Description
Product Description
We formulate Cool Down™ coolant additive not just for gasoline engines. It also works great as a diesel coolant additive. It improves the performance of coolant and is safe for all radiator systems. It's ideal for racing, street, RV and tow vehicle applications. Our product reduces cylinder head temperatures up to 75°F and decreases engine temperature up to 30°F! Cool Down increases coolant flow for better heat transfer. Furthermore, it 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, we recommend adding 50% more Cool Down. Additionally, diesel applications require twice the normal amount of our coolant additive.
Treatments last for one year or 30,000 miles, whichever comes first. We do suggest changing your coolant every 2 years. When using as a diesel coolant additive, we recommend using twice the suggested amount for full protection of wet sleeve cylinder liners. Another key point is that you should use 2 oz. of Cool Down for every quart of coolant for Powersports applications.
Cool Down is a great compliment to our Stay Frosty® Glycol-free Race-Ready racing coolant as well as Stay Frosty® Hi-Performance engine coolant.
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 Cool Down™ work in cold weather climates?
If used as directed, it shouldn’t disrupt the freeze protection provided by traditional antifreeze that contains glycol.
