PEAK Global Lifetime 50/50 Prediluted Antifreeze & Coolant 1 Gal — Ready-to-Use, Corrosion Protection

PEAK Global Lifetime 50/50 Prediluted Antifreeze and Coolant is a ready-to-use, ethylene glycol-based coolant that protects vehicle cooling systems from corrosion and freeze/thaw damage for the life of the system with proper maintenance.

This one-gallon, 50/50 prediluted formula is engineered to be poured directly into radiators or expansion reservoirs without mixing. It uses organic acid technology to protect aluminum, iron, and other cooling-system metals from rust and corrosion while remaining compatible with many existing glycol-based coolants. The amber coloring makes it safe for topping off because it won’t drastically alter the color already in your cooling system, and the formulation includes a bittering agent to deter accidental ingestion.

How do I use PEAK Global Lifetime 50/50 Prediluted Antifreeze and Coolant?

Using this product requires no dilution—simply add it to the cooling system when the engine is cool. For a complete coolant change, follow your vehicle manufacturer’s service procedure for draining and refilling the system; for top-offs, open the overflow or radiator cap only when cool and pour until the recommended level.

• Ready-to-use 50/50 concentration—no water required.
• Top off via expansion tank or radiator neck when engine is cold.
• Follow vehicle-specific service manual for full system flush and refill.
• Contains denatonium benzoate as a bittering agent for safety.

Will this coolant work with my car, truck, or SUV?

PEAK Global Lifetime is formulated for broad compatibility across American, Asian, and European vehicles, including light, medium, and heavy-duty trucks. It’s designed to mix with other ethylene glycol-based antifreezes and is safe for use with common cooling-system materials, though mixing different coolant chemistries is generally discouraged unless they share the same base type.

• Compatible with most ethylene glycol-based coolants.
• Suitable for cars, SUVs, pickups, and many commercial trucks.
• Protects aluminum, cast iron, and brass components from corrosion.
• Not intended for phosphate- or silicate-exclusive formulations without checking compatibility.

What protection and maintenance benefits can I expect?

The product provides corrosion control and freeze/boil protection when used as recommended, helping to maintain cooling efficiency and prevent premature component wear. With routine checks and proper fluid levels, the formula is designed to offer long-term protection to the cooling system.

• Corrosion inhibitors protect critical metals in the cooling system.
• Pre-mixed 50/50 blend gives reliable freeze and boil protection for typical climates.
• Amber color minimizes visual disruption when topping off existing coolant.
• Organic Acid Technology supports extended-life performance with scheduled maintenance.

Is this safe to store and handle at home or in a shop?

The container is intended for standard automotive storage; keep it sealed and stored upright in a cool, dry place away from children and pets. The formula contains ethylene glycol, which is toxic if ingested, so avoid spills and dispose of used coolant per local hazardous-waste guidelines.

• Store in original, tightly closed container away from heat sources.
• Use protective gloves and avoid skin contact when pouring.
• Dispose of old coolant at authorized recycling or hazardous-waste facilities.
• Includes a bittering agent to reduce risk of accidental ingestion.

Who is this for: PEAK Global Lifetime 50/50 Prediluted Antifreeze and Coolant is intended for vehicle owners, professional mechanics, and fleet managers who want a convenient, ready-to-use coolant that fits a wide range of cars and trucks. It’s a practical choice for routine maintenance, emergency top-offs, and full coolant service when an ethylene glycol-based solution is specified by the manufacturer. If you need lifetime-style corrosion protection with the ease of a pre-mixed gallon, this product delivers broad compatibility and straightforward application.
