• Description:

  The W701617-S437 is a genuine Ford bolt, an M6 by 77mm fastener used to secure the engine water manifold, with dealer catalogs noting it is included with the water manifold and citing left-front and right-front positions. Catalog descriptions tie it to 6.7L diesel applications and to Police Interceptor configurations, with coverage spanning many model years; treat those as representative examples rather than a complete vehicle list, because Ford reuses one manifold bolt across related engines and model years and does not publish a single finite fitment chart for it. The water manifold routes coolant across the engine, and these bolts clamp it and its seals to the block or heads at the specified torque so the cooling joint stays sealed. When one is loose, stretched, corroded or missing, the manifold can weep coolant, lose clamp load at the gasket, or loosen under heat cycling and vibration, and a buyer servicing the cooling system on a 6.7L diesel often replaces the full group of long M6 bolts. Replacing them with the correct genuine bolts restores even clamp load on the manifold. Because the suffix code denotes a specific thread size, length, grade and finish, confirm fit for your exact vehicle by VIN before ordering rather than relying on the sample applications above.

• Notes: Included with water manifold.
