FlowKooler Water Pump, 302ci 80-86 Ford Bronco, 351ci 83-87 Ford Bronco SKU: FK1650

FlowKooler Water Pump | 80–86 Bronco 302ci | 83–87 Bronco 351ci

Designed specifically for 1980–86 Ford Broncos with 302ci engines and 1983–87 Broncos with 351ci Windsor engines, the FlowKooler 1650 high-flow water pump addresses low-speed overheating issues common in off-road and heavy-duty applications. Its CNC-machined billet aluminum impeller features an increased vane count and reduced clearance, effectively doubling coolant flow at idle and low RPMs. This design enhances heat dissipation, reduces engine temperatures by up to 30°F, and prevents the formation of steam pockets, ensuring consistent performance during demanding conditions.

Combat low-speed overheating in your 180-87 Bronco with the FlowKooler water pump - it doubles coolant flow and keeps your engine running cool under pressure.

es at low rpm and idle (which is perfect for off-roading). 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.

Impellers are protected from electrolysis and corrosion with a Type II Class II Military Grade anodized surface coating. From 0-3,000 rpms…Nothing Beats a FlowKooler!

Independent testing by a major engineering university and the world's largest automotive manufacturer has proven FlowKooler pumps outperform all other makes at low speeds. One more added bonus is that the aluminum water pump weighs considerably less than its cast iron counterpart.

We recommend using a high flow thermostat in conjunction with this pump.
