Cavitation is an issue with sleeved engines and only the big ones are sleeved. I only have experience and common knowledge to go on but ethylene glycol should be no problem for a non sleeved engine assuming manufacturer recommendation and change intervals followed.

I have one machine that specifies using SCA additive antifreeze. I started using the Peak Fleet Charge concentrate in all my diesels just for consistency. It requires mixing with 50% distilled water but claims the SCA additives are exact.
They don't mention Kubota in their compatibility specs though.

We need to figure out what's what with Kubota and anti-freeze requirements. Is it ethylene glycol only with a two year change cycle or is the 5 yr extended interval diesel anti-freeze good to go? And if so, what is the change interval and why?
Someone must know what's OK and what isn't. It's like the great Kubota 15W40 oil mystery that dragged out for years before they gave the all clear. Same thing with synthetic oil since Kubota was absent on commentary.

Kubota tractor just purchased this July clearly states ethylene glycol based long life coolants 2 year change cycle. No advanced specifications and no Kubota coolant only recommendation.
Why no extended time period is simply a CYA measure that costs them nothing. The extended life coolants are being pushed by the Green movement as being less polluting. Since Kubota also likes pushing a Green image just a matter of time before they are pressured by Green groups and manuals are changed.

I decided to do what the owner's manual suggested.
Flushed, and replaced antifreeze as per specs.
Well later on I popped the rad cap to check levels etc. and the cap came apart in my hands.
The innards were eaten away by corrosion!.
Hope my engine is doing better.
Replaced with an auto parts unit and so far so good.

That's an extremely broad statement that would cover a huge range of engines made in multiple countries and by differing manufactures. I can't find any Kubota literature stating this recommendation. If this is an issue certainly It would be in the manual. One thing I've found researching oils. You can't believe information posted on well known dealer sites such as Coleman's. They have oil information that conflicts with the Kubota factory web site.
