Antifreeze PEAK or Prestone

Ive been using peak for a while across a 2016 jetta when i owned it and now in my 2021 tiguan. Works fine

Had good luck with their older Asian green, Toyota pink, and Newer Asian Blue in my son's Subaru.

I have some Peak "original equipment technology" for European vehicles, "violet." It is pre-diluted. It seemed to immediately blend right in, if that means anything.

Find the peak brand equivalent. That's what I use for 2021 RH Model. Make sure specifications match. Properly flush your coolant system before implementing and properly bleed and burp the air out before taking it for a ride. Do not leave air in coolant passages. I've had no issues with different brand coolant and oil.

Prestone is designed to be compatible with the Toyota Red coolant, which is also POAT. Should be fine.

I’ve had no issues with Prestone Platinum in my MK6 CJAA TDI. It’s been in for 4 year 65k mi.

I bought a 19 SEL brand new and have been using the Peak exclusively. I’ve had no issues.

my buddy put the Preston stuff in his v6 cause you can mix with all colors and hes been fine for 6 months now not an issue.

that prestone that says it can be mixed with any type of coolant can do just that. You can mix it with pretty much anything and it won't cause a problem. The industry is well aware that if you mix certain types of coolants, you will end up with a sludge so they make this prestone stuff too be compatible with everything. Now, just because it's compatible, doesn't mean it will last as long as some of the other coolants when they are 100% the exact coolant.

I’ve done it with my fiesta that had a leaking thermal housing I think I ended up topping it up so much by the end it was almost all Prestone wouldn’t personally do it on a car I care about though
