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 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 Type II Class II Military Grade anodized surface coating. From 0-3,000 rpm…nothing beats a FlowKooler!

Form Fit and Function

Summit RacingSummit Racing Verified Purchase

Pump fit perfect, came with 2 gaskets and clearance with backplate was exceptional. So far cooling performance is improved over stock cast impeller pump. Time will tell but so far this pump is a winner.
