The coolelf auto supra 37 isn't available in the US.  Probably didn't want to bother getting regulation approval OR they just don't have a market here?  BTW do note that this is a silicate and phosphate free coolant.   The green stuff you used are full of silicate, phosphate, borate.  I think the IAT (green coolants) are an alkaline solution with a higher pH and the coolelf (pink) is a lower pH.   Anyway it mostly affects the water seals so if you were to see a failure, you'll see it in a few thousand miles or more.  Heck you may never see a failure until you remove the water pump and maybe the seals will fall apart if disturbed but other wise fine.

What is so different about European vehicles that they cannot tolerate the silicate, phosphate & borate yet American cars have no such issue with any of it?

I would think if it is not approved here, I would not be able to order it, which I just did, with no problem.  I would think there would be a market if it were really necessary. There are many European vehicles here, so I wonder what most of those use if they ever change the coolant.

FWIW, I would have ordered the pink stuff before the coolant change if I knew I could buy the exact stuff on Amazon.

However, page 21 of my 2020 Esse Esse 9 Service Manual says use  "50% water-50% glycol" in the fluids table and that is what the green stuff is that I put in there.  It says nothing about silicate, phosphate & borate.
