PEAK OET Green Concentrate Antifreeze for Asian Vehicles, 1 Gal — POAT Extended Life & Corrosion Protection

PEAK OET Extended Life Green Concentrate is a phosphate-enhanced organic acid technology (POAT) antifreeze designed to protect Asian-manufacturer cooling systems for long service intervals.

This 1-gallon concentrated coolant mixes with water to form a long-lasting protection solution engineered for vehicles from Hyundai, Kia, Nissan, Mazda, Subaru, Mitsubishi, Infiniti, Genesis and Suzuki that specify a green POAT formula. It’s formulated to limit rust and corrosion across aluminum and ferrous components and is compatible with other extended-life antifreeze/coolants, making it suitable for routine flush-and-fill maintenance or targeted top-offs.

What makes this coolant suitable for Asian vehicles?

PEAK OET Green Concentrate matches the phosphate-enhanced POAT chemistry many Asian automakers require. Its additive package protects the specific metals and alloys used in these engines and radiator systems while maintaining compatibility with OEM recommendations when the correct coolant type is specified.

• Formulated to meet POAT specifications common to several Asian brands
• Protects aluminum heads, radiators, and water pumps
• Compatible with other extended-life coolants of similar chemistry

How long will protection last once properly installed?

When installed following a complete system flush and fill, PEAK guarantees up to 400,000 miles or 15 years of protection under normal operating conditions. This extended-life performance reduces the frequency of coolant changes when compared to conventional formulas.

• Guaranteed service life up to 400,000 miles or 15 years when used per instructions
• Concentrated formula lets you mix to the correct freeze/boil protection
• Ideal for long-term maintenance schedules and extended service intervals

How should I use this concentrate during maintenance?

Mix PEAK OET concentrate with water per your vehicle’s recommended ratio to achieve the required freeze and boil protection. Use it for a full system flush-and-fill or to top off coolant levels, taking care that only compatible coolants are mixed to avoid chemical imbalance.

• Dilute with distilled or deionized water to reach desired protection level
• Perform a full flush before filling for the guaranteed long service life
• Contains denatonium benzoate bittering agent—keep away from children and pets

What corrosion and leak protection does it provide?

The advanced inhibitor package minimizes rust and corrosion for all engine cooling system components, helping preserve pump seals, hoses, radiators, and alloy surfaces. Preventive protection reduces the risk of premature component failure associated with corrosive deposits.

• Inhibits rust and corrosion across mixed-metal systems
• Helps extend the life of water pumps, hoses, and gaskets
• Maintains coolant performance over extended intervals when installed correctly

Who is this for: PEAK OET Extended Life Green Concentrate is aimed at owners and technicians working on Asian-brand vehicles that call for a green POAT antifreeze. It’s suitable for independent shops, DIYers comfortable with coolant mixing and system flushing, and fleet managers seeking extended intervals between coolant services. Avoid use in vehicles that specify a different coolant chemistry (such as silicate hybrid or OAT variants) — always consult the vehicle owner’s manual for the recommended coolant type and mixing ratio.
