Flowkooler High Flow pump 1747 for the Jeep Cherokee, Comanche and Wagoneer has a CNC machined billet impeller designed with an increased vane count and a reduced impeller clearance to achieve greater flow rates, higher block pressure. A Type II Class II military grade anodize surface coating protects against corrosive fluids. PLEASE inspect the fan hub and check applications below as the 1747 and 1748 are frequently mis-ordered. We developed this hi flow pump because Jeeps tend to overheat in stop and go traffic and on the trail. Tight engine space and limited airflow plague the Jeep cooling system but it has been proven time and time again that reducing the cycle time between the heat source and the heat sink drops engine temperatures for slow speed rock crawling and stop and go traffic. From 0-3,300 RPM…Nothing Beats a FlowKooler!
