The Detroit Diesel Genuine Coolant Pump (EA4722002801) for Freightliner Cascadia DD15 engines is the OEM water pump. Using a genuine Detroit Diesel pump ensures exact flow rates, bearing specifications, and seal compatibility with the DD15 cooling system. A failing water pump causes coolant leaks from the pump housing, engine overheating, and eventual head gasket failure if not addressed. Genuine OEM parts maintain powertrain warranty compliance on newer Cascadia models.

A: Fits Freightliner Cascadia trucks with Detroit Diesel DD15 engines. Genuine OEM part number EA4722002801.
