Keep coolant circulating through your heavy-duty diesel with the Airtex Engine Water Pump AW6344. It fits a wide range of Class 8 trucks powered by the L6-14.9L engine, including the 2010-2015 Freightliner Cascadia, 2011-2015 Freightliner Coronado, 2008-2015 Peterbilt 367, 388 and 389, and 2011-2015 Western Star 4900EX — see the Buyer's Guide tab for the full list of 29 applications.
The pump draws coolant through the engine and cooling system, using its impeller to keep flow moving so the engine holds 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 and back housing are 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 and built to meet or exceed Original Equipment specifications; application-specific design for correct fit and operation.
