Product Details

Features

  • High-volume pump flow helps circulate coolant more efficiently through the radiator and engine passages
  • 5.625 in. hub height and 0.625 in. pilot diameter help maintain proper pulley alignment and belt tracking
  • 8-vane counter-clockwise impeller design helps maintain steady coolant movement at varying engine speeds
  • Polished Aluminum housing finish adds corrosion resistance with a cleaner performance appearance

Description

This Ford Small Block Windsor Reverse Rotation High-Flow Mechanical Water Pump is designed for 302 and 351W V8 engines using a serpentine accessory drive system. Featuring a high-volume 8-vane aluminum impeller, counter-clockwise rotation, and driver-side inlet configuration, it helps improve coolant circulation while maintaining compatibility with many late-model Windsor applications.

Pulley Alignment
5.625 in. hub height and 0.625 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. Verify the inlet location on your existing water pump and cooling system before ordering to ensure proper hose routing and compatibility.

Impeller & Flow Design
The 8-vane counter-clockwise high-volume impeller setup helps move coolant steadily through the block, heads, and radiator circuit.

Installation Notes
Confirm gasket included: yes, mounting hardware included: no, back housing included: yes before final assembly.

Q&A

What applications is this water pump compatible with?
This water pump is commonly used on Ford Small Block Windsor-powered cars, trucks, street rods, and performance builds utilizing a reverse-rotation serpentine accessory drive system. Reverse-rotation pumps are commonly found on many 1986–1993 Ford small block applications.


Will this water pump fit my engine?
This water pump is designed for Ford Small Block Windsor V8 engines including 302 and 351W applications. It features a reverse-rotation impeller and driver-side lower radiator hose inlet. Verify rotation requirements, inlet location, and pulley alignment 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 aluminum impeller designed to improve coolant flow and help maintain efficient cooling at varying engine speeds. The reverse-rotation design supports applications that require counter-clockwise water pump operation.


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.

What is a reverse-rotation water pump?
A reverse-rotation water pump is designed to spin counter-clockwise and is commonly used with serpentine belt systems. Installing a reverse-rotation pump in a standard-rotation application can reduce coolant circulation and lead to overheating. Always verify pump rotation before installation.
