  Engine Mount Cross-Member Bolt, Bolt

• Description:

  This is a Ford bolt listed under base number W709637 (catalog base HB4) and finish code S439, roughly an M10 by 70mm size, used at the engine cross-member and powertrain mount. Dealer catalogs name it as a bolt, a cross-member mount bolt, or an engine mount bolt. Representative applications include Transit with the 3.2L and 3.5L engines; these are examples rather than a complete fitment list. The bolt clamps the cross-member or mount so the powertrain stays located against torque reaction and road loads. This is a single-use fastener that Ford specifies cannot be reused or reinstalled, so it should be replaced rather than refitted. A loose, stretched, or missing bolt allows the mount to shift, which shows up as a clunk on acceleration, excess engine movement, or driveline vibration. Because this fastener carries structural loads and its grade, length, and thread must match the original, confirm this bolt against your VIN or a Ford parts diagram 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.
