Keep coolant circulating through your engine with the Airtex Engine Water Pump AW6344. It fits many trucks powered by the L6-14.9L engine, including the 2011-2015 Western Star 4900EX 14.9L and 2010-2015 Freightliner Cascadia 14.9L. See the Buyer's Guide tab for the full list.
The pump draws coolant through the engine and cooling system, using its impeller to keep flow moving and help the engine hold its normal operating temperature. If a worn, leaking, or seized water pump is the cause of overheating or coolant loss, this replaces it.
- Cast iron housing and cast iron impeller with a 6-vane impeller and standard impeller rotation.
- Serpentine belt drive with the pulley included; the fan clutch is not included.
- 7 mounting holes, plus heavy-duty unitized bearings, pressed-on hubs, precision-machined housings, unitized seals and set impeller clearance.
- 100% factory tested, validated for fit, form, and function, and built to OE-level tolerances; application-specific design for correct fit and operation.
