• Description:

  This is an engine mount bolt, base part HB1, used to fasten an engine support insulator to its frame bracket. The dominant catalog name is motor mount bolt, appearing also as engine mount-to-frame bolt and insulator bolt on related diagrams. Documented applications include Expedition, F-150, and Navigator installations, listed here as examples and not a complete vehicle list. This is a single-use fastener that Ford specifies cannot be reused or reinstalled, so it should be replaced rather than refitted whenever the mount is disturbed. The bolt carries powertrain weight and reacts engine torque, so a loose, stretched, or reused bolt lets the engine shift under load, which a buyer notices as a clunk on acceleration or shifting and driveline vibration. Because it is a load-bearing powertrain fastener it must be torqued to the published specification. Ford does not publish one finite vehicle list for this universal fastener, so confirm fit for your specific vehicle by VIN before ordering. This is a multi-year service part that fits across the model years of the listed Ford applications.

• Notes: Part cannot be reused/reinstalled.
