Zerex G40 Pink Coolant - 1 Gallon

Zerex G40 Pink Coolant - 1 Gallon

OEM-Approved Protection for Audi, VW, and Porsche Engines

Ensure your cooling system operates with factory-level precision using Zerex G40. This pink/violet formula is the preferred choice for the Volkswagen Group and other European manufacturers who specify the G12++, G13, or G40 standards. By utilizing a NAP-free (Nitrite, Amine, Phosphate-free) chemistry, it prevents the formation of hard water scale 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 simple seasonal top-off, Zerex G40 offers the exact chemical profile needed to maintain warranty compliance and maximize engine life.

Available Variants:

- G40 Concentrate (861526): A full-strength formula that must be mixed with distilled water. This is the most cost-effective option for a complete system flush or for users who need to customize their freeze protection levels for extreme climates.

- G40 50/50 Pre-Mix (861399): A ready-to-use solution pre-diluted with deionized water. Perfect for quick top-offs or for users who want to avoid the mess and guesswork of mixing their own ratio.

The Zerex Advantage

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

- Si-OAT Technology: Combines the fast-acting protection of silicates with the long-lasting life of organic acid technology for up to 5 years or 150,000 miles of protection.

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

- Advanced Metal Protection: Specifically formulated to protect aluminum, cast iron, steel, copper, and brass from rust, scale, and cavitation.

- Warranty Compliance: Formulated to meet or exceed the performance requirements of leading European manufacturers, ensuring your vehicle stays protected according to factory standards.

Precision Tip: When using the Concentrate variant, always mix with distilled or deionized water rather than tap water to prevent mineral deposits from forming inside your radiator. If you are switching to G40 from a different coolant type (like older green or blue formulas), a full system flush is necessary to ensure the internal corrosion inhibitors can bond properly to the metal surfaces.
