Prime Guard Universal Concentrated Antifreeze/Coolant is a high-performance, ethylene glycol-based formula designed to deliver year-round protection for all makes and models of passenger vehicles and light-duty trucks. Engineered with advanced corrosion inhibitors and long-life technology, this universal formula is compatible with any color antifreeze and can be safely mixed with existing coolant without compromising performance.

Key Features & Benefits:

• Universal Compatibility: Formulated to work with all types and colors of antifreeze/coolant (green, orange, yellow, blue, red), making it ideal for top-offs or complete system flushes.
• Concentrated Strength: Allows for custom dilution based on climate and vehicle requirements. Mix with distilled water to achieve the desired freeze/boil protection.
• Long-Life Protection: Provides up to 5 years or 150,000 miles of protection when properly maintained, reducing the need for frequent coolant changes.
• Advanced Corrosion Inhibitors: Protects aluminum, cast iron, steel, solder, and copper components from rust and corrosion, extending the life of your radiator and cooling system.
• All-Season Performance: Delivers reliable freeze protection in winter and boil-over protection in summer, ensuring optimal engine temperature regulation in all driving conditions.
• Meets or Exceeds Industry Standards: Compatible with ASTM D3306 and D4985 specifications for automotive and light-duty applications.

Recommended Uses:

• Passenger cars
• SUVs and light trucks
• Vans and crossovers
• Compatible with both domestic and foreign vehicles

Mixing Instructions:

• 50/50 Mix: Combine 1 part antifreeze with 1 part distilled water for standard protection down to -34°F and boil-over protection up to 265°F (with a 15 psi radiator cap).
• Custom Mix Ratios: Adjust concentration for more extreme climates as needed.
