ZEREX Asian Vehicle Antifreeze/Coolant is specifically formulated to meet the requirements of Asian vehicle manufacturers (Toyota®, Lexus®, Scion® and others) requiring a red, silicate free Hybrid Organic Acid Technology (HOAT) with a phosphate additive. This patented formula is designed to replace the original fluid and provides protection from rust, corrosion, boil overs and freezing.

Product Features:

• Formulated to replace the OEM fluid in Asian make vehicles such as Toyota®, Lexus®, Scion® and others requiring a red, silicate free HOAT antifreeze/coolant
• Silicate-free, long-life, phosphate Hybrid Organic Acid Technology chemistry
• The long life formula provides protection for all cooling system metals from rust and corrosion. The silicate free, borate free formula helps protect against harmful scale and deposits
• Meets the following OEM and industry specifications: JIS K 2234-1994, Hyundai/KIA MS 591-08, Mitsubishi ES-64217, Ford WSS-M97B55-A, ASTM 3306, ASTM D4985, Federal Specification A-A-870A

Pentofrost A4 is a phosphated organic acid technology (phosphated OAT); which is categorized as HOAT (hybrid organic acid technology) in the US market. Pentofrost A4 is suitable for all Asian vehicles using pink Antifreeze/Coolant. Pentofrost A4 does not contain any silicate, borate, nitrite or amine containing additives since these may harm your Asian vehicle. Do not mix with other coolants (especially silicated coolants), as this may cause el formation and clog your radiator. Pentofrost A4 is a PRE-DILUTED antifreeze for Asian vehicle applications in water-cooled engines. It contains phosphates and organic salts to protect all materials used in cooling systems for Asian vehicles. Pentofrost A4 is mixable with all phosphated OAT. Meets ASTM D-3306.

Product Features:
