Zerex Asian Vehicle Red Antifreeze/Coolant 50/50 Prediluted 1 Gal — Silicate & Borate Free HOAT

Zerex Asian Vehicle Red is a ready-to-use 50/50 prediluted HOAT antifreeze/coolant engineered for Asian makes that need a red, silicate- and borate-free formula.

This one-gallon premixed coolant is formulated to match the fluid specifications commonly required by Toyota, Lexus, Scion and other Asian manufacturers that specify a red Hybrid Organic Acid Technology (HOAT) coolant with phosphate. It replaces the original factory fill in compatible vehicles and is designed to protect engine cooling systems against corrosion, scale and temperature extremes without adding silicates or borates.

How does this coolant protect my vehicle in everyday driving?

Zerex Asian Vehicle Red uses a long-life HOAT chemistry with phosphate corrosion inhibitors that safeguard all common cooling-system metals. The prediluted 50/50 mix is balanced for freeze and boil protection while resisting scale and deposit formation that reduce heat transfer.

• Prevents rust and corrosion on aluminum, copper and other metals
• Reduces scale and deposit buildup for consistent cooling
• Provides freeze and boil protection at factory-recommended levels

Is this the right coolant for my Asian make car?

This product is intended for Asian-made vehicles that specify a red, silicate-free HOAT coolant with phosphate. Always consult your owner’s manual or dealer to confirm compatibility before use to avoid mixing incompatible chemistries.

• Designed to meet OEM requirements for many Toyota, Lexus and Scion models
• Meets JIS K 2234 and other industry specifications for Asian applications
• Not recommended if your vehicle specifies a different color or inhibitor type

How long will the protection last once filled?

The patented long-life formula is engineered for extended service intervals, offering up to five years or 150,000 miles of protection under normal driving conditions. Service life depends on vehicle use, maintenance, and system condition, so follow manufacturer drain interval recommendations.

• Long-life corrosion protection for up to 5 years / 150,000 miles
• Formulated to minimize the need for premature coolant change-outs
• Prediluted for immediate use—no mixing with water required

What industry and OEM specifications does this coolant meet?

Zerex Asian Vehicle Red complies with multiple industry and manufacturer specifications relevant to Asian-market automobiles. These certifications indicate the formula has been tested to recognized performance standards for corrosion protection and thermal stability.

• Meets JIS K 2234-1994 and ASTM D4985 standards
• Compatible with Hyundai/KIA MS 591-08 and Mitsubishi ES-64217 guidance
• Also conforms to Ford WSS-M97B55-A and Federal A-A-870A where applicable
