PEAK OET Extended Life Blue Concentrate Antifreeze/Coolant 1 Gal — POAT protection, for Asian vehicles

Built to meet the coolant specifications recommended by many Japanese and Korean automakers, this blue PEAK OET concentrate mixes with water to create a long-life coolant that helps resist rust and corrosion across aluminum and mixed-metal cooling systems. It contains Denatonium Benzoate as a bittering agent for safety and is backward-compatible with other extended-life antifreeze/coolants when mixed and installed correctly. PEAK backs the product with a service-life guarantee when used as part of a complete flush and fill.

How does PEAK OET concentrate protect my engine's cooling system?

The formula uses organic acid inhibitors plus phosphate technology to form protective layers on metal surfaces, slowing corrosion and scale formation. That protection helps preserve the radiator, water pump, heater core, and head gasket areas over extended service intervals.

• Prevents rust and corrosion on aluminum and mixed-metal systems
• Helps maintain water pump and heater core integrity
• Reduces buildup that can impede coolant flow
• Contains bittering agent for accidental ingestion deterrence

Will this coolant work in my Acura, Honda, Infiniti, or Nissan?

PEAK OET blue concentrate is specifically designed for Asian vehicles that call for a POAT-style, phosphate-enhanced blue coolant. It matches the performance profile many of these manufacturers specify, but always confirm your vehicle’s owner manual or service literature before use.

• Recommended for Acura, Honda, Infiniti, Mitsubishi, Nissan, Subaru, Suzuki
• Suitable when a blue POAT/extended-life coolant is specified
• Compatible with other extended-life formulas when mixed properly

How do I mix and install the 1-gallon concentrate?

This product is a concentrate meant to be diluted with water according to the vehicle manufacturer’s recommended ratio—commonly 50/50 for year-round freeze/boil protection. For best results perform a complete flush and fill; topping off is acceptable between service intervals if contamination is absent.

• Mix with distilled or deionized water per manual (typically 50/50)
• Perform a full flush and fill for maximum longevity and warranty eligibility
• Use correct disposal methods for old coolant—follow local regulations

What service life and warranty coverage does PEAK provide?

When PEAK OET Extended Life is installed as part of a complete flush and fill, PEAK guarantees service protection up to 150,000 miles or 5 years. That coverage applies under normal operating conditions; retain proof of service and follow recommended procedures to qualify.

• Guaranteed up to 150,000 miles or 5 years with proper installation
• Service proof and correct flush/fill procedure required for warranty
• Concentrate form allows flexible use for flushes, fills, or top-offs

Who is this for? PEAK OET Extended Life Blue Concentrate is aimed at owners and technicians working on Asian-brand cars and light trucks that specify a blue POAT extended-life coolant—especially shops and DIYers who perform routine cooling-system maintenance or full flushes. If you need a concentrated, long-life solution compatible with aluminum components and mixed-metal systems, and you follow manufacturer dilution and service procedures, this product provides a practical, warranty-backed option.
