PEAK OET Red/Pink Concentrate Antifreeze Coolant for Asian Vehicles — 1 Gallon, POAT Corrosion Protection

PEAK OET Red/Pink Concentrate is a phosphate-enhanced POAT antifreeze formulated for Asian vehicles that require a red/pink solution, supplied as a 1-gallon concentrated coolant for flushing, filling, or topping off.

Designed to meet the coolant needs of many Toyota, Lexus and Scion models, this concentrated formula mixes with water to create a factory-compatible coolant that helps protect engine cooling systems from corrosion and scale. The concentrate is compatible with other extended-life antifreeze/coolants, includes a bittering agent for safety, and is intended for use when a phosphate-enhanced Organic Acid Technology (POAT) red or pink coolant is specified.

What does this coolant protect against?

This formulation focuses on preventing corrosion and deposit buildup that can shorten component life in cooling systems. It uses a blend of inhibitors tailored for metals and alloys commonly found in Asian-made engines and radiators.

• Corrosion inhibitors for aluminum, cast iron and soldered joints
• Scale and deposit reduction to maintain heat transfer
• Compatibility with water pump seals and hoses when mixed correctly

How should I mix and use the concentrate?

PEAK OET comes as a concentrate so you must dilute it with the correct ratio of distilled or deionized water to achieve the recommended freeze/boil performance. Follow the vehicle manufacturer’s dilution guidance, and use it during a full flush and fill or to top off an already compatible system.

• Typical mix: 50/50 concentrate-to-water for balanced freeze/boil protection (verify vehicle specs)
• Use distilled or deionized water to avoid mineral deposits
• Perform a complete system flush before switching coolant types when required

Is this coolant right for my car model?

PEAK OET Red/Pink is formulated to match the red/pink phosphate-enhanced POAT specification used in many Toyota, Lexus and Scion vehicles. Always check your owner’s manual or dealer guidance to confirm the required coolant type and color code for your exact year and engine.

• Recommended where manufacturers specify red/pink POAT coolants
• Not appropriate for systems that require hybrid or silicate-free formulas unless explicitly allowed
• Compatible with other extended-life antifreeze products, but follow mixing guidance

What warranty or service life can I expect?

When installed as part of a full flush and refill following the vehicle maker’s procedures, PEAK guarantees service-life protection up to 150,000 miles or 5 years. This guarantee applies under normal use and proper installation; keep service records and use recommended dilution ratios.

• Guaranteed protection: up to 150,000 miles or 5 years with proper flush/fill
• Includes Denatonium Benzoate bittering agent for safety against accidental ingestion
• Store in a cool, dry place and keep container sealed between uses

Who is this for? PEAK OET Red/Pink Concentrate is aimed at owners and technicians working on Toyota, Lexus and Scion vehicles that call for a phosphate-enhanced red or pink POAT coolant. It suits DIY mechanics performing maintenance, professional shops completing flush-and-fill services, and anyone who needs a concentrated, extended-life coolant compatible with common Asian vehicle cooling system materials. Verify your vehicle’s coolant color and specification before changing fluids, and follow the manufacturer’s instructions for mixing and replacement intervals.
