Zerex G30 Purple Coolant - 1 Gallon (Pre-Mix)

Zerex G30 Purple Coolant - 1 Gallon

Professional Grade OAT Protection for European and Heavy-Duty Engines

Ensure your cooling system operates with factory-level precision using Zerex G30. This purple/violet formula is engineered for vehicles requiring the G12 or G12+ standard, commonly found in European performance brands and modern aluminum-block engines. By utilizing a NAP-free (Nitrite, Amine, Phosphate-free) and silicate-free chemistry, it prevents the formation of abrasive deposits and protects against the four main causes of cooling system failure: corrosion, leaking, deposits, and extreme temperature fluctuations. Whether you are performing a full system flush or a seasonal service, Zerex G30 offers the exact chemical profile needed to maintain engine health and cooling efficiency.

What Included in the Box:

- (1) 1 Gallon (3.78L) Bottle: Full-strength concentrate.

The Zerex Advantage

- OEM Approved OAT Chemistry: This is the precise factory-fill chemistry for many European brands, ensuring your gaskets, hoses, and plastics remain safe from chemical degradation.

- Organic Acid Technology (OAT): Features a silicate-free and phosphate-free formula that provides up to 5 years or 150,000 miles of protection by forming a thin, protective layer on metal surfaces.

- Unsurpassed Thermal Stability: Provides a massive safety margin against summer boil-overs and winter freeze-ups, maintaining a stable operating temperature even under heavy track or towing loads.

- Aluminum Protection: Specifically formulated to protect modern aluminum engines from high-temperature pitting and cavitation, which can lead to water pump failure.

- Warranty Compliance: Meets or exceeds the performance requirements of leading manufacturers like VW, Audi, and Porsche, ensuring your vehicle stays protected to factory standards.

Precision Tip: This is a concentrate formula and must be mixed with distilled or deionized water for use. We recommend a 50/50 mix for most climates. Never use tap water for a flush or top-off, as the minerals can react with the OAT inhibitors and cause scale buildup that restricts flow and reduces cooling efficiency.
