PEAK Orange OET OAT Coolant Concentrate 1 gal — Long-Life Antifreeze, 150,000‑Mile Protection

PEAK OET Orange Concentrate is a one-gallon organic-acid-technology (OAT) coolant concentrate formulated to protect North American engines from corrosion and overheating when mixed and installed correctly.

This concentrated orange antifreeze is made for modern North American passenger vehicles that specify an OAT orange formula. It mixes with water to create a long-life coolant that helps inhibit rust and corrosion across aluminum and other cooling-system metals. The product includes a bittering agent to discourage accidental ingestion and is designed for use in flush-and-fill services or for topping off when compatible with existing coolant.

Which vehicles are compatible with this orange coolant?

PEAK OET Orange is formulated to meet the organic acid technology specifications commonly required by many Ford, Chrysler, and GM models. Always check your owner's manual for the recommended coolant type before switching fluids to ensure compatibility with your engine materials and gasket types.

• Recommended for Ford, Chrysler, and GM vehicles specifying orange OAT coolant.
• Works with systems that call for extended-life organic acid technology formulas.
• Compatible with other extended-life antifreeze/coolants when mixed per directions.

How should I use the concentrate when servicing a cooling system?

This product is a concentrate intended to be mixed with water at the proper ratio for your vehicle — typically 50/50 unless the vehicle manufacturer specifies otherwise. Use it during a complete cooling-system flush and fill or to top off an existing compatible OAT coolant; follow service instructions and safety precautions on the label.

• Mix concentrate with distilled or deionized water per vehicle recommendation.
• Use during a full flush-and-fill for best protection; can also top off compatible coolant.
• Follow manufacturer service intervals and disposal guidelines for old coolant.

What protection and service life does this coolant offer?

PEAK guarantees protection up to 150,000 miles or five years when the product is installed as part of a complete flush-and-fill service. The formulation helps inhibit corrosion and scale buildup across engine cooling components, supporting long-term reliability when maintenance intervals are followed.

• Guard against rust and corrosion for cooling system metals and components.
• Guaranteed up to 150,000 miles or 5 years with proper installation as part of a complete service.
• Contains inhibitors designed for extended-life performance in compatible vehicles.

Are there safety or handling considerations I should know?

The concentrate includes Denatonium Benzoate, a bittering agent added to discourage ingestion; it remains a chemical product and should be handled carefully. Use gloves and eye protection, avoid skin contact, and store out of reach of children and pets; dispose of used coolant according to local hazardous-waste regulations.

• Bittering agent added to reduce accidental ingestion risk.
• Wear protective gear when handling and avoid spills on painted surfaces.
• Recycle or dispose of old coolant at an approved facility.

Who is this for: PEAK OET Orange Concentrate is aimed at owners and technicians working on North American cars and light trucks that require an orange OAT coolant. It suits professional shops performing flush-and-fill service and do-it-yourselfers who follow manufacturer mixing ratios and safety directions, seeking extended-life corrosion protection and compatibility with Ford, Chrysler, and GM cooling systems.
