Can you mix red and yellow antifreeze?

[benny6910]

As the title can I put Newholland red antifreeze in my manitou that has yellow/ green antifreeze in currently. I’m sure dealer said that manitou don’t do the yellow green anymore it’s red. Will I have to drain it all out to be safe and use the red? Any advice welcome. Thanks in advance Ben.

I wouldn’t even have checked; I’d just top up

No, you shouldn't mix different colour antifreeze's.

Look on line like Morris oil or exol lubricant and suchlike and they give recommendations of their product to suit your machines. They may well recommend the same product or a totally different product for them two machines.

Definately not. OAT will react with MEG and go lumpy.

Anti-freeze job seems to have gone crackers this past few years !! Used to be you just put "anti-freeze" in everything.... Now it`s Oats, Beans and Barley-ooh!!!
VERY frustrating trying to make head or tale of what you can put in what -- the label on the container and the tractor handbook can be less helpful than a chocolate fireguard.....
My advice would be speak to a Manitou dealer and use what they suggest (provided they seem to know what they`re doing!).... Using the wrong stuff because someone on here said just bang in what you`ve got could long term prove VERY expensive ...... not a saving of a few quid!!!

I must have been extremely lucky over the years then as I stick John Deere coolgard in everything whether it’s new to the farm or been in here for a while. Cars, mowers, tractors, combine, vintage stuff. If we have run out of that and are desperate there’s usually some universal anti freeze kicking around so that will go in instead. To be honest I didn’t even know there was a difference!

Yes you must have been born lucky! I`m bound to say it`s a damn nuisance that you should use the "right" stuff for each machine, it would be so much simpler if you could just put "antifreeze" in everything or anything. Swapped a couple of tractors recently and what a bloo*y nightmare trying to compare specs on the container to see if the "old" antifreeze will fit the "new" tractor..!!
I think they are just bloo*y awkward so that we feel we`ve got to buy their stuff just to be safe...

asked dealer for universal anti freeze same as he supplied in the past , different brand so he asked the question with his supplier , universal was just a different dye added to anti freeze and sold as universal , you can add red to blue but you loose the long life properties of the red anti freeze . add some red and blue in a bottle and put it on a shelf and tell us how you get on . me i buy red now for all the price difference why would you bother with blue

Unless they're labeled propylene glycol, they're all ethylene glycol, just a different corrosion inhibitor package. In the old days it was nitrites in heavy duty, silicates in automotive, then OAT, and now it's moving back to hybrids of OAT and the old additives, so they can't be that bad to mix. You can look up a chart to try to figure out what you've got and what should mix with it. They mostly say their own brand can mix with anybody else's, but you can't mix anybody else's with theirs. If it's all too complicated, add distilled water if you started with 50/50 and you test it with a hygrometer before winter.

Mixing colours isn’t the issue it’s the active ingredient that’s the problem

 

[benny6910]

Thanks everyone it’s as clear as mud to me so I shall probably have to drain the lot out and put red in as I’m sure dealer said manitou don’t do the green yellow anymore.

 

[Moors Lad]

Thanks everyone it’s as clear as mud to me

Yes, that`s about it in my eyes too...

 

[DrWazzock]

That’s why I’ve gone back to 50% ethylene glycol (bog standard blue antifreeze) in everything.
Don’t get me started on varieties of ATF fluid ahd brake fluids. What a clusterfeck.

 

[TelesnaAg]

Yes you you can, depending on glycol type and additives, colour isna dye...means zero.

In mining i will usually get the oil manufacture lab doctor to run a test and give me a compatibility report and recommendation.

If roughing it...make sure glycols are the same.

Label will state what is used.

They both just say ethylene glycol so I’m guessing they should be ok will try some in a bucket and see.

Yes, glycol matches, its the additive pack that needs testing so a bucket test is worth it for sure.

The mix rate if each product is another consideration, are they complete mixes or concentrates?

They are both pre mixed so it shouldn’t be much of a issue

Bucket test is all you can do.

How large is the system?? To drain and stay with one coolant or is it goingbin s clunker??

When i get chemist to check its normally because the $$$ of engines its going in is in the tens of millions.
