VP RACING Cool Down Cool Down from VP RACING is an advanced coolant enhancer engineered to lower engine temperatures, improve flow, and protect critical components for peak performance and longevity. Lower temperatures: Reduces cylinder head temps by up to 75°F and overall coolant temperatures by as much as 30°F. Improved heat transfer: Increases coolant flow for more efficient dissipation of engine heat. Superior lubrication: Coats and lubricates vital components without the crystallization problems common to other additives. Aluminum protection: Formulated to protect sensitive aluminum alloys used in modern engines. OAT-compatible: Designed for use with today's new OAT-formula engine coolants. Meets industry standards: When mixed with filtered water, meets ASTM D3306 as a standalone engine coolant. Advanced surfactants: Contains multiple surfactants for unsurpassed temperature reduction and sustained performance. Ideal for high-performance and everyday applications, VP RACING Cool Down delivers reliable temperature control, enhanced flow, and component protection—helping engines run cooler and last longer.
