Antifreeze Prestone or OEM Volkswagen

I always use g13 from the dealer mainly because they can void any warranty for repairs on your cooling system if they see there is not g13 in there (g13 is pink, other types are purple) and with a model that is known to have coolant system issues, i aint giving them the excuse to not fix something they should.

Only use modern Volkswagen G12evo coolant! This is required not optional, if you mix the wrong coolants you can create an acidic meta eating coolant mixture that will ruin your engine

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

I use prestones all weather,Great stuff

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

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

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
