What antifreeze do I use.

[Goreef]

I have a 6530 and all of the recommended coolants in the manual are not available here in central Texas. I have looked in the stores but all of the heavy duty diesel coolants are some other color than green. Any input would be greatly appreciated.

Green is about the most common antifreeze out there so I can't imagine youre not being able to find it. Not that it's the best just the most common. If you change types be sure to flush out the old stuff well.

What is your coolant spec, as listed in the manual ? What does your dealer stock ?

Don't confuse colour with functionality. Green up here is old-school 2 year 50,000 mile (road vehicles obviously) regular antifreeze - if you use that in a diesel that requires cavitation corrosion protection, you will shorten its life.

Unless Mahindra has some very unique requirements, I'd be surprised if any of the modern Extended Life Coolants (ex. Rotella, Delo, CAT) that are diesel rated would be a bad choice, regardless of colour.

To be clear though, I know nothing about Mahindra's specific coolant specs....

I ATTACHED ALL THE COOLING INFO I COULD FIND, I KNOW IN ALL OTHER TRACTORS I HAVE LOOKED UP ITS E.G COOLANT (GREEN)

Use Tractor supply "Fleet Guard". It has the SCA pre-charge in it. Silicone control is needed in diesel engines. Regular antifreeze will work but is not the best in the long run. You only change this out every couple of years so it does not make sense to just buy the generic antifreeze to save $15 or$20 bucks.

Make very, very sure what you are putting in is exactly right for your tractor!!!! There are several types of engines mahindra has used. The most sensitive will be the mRCDE engines in the 40 and 50 hP tier 4 engines. This engine cannot use the old green at all. It has silicates for corrosion protection. Silicates will pull pinholes in a wet sleeve engine. Silicates will precipitate and glaze (insulate) the surfaces on the egr cooler, which will send it into permanent limp mode requiring replacement egr cooler and egr radiator etc... HOAT comes in different types. It may be greenish, yellow orange and maybe even blue. Besides the different colors, some use phosphates, nitrates or other chemicals in addition to the organic acid agents which themselves come in different formulas. Some organic acids (especially the three that are in DexCool{Pink}) will destroy plastic or silicone components of gaskets if not compatible.
So, be very careful not to use the wrong one. The wrong choice (consider too that your dealer might not even use the right one if he sells different brands and only uses one coolant for all brands of tractors and brands of engines found within brands of tractors) could require a complete engine rebuild in a short time. The shock wave(bang) on the cylinder sleves causes silicates (WHICH IS IN ALL TAP WATER TOO) and phosphates that stuck to the out side of the sleeve to vibrate at a force which will propel the scale off. Sounds great, but it pulls metal with it and makes pits that go all the way through the wall in no time!
So, If they require HOAT, not all hoat's are safe. If they require OAT, not all OAT's are safe. Ask many questions and don't just depend on the counter guy who says "this one is universal".

I looked at some of that while i was there but when i saw that the color was a pinkish purple i thought it wouldnt work because i have the green stuff in it now

 

[Goreef]

Thanks for the reply. im going to see if my dealer sells a mahindra brand coolant so i know im putting the right stuff in

 

[burzynsr]

Welcome aboard, I also purchased from J5 and have been very pleased also. You will see their posts here. Look for "Navasot".

In the for what it's worth category...
My New Holland Workmaster 50 utilizes an EGR Valve and Catalytic Converter...
The owners manual calls for Ethylene Glycol...
I've got to look and see but I don't recall the addition of SCA's to that information...
It looks green to me...
I don't know the specific differences between the mRCDE engines in the Mahindra non DPF engines and the FPT Workmaster non DPF engines...
I would assume that they are the same...

HOAT'S, OAT'S, SCA'S, IDK?

All my vehicles, especially diesel vehicles, have CAT EC-1 rated ELC coolant.

I would like someone like Dave from Dave's Tractors or "Mahindra Don" to tell me exactly what the "factory fill" is for a mrcde engine. Not just what class or color. Exactly what is used and is to be used. The service manual just says low silicate. Are they talking HOAT, OAT, Eurospec HOAT, etc... Much detail is needed. Aisian antifreeze is always low silicate, but when you go to buy the products often mentioned; they don't give much specs. I don't go by what the parts guy says is right after he scratches his head. I don't go for what the dealer who works on many brands and ages of tractors when he says: "this is what we use in everything". That just doesn;'t cut it. You won't know a problem until you have very expensive problems.

 

[3550hst]

Dave, Don are you reading this?

 

[Goreef]

yeah im like you. i would like for them to break it down for us.

HOAT'S, OAT'S, SCA'S, IDK?

Problem. History. Present solution.

Cavitation corrosion in wet-sleeve diesels is an old problem. SCA/DCA were older classes of chemicals that were added to basic antifreeze to control and solve cavitation corrosion problems - they get depleted, and need to be replaced. My road going diesel has a coolant filter - you can buy filters from Fleetguard loaded with SCA/DCA, or you can add it manually. Test strips are available to analyze SCA/DCA.

Modern organic acid coolants were developed to provide long-life, and control cavitation corrosion directly.

While there are some nuances to Organic Acid coolants that I still need to understand better, the bottom line is simple:

If you have a diesel at risk for cavitatation corrosion, most of the modern fleet organic acid long life variants provide way more protection out of the bottle, than pouring in 1960's era gasoline engine coolant and neglecting to add SCA/DCA.

Best place to start is understanding a clearly communicated Manufacturer Spec.

IDK may be just I Don't Know. (?).

Clearly Communicating proprietary formulations by chemical manufacturers is a rare event. We never get to talk to the people who know aluminum, gasket, hose, brass, solder, brazed plate heat exchanger (used in oil coolers), sleeve cavitation, protection depletion, product interaction, egr cooler destruction, precipitation, gelling,etc...
I have a 743 Bobcat that I lovingly rebuilt. Always used their hydraulic fluid. They did not inform the public that they took compounds out that protect your reduction gear and wheel seals. Still they say don't use Gl-90 in the chain case because it wil eat brass. Since they took out the protectants out of their product, I put in a 50% mixture GL-90 and I will replace my brake pucks easily when they wear out (which they haven't). The price of ten gallons of their stuff is 160 bucks. Just another case of a manufacturer's mindeset of programmed obselescense at our expense. Just another example of denying the customer crucial information and good advice.

I have a 2538 and my manual does not give any specs for what type of antifreeze to use. It just says to use at least a 50% ratio of antifreeze. That don't help much. I know it has a wet sleeve engine even though the book says dry cylinder sleeve, everything on the internet says the Mcrd engines are wet sleeve. so what antifreeze would you use in this tractor.

I used Delo last time around. Time moves on.... more than one flavour of Delo ELC exists now.

Looks like the main issue is nitrites. CAT EC-1 appears to spec nitrites, other manufacturers don't want it.

The nitrite requirement with certain OEMs may be for specific corrosion protection requirements. I don't know enough about nitrite performance to publicly guess on the downside of having it present, but not needing it.

Somebody needs to beat some answers out of Mahindra. Releasing equipment to the market w/o critical fluid specs available is at best, negligent. IMO.

Somewhere within Chevron (or Shell, CAT.....) there will be a database of what equipment specs what. Might be worth an email to these chemical producers - I'd start by saying Mahindra won't supply the info.
