  Exhaust Manifold Nut, Manifold Nut, Pre-Converter Nut, Nut

• Description:

  This is a genuine Ford exhaust manifold-to-converter nut, the nut Ford catalogs as Manifold With Converter Nut and also as an Exhaust Manifold Nut, paired with exhaust manifold stud W704474-S437. Documented applications include 2.0L, 2.3L, and 2.5L four-cylinder engines, including hybrid and plug-in variants, used in Bronco, Explorer, Ranger, Continental, MKX, Zephyr, Mariner, and Milan, so this listing should be treated as a multi-vehicle service nut. The nut carries the clamp load that seals the manifold-to-converter flange through repeated heat cycling. Ford specifies this nut cannot be reused once removed; the locking feature is spent after first use, so a fresh nut is required whenever the joint is opened. A loose, corroded, or backed-off nut causes a flange leak that produces a ticking or roaring exhaust noise and a failed emissions check. Confirm the exhaust manifold hardware callout for your engine against your VIN before ordering so the nut matches your stud and the joint you are servicing. This is a multi-year service part that fits across the model years of the listed Ford applications.

• Notes: Part cannot be reused/reinstalled.
