PEAK OET Antifreeze/Coolant 50/50 Prediluted — Blue 1 Gal for Asian Vehicles, POAT, 150K‑mile Protection

If you drive an Acura, Honda, Infiniti, Mitsubishi, Nissan, Subaru, or Suzuki that specifies a blue, phosphate-enhanced Organic Acid Technology (POAT) coolant, this one-gallon jug gives you a convenient 50/50 premix for quick top-offs or partial fills. The formula is engineered to be compatible with other extended-life coolants and includes a bittering agent (Denatonium Benzoate) for safety. PEAK backs the product with a protection guarantee when installed after a complete flush and fill.

How does this coolant protect my engine cooling system?

The PEAK OET formulation inhibits rust and corrosion across metal surfaces inside the cooling system, helping maintain radiator, water pump, hoses, and heater core integrity. Its organic acid inhibitors target electrochemical wear while maintaining neutral pH balance for long-term stability.

• Prevents rust and scale buildup on aluminum and ferrous parts
• Reduces corrosion that can cause leaks and component failure
• Maintains inhibitor concentration in a 50/50 premix for reliable protection

Is this coolant ready to use out of the bottle?

Yes—this product is prediluted 50/50 with high-purity water, so it is ready for immediate topping off or filling without additional mixing. That saves time and avoids common dilution mistakes that can reduce freeze and boil protection.

• 50/50 premix for safe freeze and boil protection
• Ideal for quick top-offs between scheduled services
• Eliminates need for separate antifreeze and distilled water
