PEAK Global Lifetime Antifreeze and Coolant Concentrate — 1 Gal, POAT Long-Lasting Corrosion Protection

PEAK Global Lifetime Concentrate is a universal, POAT-based antifreeze and coolant designed to protect every vehicle's cooling system for the life of the car when used with proper maintenance.

Built to work with American, Asian, and European vehicles, this amber concentrate mixes to provide long-lasting corrosion protection across all cooling-system metals, including aluminum. Its stabilized phosphate-enhanced organic acid technology (POAT) delivers corrosion inhibition without silicates, borates, nitrites, or amines, and the formulation is safe for top-offs because it won't alter the color of your existing coolant. Available as a concentrate for custom mixing or as a 50/50 pre-diluted option, PEAK Global Lifetime helps simplify coolant compatibility and maintenance.

How does this coolant protect my engine metal surfaces?

PEAK Global Lifetime uses an organic-acid corrosion inhibitor system that establishes a protective film on metal surfaces. This film prevents electrochemical reactions that cause rust and pitting, extending radiator, water pump, and head gasket life.

• Stabilized POAT formulation for multi-metal protection
• Fast-acting inhibitors that bond to aluminum and steel
• Long-lasting performance when combined with proper flush and fill schedules

Is this antifreeze compatible with the coolant already in my vehicle?

Yes — the concentrate is formulated to be compatible with most existing antifreeze chemistries and safe for top-offs, thanks to its non-abrasive OAT/POAT chemistry. It was developed to meet or exceed the technology requirements of a wide range of makes and models.

• Mixable with many ethylene-glycol-based coolants
• Amber color designed not to change your system’s current coolant color
• Contains Denatonium Benzoate as a bittering agent for safety

How do I use the concentrate — what mixing and maintenance are required?

This concentrate allows you to mix to the desired freeze/boil protection level (commonly 50/50 for balanced protection). For best results, perform a complete system flush and fill at recommended service intervals and top off with the concentrate when needed.

• Mix concentrate with water to reach manufacturer-recommended ratios (50/50 typical)
• Perform a full cooling-system flush before switching to this product for guaranteed compatibility
• Top-offs are safe because the amber tint won't affect system color indicators

Will this work for heavy-duty trucks and older cars?

Yes — PEAK Global Lifetime is intended for passenger cars as well as light, medium, and heavy-duty truck cooling systems. Its formulation was developed to meet the performance needs across vehicle ages and types when used according to service guidelines.

• Designed for automotive and truck applications across global makes
• Suitable for older systems when a proper flush is completed first
• Available as concentrate or 50/50 for different service approaches

Who is this for: PEAK Global Lifetime Concentrate is aimed at vehicle owners, fleet managers, and repair technicians who want a single, long-lasting coolant that reduces compatibility worries. If you service multiple makes or prefer to mix coolant to exact concentrations, or if you need a corrosion inhibitor safe for aluminum and other metals, this product provides a practical, maintenance-friendly option. Always follow your vehicle manufacturer's coolant recommendations and perform a complete flush before switching product chemistries for best results.
