bx2370 antifreeze

[hit440]

I am looking for suggestions on if i can use an aftermarket antifreeze for my bx2370 its a 2015 model

i called two local dealers and they dont even use the kubota brand, they both said to use just the conventional "green" 50/50 antifreeze, however searching on other forums i have found a lot more options that consumers have gone with

I use red ELC in my tractors. Just make sure it's silicate free and safe for all radiators.

Your Owner’s Manual should tell you, but I believe all Kubota’s use ordinary ethylene-glycol antifreeze (Prestone works just fine.)

It just pizzes me off when I try to educate myself about antifreezes.
Visiting the Prestone, Zerex, Shell, and ANY other site will only confuse because they ALL hedge their comments.

They ALL tell the difference between different types (IAT, OAT, HOAT) ...and they ALL warn against mixing them.... and they ALL claim THEIR brand is best...

...then they ALL warn that NOT ALL follow the same color-codes and so that color cannot be relied upon...that the ONLY way to make sure you don’t hurt your engine is to use ONLY what the manufacturer recommends....

...then they ALL say that regardless of what you read anywhere THEIR brand/type/color is BEST for your engine .... and that mixing THEIR brand/type/color is OK, if not downright GOOD for your engine!

But be CAREFUL not to mix different types...is their final word... except THEIR brand can be added to ANY other type.

Zerex G-05 has nitrites for sleeved diesel engines.... but Kubotas don’t sleeve their engines. Prestone claims to be good for diesels...but doesn’t mention nitrites.

The Zerex site states that HOAT is a mix of OAT and IAT and that it contains propylene... but my Ram truck states to use ONLY HOAT and to NEVER use propylene antifreeze.

Prestone claims to be the BEST for ANY and ALL...but fails to state which technology is in their product at all.

Then some know-it-all with an accent demonstrates that adding yellow to pink doesn’t change the color...it’s still PINK... and that is the PROOF of his scientific method... so THERE!

There are a wide variety of coolants that are compatible with your tractor. My personal choice is Zerex G05 HOAT coolant. The majority of coolants are Ethylene Glycol based (including Zerex G05). I chose Zerex G05 for the 5 year interval, but there are plenty of other long life coolants available.
One coolant you should absolutely not use is DexCool.

I agree that the color schemes and manufacturer claims are a quagmire of confusion. Best practice is to thoroughly flush when changing coolant type.

i pulled this from coleman equipment site yesterday Item #70040-0L014
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.

thanks for the replies, yes i saw on some other forums guys using the zerex g05 which incidentally is the same i use im my dodge ram hemi, so that sounds like the way to go maybe, i was just thrown cause its a HOAT technology and wasnt sure if the motor supported that. my local oreilly auto has just the conventional 50/50 green stuff too

Well...THERE YA GO! The Kubota Owner’s Manual specifically recommends ethylene glycol antifreeze...the good ol’ original GREEN stuff....

.... YET.... the original green ethylene glycol antifreezes are IAT...in other words, CONTAIN SILICATES as their primary anti-corrosion additive....

..and now, the “Genuine Kubota” stuff claims to contain “NO silcates... etc THAT CAN CAUSE PROBLEMS....”.

ya the manual really didnt help much to ascertain which other than the kubota brand antifreeze is safe, like you said the convention stuff may contain silicates so i have no clue at this point and i really dont want to pay 50$ for antifreeze thats just ridiculous, i guess as i said in my previous post if everyone says the zerex is safe to use and no one has reported any issues i will just go with that

The product PI sheet states that the "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 application and does not contain any silicate, borate, nitrite, etc that can cause problems in the cooling system. Meets performance requirements for Kubota and other Asian engines."

Looking on the Zerex website VALVOLINE™ ZEREX™ ASIAN VEHICLE GREEN ANTIFREEZE COOLANT the PI states that "Valvoline ZEREX Asian Vehicle (Green) Antifreeze Coolantis a patented* formula designed to meet the specifications of original equipment manufacturers (OEMs) requiring a green, silicate free, hybrid organic acid technology formulation (HOAT). This formula has a service life of up to five years or 150,000 miles. It incorporates premium state-of-the-art phosphated organic acid additive technology in an ethylene glycol base for complete protection of today’s modern cooling system and engine components. ZEREX Asian Vehicle contains no silicates, borates, 2-ethylhexanoic acid (2-EHA), amines or nitrites. It is compatible with premium long-life Asian vehicle coolants, both for service and factory fill. Valvoline recommends ZEREX Asian Vehicle for all late model Asian vehicles requiring a greenHOAT chemistry."

However, the "Valvoline ZEREX Original Green Antifreeze Coolant is a universal ethylene glycol-based formulation suitable for passenger cars, light trucks and heavy-duty vehicles. The formulation is designed for both gasoline and diesel engines and has a service life of up to five years or 100,000 miles. Its patented* low silicate formulation protects all engine cooling system metals from corrosion including aluminum. The ASTM test data shown on this sheet reflects the high-performance corrosion inhibitors package."

Therefore, it appears to me that the Zerex Original and Asian Green Coolants have the same characteristics as the Kubota Genuine Coolant. The difference seems to be that the Original is designated for use in diesel engines/heavy duty vehicles. The dealer I purchased my BX2680 from uses the Zerex Original Green Coolant in their service department.

See this YouTube presentation by Kubota for coolant.

Local dealer told me (at least for my G2160) to simply buy, Toyota pink or Honda blue (essentially the same product different color). So on last coolant change that's what went in there. The color does not dictate the specs. All antifreeze is basically clear. Dyes are added. Nearly 100% of coolants are ethylene glycol based as well. Regardless of being Toyota, Honda, Mopar, Kubota, what have you.

Well, I guess that I will say this again. As you might imagine, Kubota doesn't make antifreeze. They buy it private packaged. Here is the Material Data Safety Sheet for the product that is private labeled for them.

Lmichael makes a great point. Anti-freeze is clear until they add a dye. So .....the color only means something to the company whose name is on the label. It is the specs that matter.
