    Abstract: An improved radiator mounting and cooling system for use in automobiles allows multiple components to be incorporated into the same unit, limiting the need for accessories to be mounted to inner fenders or firewall. 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.
