• Description:

  This is a genuine Ford exhaust manifold stud, a high-temperature threaded stud built on the HT1 base, sized in the range of about M8 by 17.5 up to M8 by 36 millimeters, used to mount the exhaust manifold on Ford diesel engines. Ford dealer catalogs list it as an Exhaust Manifold Stud and Manifold Stud, and this part supersedes the earlier numbers 2W9Z-9K492-AA and W714851-S900. It threads into the cylinder head and provides a fixed shoulder so a nut can clamp the manifold firmly in place under the high heat and constant thermal cycling of the exhaust system. You will find it used on Ford Super Duty trucks including F-250, F-350, F-450, and F-550 Super Duty with the 6.7L Power Stroke diesel engine, in left and right positions, with applications spanning a broad range of model years. These are representative examples rather than a complete list. A corroded, stripped, or broken exhaust manifold stud lets the manifold loosen, which causes exhaust leaks, a ticking or hissing noise that is louder when cold, and over time a warped sealing surface. Because this is a high-temperature fastener that is commonly seized or broken, it is typically replaced as part of manifold service, and the retaining nut must be torqued to the Ford specification. Confirm the correct stud for your specific vehicle and engine against your VIN before ordering, since diesel exhaust hardware varies by application.
