VP Racing Engine Coolant Additive
Race-Proven Cooling Chemistry from VP Racing
When heat is the enemy of performance, VP Racing brings the same engineering discipline that has powered motorsports champions since 1975 to your cooling system. Engine coolant additives are often overlooked in routine maintenance, yet the difference between a well-treated cooling system and a neglected one can mean the difference between a podium finish and a blown head gasket on a hot summer tow. VP Racing's approach to coolant chemistry is rooted in decades of race-track data — the same technology trusted in NHRA drag racing, off-road desert racing, and road courses worldwide.
VP Cool Down™ — The Flagship Coolant Additive
The centerpiece of VP Racing's engine coolant additive lineup is the VP Cool Down™. This advanced formula is engineered for both gasoline and diesel engines and works seamlessly with coolant or straight-water cooling systems. Its core mechanism targets one of the primary limitations of conventional coolants: surface tension. By reducing coolant surface tension, Cool Down enhances fluid contact with hot metal surfaces for superior heat transfer.
- Up to 30°F reduction in overall coolant temperatures
- Up to 75°F reduction in cylinder head temperatures, helping prevent overheating
- Lubricates vital components including water pumps and seals
- Guards against corrosion and electrolysis across all metals, with particular protection for sensitive aluminum alloys
- Contains multiple surfactants for unsurpassed temperature reduction
- Formulated for compatibility with modern OAT and HOAT-formula engine coolants
- Meets and exceeds ASTM D3306 specifications
- Approved by most race sanctioning bodies
A single 16 oz. bottle of Cool Down treats cooling systems ranging from 12 to 20 quarts, and each treatment is rated to last one year or 30,000 miles — whichever comes first. For powersports, RV, and tow vehicle applications, dosing guidelines ensure the formula is equally effective across a wide range of system sizes.
Why VP Racing Stands Apart in Coolant Chemistry
What separates VP Racing's coolant additives from generic store-shelf alternatives is pedigree. VP Racing has spent over 50 years developing, formulating, and testing performance chemicals under the harshest conditions imaginable — from Baja desert heat to the demanding thermal cycles of NHRA Pro Stock engines. That same expertise is directly applied to their engine coolant additive line. Every product is made in the USA and engineered to complement VP's broader cooling ecosystem, including their Stay Frosty® Hi-Performance coolants, making it easy to build a complete, race-validated thermal management strategy for your vehicle.
Whether you're managing heat in a high-output modified engine, protecting an aluminum-heavy modern turbocharged platform, or simply looking to extend the service life of a work truck or tow rig, VP Racing's coolant additives offer a straightforward, proven upgrade to your existing system.
