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!

Works on my blown 496

Summit RacingSummit Racing Verified Purchase

This product immediately dropped the temp on my 496 BBC with a 671 blower and 2x600 cfm carbs from 220 to 190 at idle. I couldn't be happier. My original pump was a good, name brand pump, but the Flowkooler is 30 degrees better, just like they say!

Great fit, finish, and operation

I installed this into a '71 chevy 402. The fit and finish was exceptional and performance wise it greatly lowered my average running temp. I was just cruising Woodward with 30000 other people and didn't have any overheating concerns. Very impressed. You get what you pay for.

Couldn't really tell much difference in this pump and the edelbrock. The heating up problem in summer traffic has slowed but is still something that has to be watched with this pump too so it didn't completely solve my problems. ...read more
