Zerex Asian Green Coolant - 1 Gallon (Pre-Mix)

Zerex Asian Green Coolant - 1 Gallon

OEM-Approved P-OAT Protection for Hyundai, Kia, Mazda, and Mitsubishi

Ensure your cooling system operates with factory-level precision using Zerex Asian Green. This 50/50 ready-to-use formula is engineered to match the specific chemical profile required by many Asian makes, which typically forbid the use of silicates and borates. By utilizing a phosphate-enhanced Organic Acid Technology, it creates a protective film on internal metal surfaces that guards against the four main causes of cooling system failure: corrosion, leaking, deposits, and extreme temperature fluctuations. Because it comes pre-mixed with demineralized water, it takes the guesswork out of maintenance and ensures the perfect ratio every time.

What Included in the Box:

- (1) 1 Gallon (3.78L) Bottle: 50/50 Ready-to-Use Pre-mix.

The Zerex Advantage

- Asian Vehicle Specific P-OAT: Formulated with a phosphated organic acid technology that is specifically required by many Asian OEMs to protect water pump seals and aluminum components.

- Silicate and Borate Free: Eliminates the abrasive silicates and borates that can damage the cooling systems of vehicles designed for P-OAT chemistry.

- 5-Year / 150,000 Mile Protection: Provides a long service life, maintaining its anti-corrosion and heat-transfer properties far longer than conventional green coolants.

- Superior Cavitation Protection: Specifically guards against the "pitting" of water pump impellers and cylinder liners caused by air bubbles in the system.

- Consistent Thermal Performance: Maintains stable operating temperatures in extreme environments, protecting against winter freeze-ups down to -34 degrees F and summer boil-overs up to 265 degrees F.

Precision Tip: This is a 50/50 Pre-mix, meaning you should never add additional water to this bottle. Adding tap water can introduce minerals that neutralize the P-OAT inhibitors and lead to scale buildup. If you are switching from a different color or "universal" coolant, we highly recommend a full system flush with distilled water before filling with Zerex Asian Green to ensure the chemistry isn't compromised.
