FlowKooler 1622: FlowKooler Hi-Flow Mechanical Water Pumps

FlowKooler 1622: Water Pump, Mechanical, High-Volume, Iron, Natural, Pontiac, 389/400, Each - FlowKooler Hi-Flow mechanical water pumps resolve low-speed heating problems by doubling flow rates at low rpm and idle. CNC precision-machined impellers feature larger diameters, increased vane count, tighter clearances, shrouding, and porting. These unique design features help drop engine temperatures by up to 30 degrees, increase the block pressure to prevent hot spots on cylinder walls, and stop the formation of steam pockets in the block, all while delaying the onset of cavitation at higher rpm. FlowKooler Hi-Flow mechanical water pump impellers are protected from electrolysis and corrosion with a military-grade Type II Class II anodized surface coating. From 0-3,000 rpm nothing beats a FlowKooler! FlowKooler. 1622 fits these applications: PONTIAC 6.6L/400 Pontiac V8.
