Product Details

Part number 44094HD is a Gates heavy-duty engine water pump engineered for vehicles that rely on accessory-belt drive rather than timing-belt drive. Gates states that each new pump is built from premium alloy materials and undergoes seal and bearing function testing, along with leakage testing of the casting and assembled unit. This makes the 44094HD a strong service replacement when you need a direct-fit cooling component for Ford F-150, Chevrolet Silverado, and other heavy-duty truck applications that use this configuration.

This part cross-references Airtex AW2063 and Four Seasons 44094 for the same application.

Common Problems This Part Can Address

• Coolant leaks from a worn pump seal or casting surface
• Overheating caused by reduced coolant circulation
• Bearing noise from a failing water pump assembly
• Impeller wear that lowers coolant flow
• Service issues on accessory-belt-driven cooling systems

Installation Notes and Tips

Confirm pulley alignment, outlet orientation, and accessory-belt routing before installation. Inspect the belt, hoses, thermostat, and cooling passages at the same time so the new pump is not installed into a contaminated or restricted system. Use the correct coolant mixture, bleed air from the system, and verify there are no leaks after warm-up.

Quality Assurance

Gates Heavy-Duty Water Pumps are built for durable service and verified through functional testing of seals and bearings plus leakage testing of the casting and assembled pump. The 44094HD is intended to deliver OE-quality fit for the specified application.
