Be Cool’s new Circle Track product line offers 29 radiators in four distinctly different radiator configurations. Knowledgeable racers can choose from either single or dual pass tank designs with either slip-on or AN-style inlets. These new crossflow radiators feature a performance- grade, dual 1’’ core with “form-folded” and tapered tanks. With the form-folded design the filler neck is placed horizontally for easy filling and to help insure the cooling system is completely full. The new models are available in either single or dual pass designs as well as with either traditional slip-on or AN thread inlet openings. The AN-threaded inlet opening provides the ultimate in secure upper hose attachment. In all models the lower hose outlet is a slip-on design. It is located higher on the tank for proper fitment in the chassis and tilted upwards for easier lower hose installation or removal. Additionally, all versions of the Be Cool Circle Track Hard Core Racing Radiators are constructed with “twist resist” upper and lower protective aluminum core rails for extra rigidity as well as a billet Filler neck with high-capacity overflow tube.
