PEAK OET Extended Life Red/Pink Antifreeze/Coolant Concentrate, 1 Gal — POAT Formula, 150,000-mile (5-yr) Protection

This 1-gallon concentrated antifreeze/coolant is designed for technicians and DIYers who need a long-life, red/pink POAT formula compatible with specific Asian vehicle specifications. It mixes with water to form a ready-to-use solution, protects metal components from corrosion, and contains a bittering agent (denatonium benzoate) to discourage accidental ingestion. The product is compatible with other extended-life antifreeze/coolants and is intended for full system flush-and-fill procedures to maximize service life.

What vehicles should use this red/pink PEAK OET formula?

Use this coolant in Asian brands that specify a red/pink phosphate-enhanced organic acid technology (POAT) formula, most commonly recommended by Lexus, Scion, and Toyota models. Always check your owner’s manual or service documentation to confirm the coolant specification before replacing or topping off the system.

• Meets OE-type requirements for many Lexus, Scion, Toyota models
• Intended where red/pink POAT is specified rather than silicate or OAT formulations
• Not a universal substitute—verify vehicle coolant spec first

How does this concentrate protect engine cooling system components?

The advanced inhibitor package in this formulation slows rust and corrosion inside radiators, water pumps, heater cores, and cylinder heads. When mixed and installed correctly during a complete flush and fill, it helps maintain clean coolant passages and metal integrity over extended service intervals.

• Phosphate and organic acid chemistry combats scale and corrosion
• Formulated to protect aluminum and other common engine metals
• Compatible with other extended-life antifreeze/coolants for service flexibility

What service life can I expect after a proper flush and fill?

When the cooling system is fully flushed and refilled with this concentrate at the correct mix ratio, PEAK guarantees protection for up to 150,000 miles or 5 years. Service life assumes correct dilution, use of clean water or distilled water, and adherence to recommended maintenance intervals.

• Guaranteed protection up to 150,000 miles or 5 years with proper installation
• Concentrated product requires mixing to achieve specified freeze/boil protection
• Optimal results follow a professional or thorough DIY flush-and-fill

How should I mix and apply this coolant concentrate?

Mix the concentrate with clean water per the vehicle manufacturer's recommended ratio to achieve the desired freeze and boil protection. Use this product for a full system flush, a complete refill, or as a proper top-off after verifying compatibility with the existing coolant.

• Typical dilution is 50/50 with distilled or demineralized water unless otherwise specified
• Use during a full flush-and-fill for the guaranteed service interval
• Contains denatonium benzoate to deter accidental ingestion—handle safely and keep out of reach of children and pets

Who is this for? PEAK OET Extended Life Red/Pink Concentrate suits owners and technicians working on Asian vehicles that require a phosphate-enhanced red/pink POAT coolant—especially Lexus, Scion, and Toyota models. Choose this 1-gallon concentrate if you want a long-life, installer-mixed solution for flush-and-fill maintenance and value a formulation built to limit rust and corrosion while remaining compatible with other extended-life coolants. Always confirm your vehicle’s coolant specification and follow safe handling and disposal practices.
