WaterWetter Radiator Fluid
Keep Your Engine Running Cooler. Red Line WaterWetter Radiator Fluid has been scientifically formulated to reduce the operating temperature of your engine by up to 20 degrees than standard coolant alone, and as everyone knows cooler engine temperatures equal more horsepower.

Corrosion Resistant. Red Line WaterWetter has been designed for use in all modern cooling systems to prevent the formation of scale deposits in the radiator for optimal coolant flow while providing additional protection against rust and corrosion that could potentially cause leaks, overheating, and other cooling system failures.

Quantity/Measurement. For street vehicles requiring freeze protection add one 12 oz bottle to 3-5 gallons (12-20 quarts) of 50/50 water antifreeze mix. Vehicles with larger cooling systems should use two bottles. Smaller cooling systems should use 1oz (3 to 4 capfuls) per quart.

Application. Red Line WaterWetter Radiator Coolant Additive is safe for use in all 1979-2022 Mustangs, including LX, V6, GT, Bullitt, Mach 1, SVT Cobra, BOSS and Shelby GT500 models. Sold individually.
