VP Cool Down™ coolant additive is designed for gas and diesel engines and works with coolant or straight water systems. Its advanced formula reduces coolant surface tension for superior heat transfer and lowers engine temperatures by up to 30°F. Cylinder head temps can drop by as much as 75°F, helping to prevent overheating. Our coolant additive also lubricates vital components, including water pumps and seals, while safeguarding against corrosion and electrolysis of all metals, especially aluminum. It meets and exceeds ASTM D3306 specifications, making it the trusted choice for racing, street vehicles, RVs, and towing.
NOTE: Before using Cool Down for the first time, we recommend using Frosty Clean Cooling System Flush to optimize your cooling system's efficiency and maximize Cool Down's performance.

APPLICATIONS & RATIOS:
- Coolant Applications (12-20 quarts): One pint bottle treats 12-20 quarts. For coolant systems over 20 quarts, add one ounce of Cool Down for each additional quart.
- Straight Water Applications: For full corrosion protection, add 50% more Cool Down. Use reverse osmosis water labeled "Purified Drinking Water" for optimal results.
- Diesel Applications: For full protection of wet sleeve cylinder liners, add twice the amount.
- Powersport Applications: Use 2 oz per quart of coolant.
- Frequency: Add one pint every year or every 30,000 miles. After the 5th consecutive year, drain, flush, and refill the cooling system.
Can you mix this 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.
