PEAK Orange OET Extended Life Antifreeze/Coolant Concentrate 1 Gal — OAT, 150,000‑Mile Protection

PEAK OET Extended Life Orange Concentrate Antifreeze/Coolant is a 1‑gallon, concentrated orange organic acid technology (OAT) coolant formulated to protect North American Ford, Chrysler, and GM cooling systems for up to 150,000 miles or 5 years when installed during a complete flush and fill.

This concentrated antifreeze/coolant blends into your vehicle's cooling system to help control rust and corrosion while remaining compatible with other extended life coolants. It contains a bittering agent (Denatonium Benzoate) to discourage accidental ingestion and is designed for use in modern North American engines that specify an orange OET fluid. Offered as a 1‑gallon container, it’s convenient for flushing, filling, or topping off systems and works with recommended dilution ratios for many passenger cars and light trucks.

Which vehicles should use PEAK OET Orange Concentrate?

PEAK OET is intended for North American vehicles that call for an orange OAT/OET coolant, commonly found in many Ford, Chrysler, and GM models. Always check the vehicle owner’s manual or service label to confirm compatibility before adding any coolant.

• Recommended for Ford, Chrysler, and GM vehicles specifying orange OET/OAT fluids
• Suitable for passenger cars, SUVs, and light trucks in North America
• Not for use where traditional green IAT or non‑OAT coolants are specifically required

How does this concentrate protect the cooling system?

The formula combines corrosion inhibitors with organic acid technology to slow rust and scale formation inside the radiator, water pump, heater core, and other metal components. Regular use as part of a proper service procedure helps maintain coolant pathways and thermal transfer efficiency.

• Helps prevent rust and corrosion on aluminum and ferrous components
• Formulated to protect the entire cooling circuit, including hoses and seals
• Compatible with other extended life coolants for service flexibility

What service life and warranty coverage does PEAK offer?

When PEAK OET is installed as part of a complete flush and fill according to the product instructions, the manufacturer guarantees protection for up to 150,000 miles or 5 years. This coverage applies to the cooling system’s service life when the product is used correctly.

• Guarantee: up to 150,000 miles or 5 years after proper installation
• Requires a full flush and fill to qualify for guaranteed protection
• Keep purchase and service records to validate coverage

How should I use this 1‑gallon concentrate during maintenance?

The concentrate is designed for mixing to the correct dilution ratio prior to adding it to the cooling system. It’s ideal for complete coolant replacements, routine topping off, or during system flushes where an extended life orange coolant is required.

• Mix with distilled water to manufacturer-recommended concentration (check label)
• Use for flush and fill procedures or as a top-off for compatible systems
• Contains Denatonium Benzoate to reduce accidental ingestion risk

Who is this for: PEAK OET Extended Life Orange Concentrate is aimed at owners and technicians working on North American vehicles that specify orange OET/OAT coolants—especially Ford, Chrysler, and GM models. It suits do‑it‑yourself mechanics who perform regular coolant service and professional shops handling flush and fill maintenance. If your vehicle requires a different coolant type (for example, traditional green IAT), choose the fluid the manufacturer specifies.
