PEAK OET Extended Life Pink Concentrate Antifreeze/Coolant for European Vehicles, 1 Gal.

I’ve used PEAK products before, but this OET Extended Life Pink Concentrate really impressed me. It’s specifically formulated for European vehicles, and as someone who owns an Audi, it’s reassuring to know this coolant meets the phosphate-free, silicate-free requirements recommended by manufacturers like VW, BMW, and Mercedes-Benz.Mixing and application were straightforward. Since it’s a concentrate, I diluted it 50/50 with distilled water before adding it to the system. The pink color matched my factory fill perfectly, and I had zero compatibility issues after topping off and running the system.Performance-wise, it holds up well even under high-load driving conditions. I’ve taken my vehicle through several temperature swings over the past month—cold mornings and hot commutes—and the engine temperature stayed steady throughout. No bubbling, no pressure build-up, no discoloration.What stands out:OEM compatibility without the dealership markupExcellent long-life protection (claimed up to 150,000 miles or 5 years)Trusted brand with clear labeling and instructionsMinor note: Since this is concentrate, don’t forget to mix with distilled water—some may prefer a premix for convenience, but I like the control and value concentrate offers.For anyone maintaining a European vehicle and looking for a high-quality, OEM-spec coolant that won’t break the bank, this is a smart pick. Highly recommended for DIY maintenance or full flushes.

If you have a European car, you probably need this. Lower price than your local auto parts store.

Works perfectly

Coolant types are complicated.... G12 and G12+ are 2 different coolant types. G12 is OAT technology and pink - G12 is marked on the reservoir but also be sure to also check the owners manual to see if they mean't G12+G12+ is SOAT technology and violet/purple. And it's ok to mix G12 and G12+ These 2 coolant types changed by vehicle year.OAT antifreeze is free of silicates and phosphates, reducing the risks of scaling and seal corrosion. Various manufacturers have customized OAT formulations, offering coolants like Subaru Blue, Toyota Red, and VW/Audi’s G12 Purple.

Works fine, but even in concentrate form it's too clear in color. I can see it in the reservoir, but a darker pink hue would help a bit. Good value with that one nitpick.

Works as expected, not better or worse than other brand names! Honestly purchased for the price.

I had ordered this to do a heater core flush before it got too cold and then went to AutoZone to grab some in person as it was arriving a day too late (for weather not due to amazon) and was charger $43 for two premixed cause they didn't have any concentrate of the pink g12 type I needed and then when I was working on my car Amazon arrives with my $24 bottle of concentrate and was able to return the other rip off bottles and get two gallons for $24 with just mixing in distilled water. Thanks!

Great deal, as advertised
