A circulating vortex of air is pulled through a front grill and vortex tubes disposed through sides of the radiator system to improve cooling efficiency. An outer shroud protects interior components and creates a sealed core cavity allowing air to only enter through vortex tubes and front grill and exit through a rear grill. A self-circulating cooling system provides additional cooling of coolant. A fan system pulls around 5000 CFM of air through the core cavity. An optional secondary coolant pumping system allows coolant to be pumped when needed. A control system controls activation of the fan system and secondary coolant pumping system based on signals from sensors.
