Does Peak OET Asian Red have 2EHA now?

[SC Maintenance]

Since when does North America care what Europe does?

We clearly don't but auto OEM's like to run on global standards whenever possible.

If you do care 2-EHA is also a very toxic substance. Its fatal to fish - leaking cars end up in the water supply. Your not supposed to touch the stuff, which is hard if you have to repair anything cooling system related. Yes, obviously wear nitrile gloves but still.

Ethylene glyccol is toxic. Motor oil is carcinogenic.
When the USA EPA bans 2EHA let us know. Until then I’m not going to worry about it. I guess to each his own.

Canada is working on it https://www.canada.ca/en/environmen...hexanoic-acid-2-ethyl-2-ethylhexyl-ester.html

Reochem owned prestone is the only one that uses it. Careful what you wish for.

Haha. Eight year old document addressing foot lotion and makeup. Don’t drink this stuff!

FWIW, I have Prestone Cor-Guard AMAM coolant in a Toyota Sienna I had to reseal the valley plate(thermostat housing) for several years, plenty of road trips - no coolant leak or loss. I did use Toyota’s super duper expensive RTV to reseal the valley plate.

Someone posted a UCA on factory Toyota pink from a Japanese production car(GX460, assembled at the Tahara plant), and it has <6000ppm of 2-EHA but plenty of sebacate. Both are plasticizers with effects on silicone(RTV) - and valley plates love to leak on the UR-family V8s but it also happens on MZ-family V6s.

When I owned my Toyota Tacoma 3.4L (oe LL red), I ran long time bitog favorite (my observation) no 2eha Peak Global Lifetime Concentrate. Never missed a beat, i.e., no issues. In addition to PGL, Peak now makes newer no 2eha Titanium AF.

As for an earlier claim of SLL pink now using 2eha, beyond some nebulous hearsay reference to it's use, still no "reliable citing" as desired. Again, sebacate is not the noted 2eha. So for me the SLL 2eha "reliable citing" remains, ......

The no-2eha Peak 'Titanium' is currently on sale at O'Reillys...$13.99 for the 50/50 and $16.99 for the concentrate. Sale ends 6/23/26.
PS: I've had no-2eha Peak Global Lifetime in my 2008 Corolla for years without issues. I used the last of my stash last Fall and will probably go with Titanium next if I still have the Corolla in 4 or 5 years.

Last year I put peak asian red in our 2004 rx330 during a major service. Im now replacing the radiator and will need to add coolant. I'm not entirely sure if the version I bought in late July was pre - 2eha changeover - the sds update in May I think. Regardless because this engine has the notorious rtv valley coolant cover (that I've repaired), I'm thinking of filling her up with zerex red and not using the now 2eha peak.

Zerex red : phosphated hoat or p-hoat
Peak red: poat

Will these play move in the sandbox together if I don't fully flush the block and heater core and just refill the drained peak red with zerex red?

Zerex Asian blue.

Zerex Asian blue.

If you're replying to me, it's my understanding that zerex Asian blue and red are the same thing with different dyes

Also I read through other bitog posts and it's suggested that mixing coolants with silicates and coolants that do not contain silicates is the primary concern for bad mixing? The zerex red and peak red are both silicate free. I haven't found ANY posts that recommend NOT mixing peak & zerex red, but have found a handful with posters stating mixing the asian red formulas from zerex and peak as being perfectly fine.

(Edit - I still have the container from the peak red fill, and it was before they added 2-EHA, sds #115019)

In theory, they should mix. FWIW, I resealed a Sienna with the same engine, used Toyota’s super duper 1282B RTV. Filled it up with Prestone Cor-Guard. No leaks, this was done 5 years ago.

I drove to a few autozones today, no old stock to be found. Only 2eha available. Why did they have to mess with it!?!?

Grabbed some Zerex red at O'Reilly.
