Ford 351C/351M/400 High-Flow Mechanical Water Pump - Black

• High-volume pump flow helps circulate coolant more efficiently through the radiator and engine passages

• 5.710 in. hub height and 0.625 in. pilot diameter help maintain proper pulley alignment and belt tracking

• 8-vane clockwise impeller design helps maintain steady coolant movement at varying engine speeds

• Powder-coated Aluminum housing finish adds corrosion resistance with a cleaner performance appearance

This Ford 351C, 351M, and 400 High-Flow Mechanical Water Pump is designed for Ford 335-series V8 engines. Featuring a high-volume 8-vane aluminum impeller, clockwise rotation, and driver-side inlet configuration, it helps improve coolant circulation while maintaining compatibility with many traditional Cleveland and Modified accessory drive systems.

Pulley Alignment
5/8 In. pilot diameter help position the pulley and fan drive during installation.

Inlet Configuration
This water pump uses a driver-side lower radiator hose inlet and is designed for compatible Ford 351C, 351M, and 400 cooling systems. Verify inlet location before ordering to ensure proper radiator hose routing and cooling system compatibility.

Impeller & Flow Design
The high-volume impeller setup helps move coolant steadily through the block, heads, and radiator circuit.

Installation Notes
Confirm gasket requirements, pulley alignment, and hose routing before final assembly.

What applications is this water pump compatible with?
This water pump is commonly used on Ford cars, trucks, street rods, and performance builds equipped with 351C, 351M, or 400 engines using a driver-side inlet cooling system. Verify cooling system and accessory-drive compatibility before installation.

Will this water pump fit my engine?
This water pump is designed for Ford 335-series V8 engines including 351 Cleveland (351C), 351 Modified (351M), and 400 applications. It features a driver-side lower radiator hose inlet and clockwise rotation. Verify inlet location, pulley alignment, and water pump dimensions before ordering.

What does a water pump do?
A water pump circulates coolant through the engine and radiator to help maintain proper operating temperature.

What material is this water pump made from?
This water pump is made from aluminum, which helps with durability and heat dissipation.

What type of impeller does this water pump use?
This water pump features an 8-vane cast aluminum anti-cavitation impeller designed to improve coolant flow and help maintain efficient cooling at varying engine speeds. TSP high-flow water pumps are designed to flow approximately 40% more coolant than many stock water pumps.

Does this water pump include a gasket?
Yes, this water pump includes a gasket for installation.

Is this water pump suitable for performance applications?
Yes, this water pump is designed to support performance and upgraded cooling systems.

Will this water pump help prevent overheating?
Yes, a properly functioning performance water pump can improve coolant circulation and help reduce overheating.

Is this a good upgrade from a stock water pump?
Yes, this water pump is a strong upgrade for improving cooling efficiency and reliability.

Do I need to verify rotation before installation?
Yes, water pump rotation must match your belt drive system to ensure proper coolant flow.

Can this water pump be used with aftermarket radiators?
Yes, this pump can be used with upgraded cooling systems when properly matched to the engine setup.

Does this fit a 289, 302, or 351W Windsor engine?
No. This water pump is designed for Ford 335-series engines including 351C, 351M, and 400 applications. Ford Windsor engines such as the 289, 302, and 351W use a different water pump and cooling system configuration.
