fun, Kubotas' antifreeze is "green stuff".
