The US4081 part number is also referenced by Airtex AW4081 and Gates 44023.

What It Helps Fix

• Coolant leaks from a worn water pump housing or seal area
• Overheating caused by reduced coolant circulation
• Noise from a failing pump bearing or impeller assembly
• Temperature fluctuation during normal engine operation
• Cooling system service needs on high-mileage Ford vans and trucks

Installation Notes and Tips

Before installation, inspect the belt drive, hoses, thermostat, and coolant condition so the new pump is not installed into a contaminated or restricted cooling system. Clean the mounting surface thoroughly and follow the vehicle service procedure for torque sequence, coolant refill, and air bleeding. Verify the application by year, make, and model before ordering US4081.

Quality Assurance

US Motor Works supplies replacement cooling components for service applications, and this pump includes installation sealing devices to support sealing during fitment. Confirm the vehicle match against the listed Ford applications before installation.
