Is Zerex GO5 compatible with Kubota Coolant

Is Zerex GO5 Coolant compatible with Kubota Coolant?

 

[RjCorazza]

It's never a good idea to mix different coolant types. If you want to use Zerex G05, I would drain and flush the standard Kubota coolant.
I run G05 coolant in all of my Kubota machines, and F250.

Kubota coolant is the plain old green ethylene glycol.
Just like the stuff used in automobiles until 1995-2002.
Might need to go to the dealer,or an auto parts store to find it.
I used it myself,but many prefer to upgrade coolant for various reasons.
Good Luck!

Spank me if I'm wrong but early Kubota's were conventional green ethylene glycol but later ones are Global orange Both mine are green. I change mine every 2 years after a flush with Dawn and water.

I do know one thing and that is, if you add extended life orange to conventional green, bad things happen in a cooling system.

2020 M5660 has the old fashioned green ethylene glycol stuff from the factory.

Some brands are compatible. I switched mine to Peak Global coolant. It can be mixed with other types of coolant and is good for 12,000 (I think?) hours with just regular testing with their test strips.

It does not require a flush without filling either. As long as their 70% of it in the system, it is as good as having 100%.

I just looked in my L2501 Operator's manual out of curiosity. Other than a statement on page 100 to "use ethylene glycol (EG) for this engine," and I didn't find any ANSI spec for coolant. Seems odd to me, because all of my cars list the ANSI spec which can be used to identify compatible coolants.

Kubota makes a "extended life" coolant. It is a Ethlene-Glycol based phosphate coolant.

My tractor is 2017 and came with the green stuff. Same as you would get at the auto parts store.

I decided to try the upgrade (extended life coolant) next month. I went to my dealer to buy some, but they didn't carry it. Said it cost more that the green. I got it at another dealer. Interesting, the extended cost $21 and is concentrate, makes 2 gal. - their green stuff is premix and cost $14. The exended life is cheaper.

I would never use the orange stuff in the tractor. There is a reason it is a different color.

The extended life description. But you still need to change it at 2 yrs.
Kubota Genuine Coolant is a premium Ethylene Glycol-based phosphate coolant certified for Kubota Engines. Its formula consists of unique characteristics to meet Asian vehicle applications and does not contain any silicate, borate, nitrite, etc that can cause problems in the cooling system.

Probably doesn't make much difference. But if I trust buying a brand of tractor, then I probably should trust their recommendations regarding fluids.

I did change to Rotella T6, but only after talking with the Kubota Service department. They said "can't get any better oil than T6".

Good luck finding T6 right now. Unobtainium around here.
