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.

Frequently Asked Questions:
Can you mix this coolant additive with antifreeze?
Yes, you can. Cool Down works great with antifreeze. It is formulated for use with today’s OAT and HOAT-formula engine coolants. We recommend changing your coolant every 2 years.
How do I use Cool Down™?
Just open the bottle and add the contents straight into the radiator or coolant reservoir. If you have access to a radiator cap, pouring Cool Down directly into the radiator is the preferred method. One 16 oz. bottle will treat cooling systems of 12-20 quarts.
Will your coolant additive work in cold weather climates?
If used as directed, it shouldn’t disrupt the freeze protection provided by traditional antifreeze that contains glycol.
