Coolants, Antifreeze & Cooling System Fluids

Engine coolant is the fluid that circulates through the radiator, engine block, and heater core to regulate engine operating temperature. The right coolant provides freeze protection, boil-over protection, corrosion inhibition, and water pump lubrication. Using the correct coolant type for your vehicle's metallurgy and gasket materials is essential for long-term cooling system health.

OneFastShop carries coolants and antifreeze including conventional green coolant, extended-life OAT coolant, hybrid OAT coolant, European-spec coolant, Asian-spec coolant, waterless coolant, coolant additives, and cooling system flush products for cars, trucks, SUVs, and performance applications.

Every coolant at OneFastShop ships brand-new and factory-sealed. Whether you're performing a routine coolant flush, switching to a waterless coolant for track use, or topping off with the correct spec for your European or Asian vehicle, OneFastShop has the right coolant. Shop the full coolants collection today.
