• Description:

  This is a genuine Ford W714841-S437 engine coolant thermostat housing bolt, a threaded fastener that secures the thermostat housing or coolant outlet to the engine. It is documented on Ford F-150 and Ford Explorer applications across a span of recent model years, covering 3.5L and 3.7L engine builds, and is shared with related platforms. The catalog name is Engine Coolant Thermostat Housing Bolt. Because the joint sits under coolant pressure and constant heat cycling, correct and even clamp load matters. A loose, missing, or unevenly torqued bolt produces a coolant leak at the housing, coolant loss, steam or sweet smell, and eventual overheating if the leak is severe. The bolt clamps the housing and its seal or gasket against the engine so the sealed joint holds pressure. It is a service fastener routinely renewed when the thermostat or housing is replaced, since corrosion and heat cycling can weaken a reused bolt. Always torque it to the published specification in the correct sequence on reassembly. Confirm the thread size and fitment against your VIN through a Ford parts catalog before ordering to be sure it matches your thermostat housing, engine and model year.
