Default HOAT Antifreeze - 06-23-2009 , 09:16 AM






Many newer Chryslers now use this HOAT antifreeze.

Peak has an antifreeze that is supposed to be able to top off HOAT, or
any other kind.

If this true, or will it turn out to be like Chrysler transmission
fluid, in that you have to stay only with that kind, and it cannot be
mixed?

Thanks,

KM

As long as you do NOT use DexCool (which contains gasket-destroying
2-EHA) or any similar product then you'll be fine. Heck, you can even
run conventional silicate antifreeze in a Ford or Chrysler if you change
it every 2 years instead of following the extended change schedule (I
wouldn't do this until out of warranty, though). GM and their stupidly
standing by DexCool is the ONLY disaster in the coolant marketplace
right now. DexCool should be labeled "poison to engines, even many of
those made by GM."

But its pretty much a moot point- HOAT antifreeze is gradually becoming
the single most available formula. Zerex G-05 is in every parts store,
as is Peak Global Lifetime which, IIRC, is their HOAT compatible brand.
Motorcraft G-05 is also widely distributed, and even Mopar's own G-05
brand has a fairly wide distribution beyond Chrysler dealerships.

Thank you. This is exactly the info that I was looking for. I was
wondering what cooling system materials had changed that now require
this HOAT antifreeze.
It sounds like nothing.

HOAT just provides a longer change interval.

Your're right about DexCool. It looks like there are still many
pending suits involving it.

Steve - Have you heard or read much on the Prestone All Makes All
Models? I put it in my wife's Buick about 4 years ago and have had no
problems (although it did spring an intake gasket leak last Fall, but I
attribute that to it being a Buick, not the All Makes All Models).

Been away a while.... sorry for the delay

IIRC, Prestone's "all makes all models" stuff *does* contain 2EHA which
is the suspect ingredient in DexCool. I often hear people call Prestone
"Dex Clone." I wouldn't use it in anything, which is a shame because
Prestone used to be a brand I trusted.

Just so we understand each other: Prestone Extended Life™ *is* DexCool™.
Prestone's All Makes All Models is a different product (meaning
different packaging/different labeling) than Prestone's Extended Life.
Are you sure you're not confusing the two.

What you're saying could be true for both Extended Life and All Makes
All Models. I realize that companies can do really stupid things, but I
find it hard to believe that they could be stupid enough to, years after
the problems with GM DexCool™/Prestone Extended Life™ became so obvious,
introduce a *second* product with the same problem. I always pictured
All Makes All Models as Prestone's way of gracefully diverting people
away from Extended Life/DexCool. Again - I could be wrong - maybe they
*are* that stupid.

I'm just asking you to double check that what your saying is true of All
Makes All Models and that that's not some fact that you read about
Extended Life and are applying to All Makes All Models because you
didn't realize that the two aren't the same product.

I'm sure I'm not confusing the two, but I'm not 100% positive that "All
Makes All Models" really does contain 2EHA. There was a thread on the
coolants page of Bobistheoilguy a while back where several people pored
over the MSDS for Prestone AMAM and concluded that it very likely did
contain 2EHA. Their advice, and I agree, was "since Prestone won't tell
you directly, since there is reasonable evidence that it does contain
2EHA, since you can be sure that Zerex G-05 does NOT contain 2EHA, and
since the consequences are big if AMAM does have 2-EHA... don't risk it."

I find that only a little harder to believe than the fact that GM is
still pushing DexCool after all their own troubles. I'm sure it did
nothing to help their quality reputation or otherwise save them money in
the past decade, yet they still cling to it as if there were no alternative.
