Thumbnail Filmstrip of 1994-2003 7.3L Powerstroke Water Pump Alliant AP63501 Images
The Alliant AP63501 is a water pump for a 7.3 Powerstroke. The gasket is in the box. Alliant crosses it to Ford F81Z-8501-ARM, F81Z-8501-CRM, and F6TZ-8501-AARM.
It is the replacement pump for a weep at the snout or a noisy bearing. Match the inlet on the pump you pull. An early OBS housing is not the late Super Duty housing. The late-style Atlas pump is 146-0001. The thermostat is Motorcraft F6TZ-8575-EA. The heater-hose nipple is F81Z-18599-AA.
