VP Cool Down™ Gas & Diesel Coolant Additive

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.
