Zerex Asian Vehicle Green 50/50 Ready-to-Use Antifreeze/Coolant - Case

In this review the Zerex Asian Vehicle Green 50/50 Ready-to-Use Antifreeze/Coolant is evaluated for owners of Asian-brand cars and trucks who need a reliable, pre-mixed cooling fluid. The bottom line: this coolant is for drivers who want an OEM-style formula that protects against freezing, boiling and corrosion without the hassle of mixing, and its HOAT phosphate protection is the single biggest reason to choose it for Acura, Honda, Infiniti and Nissan applications.

Key Features

• Ready-to-use 50/50: Comes pre-mixed with deionized water so it installs quickly and provides immediate protection to -34F and up to 265F against boiling.
• HOAT formulation: Hybrid Organic Acid Technology with a phosphate additive helps prevent corrosion, scale and rust on radiators and water pumps including aluminum parts.
• Silicate and borate free: Matches the green formula specified by many Asian manufacturers that require silicate and borate-free coolant chemistry.
• Leak and material safe: High-quality additives are formulated to avoid harming gaskets, hoses, plastics or original vehicle finishes while helping reduce the risk of leaks.
• Long service protection: Backed by a 5 year/150,000 mile guarantee against freeze-up and boil-over related engine failure for long-term peace of mind.

Who It's For

This coolant is aimed squarely at owners and fleet managers of Asian-brand vehicles such as Acura, Honda, Infiniti and Nissan that specify a green, silicate and borate-free HOAT formula. It is also a practical choice for anyone who prefers a pre-mixed product to avoid dosing errors and wants corrosion protection for aluminum and mixed-metal cooling systems.

Those who should look elsewhere include owners of vehicles that require a different color or chemistry (for example red or pink long-life formulas) or drivers who prefer concentrated antifreeze to custom-mix stronger or weaker ratios; always check your vehicle manual before switching coolant types.

Pros & Cons
