Recommended Green Coolant

[alaskacruiser]

Posting this in its own thread to get some exposure:

With all the recent talk about coolant and red vs. green, can someone tell me what brand AND type of green coolant is safe to use? I know not to use the Dexcool / GL-5 stuff, but not what brand/type specifically is recommended if you're switching to green? I can't find Prestone "Original Green" or "Low-Tox" anywhere, only the Gl5 stuff. Same for Zerex. Will Peak Green work ok?

The Texaco Green, in the black bottle is like the old Prestone formulation that you add you DI water too. It has worked great in my vehicles. Flush system well...

Peak. The new Prestone has 2-EHA(same stuff is in Dexcool), thats the stuff in particular you want to avoid, its a plastisizer and will soften seals.
Raventai posted a really good link just recently that pretty much stated that Japanese makers won't use anything with 2-EHA. Honda was actually upset that the new motor they made for that Saturn Vue, Saturn put Dexcool in it. I ran the new Prestone for a couple of months until reading that article, then I went out and found something without 2-EHA, Peak Long Life. I'm sure there are others that are fine as well.

Here is the link from Raven http://www.motor.com/MAGAZINE/Pdf/082004_04.pdf

I was very dismayed to read that the Prestone Extended Life I installed a week ago is in fact DexCool. It does NOT say this ANYWHERE on the bottle or in the Prestone literature, to the best of my knowledge.

Out it comes, ASAP.

I have also been running it in my KTM and that worries me too.
Damn.
