COOL DOWN 16OZ
SKU2085
Thanks to advanced wetting agents, VP Cool Down™ is the best engine coolant additive for reducing coolant surface tension. It delivers exceptional heat transfer in radiators and reduces nucleate boiling in cylinder heads.
Cool Down helps prevent overheating and lowers engine temps (by up to 30°F!). It lubricates all vital components, including water pumps and seals, and prevents corrosion and electrolysis of all metals, especially aluminum. Cool Down meets/exceeds ASTM D3306 specifications established by OEMs for engine coolant. It's ideal for use as a gas or diesel coolant additive and perfect for racing, street vehicles, RVs, & towing applications.
Take a look at what happened when Engine Labs put Cool Down to the test on a 2006 C6 Corvette.
- REDUCES ENGINE TEMPERATURES: Run up to 30˚F cooler and prevent overheating.
- ENHANCES PERFORMANCE: Cooler cylinder heads allow for advanced ignition timing and more power.
- PREVENTS CORROSION/ELECTROLYSIS: Protects high-dollar, sensitive aluminum radiators.
- LUBRICATES WATER PUMPS: Contains polymers that lubricate water pumps and seals.
- KEEPS SYSTEM CLEAN: Contains dispersants that prevent efficiency-robbing scale/deposit buildup.
- GREAT FOR STREET USE: High-compression engines, turbo engines, RVs, and tow vehicles.
- SAFE FOR TRACK USE: Does not contain glycol, which is prohibited by most racetracks.
DIRECTIONS:
- Cool the Engine: Make sure the engine is cool before removing the radiator cap.
- Add Cool Down: Pour Cool Down into the radiator. Please refer to the proper ratio below.
- Start the Engine: Turn on the engine and set the heater to high.
- Run for 10 Minutes: Let the engine run for 10 minutes to circulate the Cool Down coolant additive.
- Reminder: Keep at least 15% antifreeze in the cooling system for street-driven vehicles with A/C.
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.
