Show original supplier description
The FlowKooler 1650CI Hi-Flow Water Pump is engineered to combat overheating issues in Small Block Ford, Lincoln, and Mercury engines from 1970-1987. This aluminum pump body houses a 16-blade CNC machined billet impeller, featuring an increased vane count and reduced clearance between the impeller and the pump housing. This design results in significantly greater flow rates, higher head pressure, and a more efficient cooling system operation, helping to reduce engine temperatures by increasing opportunities for heat to dissipate. The impeller itself is treated with a Type II Class II military-grade surface coating, providing robust protection against corrosive fluids. The pump is designed for clockwise rotation and features a 5-13/16" fan hub working height. Notably, the lower radiator hose connection exits on the left side, which is the driver's side. Included with the water pump are mounting gaskets and a rubber heater hose adapter, along with an installation sheet and a FlowKooler decal. This water pump is compatible with a wide range of Ford, Lincoln, and Mercury models equipped with 302 (5.0L) and 351W (5.8L) V8 engines within the specified year ranges, including various Bronco, E-Series vans, F-Series trucks, and numerous car models.
