Coolant Additive Neutralizes Hard Water Corrosion

Protect your engine block, cylinder heads, water pump and radiator from the adverse effects of using modern coolants and traditional antifreeze that are mixed with non-distilled water. Driven Coolant System Protector (CSP) neutralizes the minerals and impurities in hard water, regular tap water, and well water that is commonly used when adding or topping off your cooling system fluid. Driven CSP will keep your cooling system passages clean and improve water pump lubrication for long-term, durable performance.
