Just top it off with water, it's fine." We've all heard it, and maybe we've all done it in an emergency. But using plain tap water as a permanent solution is a slow death sentence for your car's cooling system.

Tap water is full of minerals like calcium and magnesium. Under high heat, these minerals separate and form "scale" inside your radiator tubes-just like the white crust inside your kitchen kettle. This scale blocks the flow of fluid, causing your engine to overheat.

Water naturally oxidizes metal. Without the "Antirust" inhibitors found in Concept Radiator Coolant, your iron engine block and metal radiator parts will begin to rust within days. This rust flakes off and acts like sandpaper, destroying your water pump.

The Solution: Our pre-mixed coolants are made with demineralized water and the perfect balance of additives. They are ready to pour and guarantee zero scale buildup. Treat your car right-ditch the tap water today.
