• Description:

  The W701548-S437 is a genuine Ford engine plug built on the 6026 base, a press-fit core or expansion plug that seals a machining or coolant passage in the engine block or head. Dealer catalogs carry it under the dominant name Engine Plug, with no separate functional alias on the diagram. Documented sample applications where this exact service number is cataloged include the Ford Explorer, F-150 and Ranger and the Lincoln Continental, MKX and Navigator, along with the Mercury Mariner and Milan; treat those as representative examples rather than a complete vehicle list, because Ford reuses one engine plug across many engines and model years and does not publish a single finite fitment chart for it. The plug presses into a cast bore to seal the coolant jacket or a core hole left from casting, and is intended to yield before the block if coolant freezes, providing a controlled failure point. It is installed once and driven out when serviced, so a fresh plug and the proper sealer are used on reassembly rather than reusing the old one. A corroded or weeping core plug causes coolant loss and overheating, and a buyer doing a cooling-system or engine refresh is often replacing these as a set. Because the suffix code denotes a specific diameter and depth, confirm fit for your exact vehicle by VIN before ordering rather than relying on the sample applications above.

• Applications: 2.0L. 2.5L. 2.3L.
