PRECISION COOLING PROTECTION FOR HONDA, NISSAN, AND SUBARU

Prestone (PRS) Asian Blue 50/50 Antifreeze/Coolant is a specialized, high-performance fluid engineered for vehicles requiring a Blue phosphate-enhanced OAT formula. It is designed to provide the exact chemical balance required by leading Asian manufacturers to ensure long-term engine reliability.

Why choose Prestone Asian Blue 50/50?

Asian-designed engines often utilize specific alloys that require Phosphate Organic Acid Technology (POAT) to prevent the buildup of scale and protect the water pump. This formula features patented Cor-Guard technology, which provides an instant protective layer against the primary causes of cooling system failure. Because it is pre-diluted to a 50/50 ratio, it ensures the perfect antifreeze-to-water balance, protecting your engine in temperature extremes from sub-zero winters to scorching summers.
