PEAK Antifreeze/Coolant Concentrate 1 Gal — OET Gold HOAT Extended Life, Corrosion Protection

This 1-gallon concentrated coolant from PEAK is engineered to be mixed with water to create an extended life, hybrid organic acid technology (HOAT) formula recommended for many Ford and Chrysler applications and compatible with other extended life coolants. It contains a bittering agent (Denatonium Benzoate) for safety and is intended for flushing, filling, or topping off engine cooling systems. When installed as part of a complete flush and fill, PEAK supports up to 150,000 miles or 5 years of service life protection.

How do I use this concentrate in my vehicle?

Mix PEAK OET Extended Life Gold concentrate with deionized or distilled water according to your vehicle manufacturer’s recommended ratio—typically 50/50 for freeze and boil protection. Always drain and flush the cooling system first for best results and refill with the properly mixed solution to ensure consistent protection and heat transfer.

• Use distilled or deionized water to avoid mineral deposits.
• Follow vehicle-specific mixing ratios; 50/50 is common.
• Perform a complete flush before filling for guaranteed service life.
• Top off between scheduled services as needed to maintain level.

Will this coolant protect against rust and corrosion?

Yes — the formula includes corrosion inhibitors designed to safeguard aluminum, iron, and other cooling system metals found in North American vehicles. It helps maintain component integrity and reduces scale and build-up when combined with proper maintenance.

• Protects engine blocks, radiators, and heater cores.
• Formulated to control electrochemical corrosion in mixed-metal systems.
• Compatible with other extended life coolants for top-ups.
