Product Description

Cool Down™ improves the performance of your coolant and is safe for all radiator systems — ideal for racing, street, RV and tow vehicle applications. It reduces cylinder head temperatures up to 75°F! Cool Down increases coolant flow for better heat transfer, lubricates all vital components and is approved by most race sanctioning bodies. One 16oz. bottle treats cooling systems of 12-20 quarts. For straight water applications, an additional 50% more Cool Down is recommended while diesel applications require twice the normal amount. Treatments last for one year or 30,000 miles, whichever comes first.
