The Seidel Diesel Group is pleased to announce an update to Alliant Power’s AP63505 Water Pump for the Ford® 6.7L Power Stroke® application listed in the table below. Alliant Power introduced AP63505 and AP63506 Water Pumps that utilized a water jacket housing which differs by application. It has
been determined the water pumps tend to fail more than the housing. To address this issue Alliant Power is now offering the water pump separate from the housing. This water pump is for use on both the single and dual alternator models as the secondary water pump.
NPA 40/15 (AP63505 Water Pump) and NPA 43/15 (AP63506 Water Pump) will be obsolete due to this NPA.
