7.3 Powerstroke Water Pump | Atlas 146-0001

Replace a leaking or noisy late 7.3 water pump with a new Atlas Diesel unit. Atlas 146-0001 is a replacement water pump for 1999–2003 Ford 7.3L Powerstroke engines. It restores coolant flow through the engine and radiator and is sold as a complete install-ready pump. Some one-piece cast-body applications need the included inlet elbow. A worn pump can cause overheating, coolant loss, or noise from the front of the engine.
