Zerex G05 Gold Coolant - 1 Gallon

Zerex G05 Gold Coolant - 1 Gallon

OEM-Approved HOAT Protection for Ford, Chrysler, and Diesel Engines

Ensure your cooling system operates with factory-level precision using Zerex G05. This gold-colored formula is specifically engineered to meet the rigorous requirements of Ford and Chrysler, as well as many European manufacturers. By utilizing a phosphate-free chemistry reinforced with nitrites, it provides superior protection against cylinder liner pitting and cavitation, which is critical for high-output and diesel engines. Whether you are performing a full system flush or a seasonal service, Zerex G05 offers the exact chemical profile needed to maintain engine health and prevent the formation of scale and deposits.

Available Variants:

- G05 Concentrate (ZXG051): 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.

- G05 50/50 Pre-Mix (ZXG05RU1): A ready-to-use solution pre-diluted with demineralized 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 HOAT Chemistry: Features the precise Hybrid Organic Acid Technology required by Ford, Chrysler, and Mercedes-Benz to ensure total compatibility with factory seals and gaskets.

- Nitrite-Enriched Formula: Provides an added layer of protection against cavitation and pitting in cylinder liners, making it an excellent choice for both performance street and heavy-duty diesel engines.

- Low Silicate, Phosphate-Free: Reduces the risk of hard water scale buildup while providing a long service life of up to 5 years or 150,000 miles.

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

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

Precision Tip: When using the Concentrate variant, always mix with distilled or deionized water rather than tap water to prevent mineral buildup. Avoid mixing G05 with traditional "Universal" or Dex-Cool fluids, as the chemical conflict can reduce the effectiveness of the corrosion inhibitors. For a thorough service, a full system flush is recommended.
