Quick facts
- Part: Gates 41176HD water pump

- Fits: the 1999-2004 Freightliner MT45 6-cylinder 5.9L and other vehicles
- Material: Cast iron housing, stamped steel impeller
- Condition: New
Coolant leaking at the pump, a grinding or whining noise from the bearings or an engine that runs hot can mean the water pump is worn. Before you replace it, rule out a low coolant level, a slipping drive belt and a thermostat that is not opening, since each of those can also run an engine hot. Each engine takes one pump.
Fits
The list also includes the 1999-2003 Freightliner MT55 6-cylinder 5.9L and the 2005-2007 Kenworth T300 6-cylinder 5.9L.
