Antifreeze Prestone or OEM Toyota

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

Toyota coolant, the red / pink stuff is some of the best coolant available.

Just use toyota long life coolant je bro. Applicable to all car but buy the original one at toyota SC. Many prefered this coolant since it is good to engine cooling system

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.

I currently just drove 20hrs down south to Florida and the engine level has stayed slightly below half level as it should be the entire trip. Still in Florida driving around the intense heat and sun and everything is still going well.

Prestone European coolant...premixed

No issues.for.me

Prestone coolant. That's extremely good.

Mods: None, staying showroom stock. TCL Buyers Guide Negatives / future ownership issues: A) Valley Plate coolant leak: Look for pink crystals (dried coolant) underside of engine near where transmission meets up w engine. Also check upper radiator hose where it connects to radiator. Workaround: 50k/5 year coolant maintenance.

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.
