Best Antifreeze for Volkswagen Golf

I use peak violet european formula in my mk8 R.

I keep this in the trunk of my mk7. Haven’t had to use it, but I feel comfortable using it in emergencies

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.

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

I've used pentosin E for full flushes of two Golfs (2015 and 2017). No issues. Prior to that, I used it for topping off. It's the right stuf being G13 regardless of slight color variation pink/purple.

Do not, under any circumstances, mix generic auto store coolant with G12/13. If you are low, top it up with water - distilled preferably.

When I did my MKIII flush I ran 9 gallons of distilled water through the system first to ensure there wasn't any mixing of coolants. I was also using a professional radiator flushing machine. I then used Prestone Extended Life Coolant. I never had a cooling related issue in the 5 years I owned that car.

i use prestone dex cool. (for the coolant) it says its made for GM cars but i use it and it kicks ass.

I don’t use peak anything. it’s actually not great coolant.

I also had the coolant replaced. I asked for the OEM stuff, which I guess is pink (?). They said mine was pretty much black !
