Antifreeze & Coolant Concentrate

Best Antifreeze Coolant Concentrate

Zerex Dex-Cool Antifreeze Coolant Concentrate is a high-performance orange coolant designed to provide dependable protection for compatible automotive and truck cooling systems. This concentrated formula delivers freeze and anti-boil protection while helping maintain reliable engine cooling performance in demanding conditions.

Powered by Organic Acid Technology, Zerex Dex-Cool helps resist rust, scale, and corrosion while protecting cooling system metals, including aluminum. Its advanced additives are formulated to help protect against leaks without harming gaskets, hoses, plastics, or the original vehicle finish.

Because this is a concentrate, it should be mixed with clean tap water or demineralized water before use. A 50/50 mixture provides protection from approximately -34°F to 265°F. A 60/40 mixture can provide protection from approximately -62°F to 270°F, while a 70/30 mixture provides protection from approximately -84°F to 267°F. Always follow the vehicle manufacturer’s recommended coolant concentration.

Zerex Dex-Cool also offers a 5-year/150,000-mile guarantee against engine failure caused by freeze-ups or boil-overs when used according to applicable recommendations. The formula is batch-tested in the laboratory and fleet-tested in real-world conditions to help support consistent performance and maximize engine life.

The coolant contains 30–50 ppm of denatonium benzoate. The 1-gallon concentrate container provides a convenient option for coolant replacement, maintenance, and properly prepared cooling system refills.

Before using any antifreeze or coolant, verify that Dex-Cool is specified for your vehicle and follow the owner’s manual for proper coolant type, mixture ratio, and service procedures.
