Antifreeze Pentosin or Prestone

I've only ever used Prestone which works great and has never been an issue.

I use prestones all weather,Great stuff

I’ve used Pentosin Pentofrost NF, it’s the same as OEM

But for the love of god use the blue stuff. Preferably the correct brand but I couldn't find any in my hick-ass town so I used Prestone and I haven't noticed any ill effects

Use pentosin

After that, you can run generally whatever universal coolant you'd like. I do a universal Prestone and have no cooling problems. I live at the beach and drive my stage 2 Jetta 2.5L pretty hard.

I bought prestone Max concentrate for all vehicles. The yellow stuff. I also looked at the technical data sheets on the product. Happy to report this thing runs cooler than it ever has and I live in Phoenix arizona.

Prestone European coolant...premixed

No issues.for.me

Prestone does work, but Toyota uses RTV to seal the coolant passages between timing cover/thermostat housing and engine block. Prestone uses 2-EHA which has been shown to be aggressive on silicone, however it’s not uncommon to see leaks with the OE coolant that uses sebacic acid which is also a plasticizer. That said, I have a Sienna and LS430 that’s filled with Prestone, no coolant leaks… yet.

Do not use Prestone 50/50. It is technically compatible, but it is a different formulation. Using Prestone 50/50 will shorten your service intervals to 36,000 miles. Beyond 36,000 miles you will cause damage to occur to the seals.
