• Description:

  This is a genuine Ford W503278-S437 bolt, base part HB1, cataloged by Ford dealers as the water pump assembly bolt, an M6 x 27mm fastener used in left and right lower and inner positions, and Ford notes it is included with the water pump and with the thermostat housing. It is offered as a multi-vehicle part documented on models such as E-350, F-150 and Ranger, plus Lincoln Continental, MKS and Navigator and Mercury Milan and Sable, among others. The bolt secures the water pump or thermostat housing to the engine, holding that component sealed and located so coolant flow is contained. A loose, corroded or under-torqued bolt can cause a coolant leak, overheating or a loose component. Because the same fastener spans many applications, no single finite vehicle list is published; confirm position and fit for your specific vehicle by VIN before installing. Supplied as a genuine OEM Ford part built to original specification. This is a multi-year service part that fits across the model years of the listed Ford applications.

• Notes: Included with water pump. Included with thermostat housing.
