It’s a concentrated mix intended for dilution with water, making it suitable for flushing, filling, or topping off a system. The formula includes protection against rust and other forms of coolant degradation, and contains a bittering agent (Denatonium Benzoate) to discourage accidental ingestion.\u003c\/p\u003e\n\n\u003ch3\u003eWhat vehicles is this coolant made for?\u003c\/h3\u003e\n\u003cp\u003eThis antifreeze concentrate is tailored to fit European cars that require a silicate‑enhanced organic acid technology (Si‑OAT) coolant. Common compatible makes include select Audi, Mercedes‑Benz, Porsche, and Volkswagen models, but always verify your owner’s manual or dealer guidance before use. The violet color helps distinguish it from other coolant families during service.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSuitable for many European models that specify violet Si‑OAT coolant\u003c\/li\u003e\n  \u003cli\u003eWorks with cooling systems using silicate‑enhanced OAT chemistry\u003c\/li\u003e\n  \u003cli\u003eConcentrated formula for custom dilution ratios\u003c\/li\u003e\n  \u003cli\u003eColor coding aids correct coolant identification\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does this concentrate protect my engine and cooling components?\u003c\/h3\u003e\n\u003cp\u003ePEAK OET’s formulation helps limit corrosion and scale formation on metal and alloy components of the cooling system.
