Does Peak OET Asian Red have 2EHA now?

I went to AutoZone today to get a jug of the Peak Asian Red for the 4Runner, but noticed the ingredients are different from the jug I got a few years ago. First picture is the old jug and the second picture was the one on the shelf at AutoZone today.

That’s the Dexcool 2EHA stuff that the Toyota coolants aren’t supposed to have right?

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO :poop:o_O(n):mad:

At least Zerex Asian is still available, and so is Pentofrost A1 (red concentrate) and A4 (pink 50/50 premix)

Too bad Peak started using 2-EHA in their Asian coolant. At least Peak still has their Titanium and Global Lifetime without it.

Thanks I went with 2 gallons of the Zerex Asian concentrate from Valvoline's website. They had free shipping and a 15% off coupon WELCOME15 and each gallon came out to $17.76 before tax. Peak Titanium was 19.99 on Amazon and the OET was 22.99 at Autozone, so the savings covered the 2 gallons of distilled water.
 
The formula change was covered in another recent thread, but I want to mention this is a step forward, not the opposite. 2EHA is an absolutely superb corrosion inhibitor and is perfectly fine in Asian vehicles. Notice the service life of the old formula was 5 year/150k? Take a look at it now, 15 year/400k. How can this be? 2EHA, thank you very much.

Yep it does. I called Peak Tech line a while back to confirm some previous info posted on this subforum and was informed they changed the formula. Rep I spoke with at first didn't think so, I called him back and he confirmed. Now, I've crossed off Peak OET Asian from 'my' recommendation list of aftermarket AFs for Asian vehicles. Another unfortunate result, it was one of the very few 'true' Asian Phoats available as a concentrate, at AZ. I would imagine if one looks closely there's still some of the previous no 2eha OET formula jugs out there. As noted, readily available Zerex Asian AF still maintains it's true Asian Phoat formula with no 2eha. In the AMM AF's with no 2eha, Peak sells newer Titanium, and longtime AF, Peak Global Lifetime.
 
2-EHA was never designed for asian vehicles and they were not designed for it. It takes a very long time to actually work - unlike a true HOAT or PHOAT and it can deteriorate plastics and gaskets of certain types. Will it in your car - who is to say, no one at the OEM ever figured you would pour it in 🤷‍♂️

I avoid it like the plague.

Now if your car was designed for 2EHA / dexcool - its fine.
 
Pretty sure on here someone posted an analysis of Toyota oem, dealer purchased, super long life coolant which contains 2-eha
 
I'd like to see a reliable citing for claim SLL pink now uses 2eha. I've never seen it posted here or elsewhere. SLL pink does use sebacate as inhibitor which some equate with 2 eha, but is not 2eha. Afaik, only current Asian OEM AF that has gone to dark side with "2eha", Subaru. That said, I've read at least one Suby owner/member here say they will continue to use no 2eha Zerex Asian, rather than Subaru AF. In any case, until I see citing for the 2eha claim, stick with SLL pink still a no 2eha Asian Phoat AF.

2-EHA is required to be listed in the SDS. Do you have the SDS?

2-EHA is banned for coolant in Europe and has been for quite a while. Which would mean it wouldn't be able to be a global coolant.

Toyota has never used an OAT for factory fill that I am aware. The old red was phosphates I believe.

If you have the data please share.

At the very minimum, 2-EHA *requires* a pressurized coolant tank, or else air will get in and make it sludge. And of course, the rest of the gaskets and materials used have to be compatible as well.

Remember, just because a car was filled with Deathcool from the factory doesn't mean it was designed for 2EHA/Deathcool :sneaky:

Yes. As we found out from GM they spec'd it but failed to design for it. :ROFLMAO:

My only GM however was a 1996 Olds with 3.1. It had no problems. Was a great car actually. I had to let it go in 2008 for a move - 12 years? It ran fine still, I just couldn't move 4 cars where I was going.

if it’s banned in Europe then why was my BMW and 2008 MB specified for G-48, and, all my classic Mercedes cars back specified for it?

It won’t necessarily sludge. My 98 S-10 that I’ve owned since new still runs Dex. I did replace the manifold gasket though……




Doesn’t Toyota still sell a red concentrate?

The red I believe is a phosphate, per the thread you already quoted.

If you have the SDS it will list 2-EHA if that is what it has in it.

My 96 Olds had Dex and had no problems. I would run Dex in something that was originally spec'd for it if needed. However I still think there are superior products out there.

As I posted before, the whole point of Dex was so GM could extended service intervals which is what people want. 2-EHA takes a long time to work. This and other parts of it cause other problems. If your the type that doesn't mind changing coolant every 4 or 5 years then there is no good reason I can think of to use Dex. To each there own.

Here is from Info on Prestone Asian Blue MAX with 2EHA, complete with it SDS showing 2EHA. It agood for ALL Acura and Honda vehicles and starting in 2009, all Nissan, Infiniti and Subaru. It’s good for 15 years and completely re-defines the coolant industry. Mods, I’m posting some screen shots from Prestone to clarify the situation.

They banned it less than 2 years ago

Yeah, but it's $35/gallon :sneaky:

Zerex Asian Red concentrate is $20
 
......Doesn’t Toyota still sell a red concentrate?
They do, but it's the older Phoat technology with a 2year/30k mile recommended service interval. Toyota superseded it on 'newer vehicles' with longer service interval SLL pink. Toyota has said SLL pink is backward compatible with red. Neither AF uses 2eha as inhibitor. Nissan had a similar shorter service interval green tint AF that they completely superseded with current blue LL AF

As for the now very extensive 'promotional imo' material posted for Prestone Max "Asian", no surprise it uses 2eha. Based on Prestone history with their "Asian labeled" AF, they have long used 2eha. That includes years before Subaru relatively recently became the only Asian OEM to use it. Since the promotional material posted, Prestone Max, another aftermarket Asian labeled AF not on my recommended list for Asian vehicles.

Prestone has always said there 2-EHA OAT mixes with everything even with there regular stuff. It will mix.

If your 150K mile 12 year old car blows a gasket or the pump impeller rusts up there floor full of lawyers will laugh at you.

Feel free to use what you want. I know Nissan for sure has never spec'd 2-EHA. They went from an IAT to 2 differnt PHOAT's. Toyota I know less but I am pretty sure the pink and red have never had 2-EHA - before that I do not know. Other Asian cars - no idea.

I am unsure how Prestone / Reochem would be familiar with every material Toyota / Nissan used - but Toyota and Nissan do.

To each there own.
