• Direct OEM replacement: All ports, gear and mounting bosses align with the 2023 DD15 block; no bracket or hose modifications are required.
• Upgraded sealing: SiC seal and double ball bearings meet Detroit’s 500,000 mi durability target, resisting EGR-induced acidity and extended idling.
• New casting—no core return: Eliminates downtime tied to core credits and ensures 100% new components.
• Kit contents: Pump, Viton O-ring and torque-spec sheet. Reuse the original bolts; Detroit recommends 18 N·m (13 lb-ft) plus 60° on M8 fasteners.

This heavy-duty water pump restores factory coolant flow on 2023-up Freightliner Cascadia tractors powered by the latest Detroit DD15 engine. The cast-iron housing and steel impeller withstand high thermal loads, while the SiC seal prevents leaks under severe cycles. Supplied new and ready to install, the pump slots into the timing-gear train in under two hours and carries a one-year parts warranty.
