Alternator for Ford Mustang

This WAI alternator, part number 11656N, is a 100% new replacement built for charging-system performance. It is engineered to deliver the amperage needed for modern electrical loads while using proprietary components and processes for consistent service life.

Key Features

  • 150-amp output for stable charging performance.
  • 100% new construction, not remanufactured.
  • Internal fan and internal regulator design.
  • Clockwise rotation with a 6-groove serpentine pulley.
  • Family: DENSO.

Detailed Description

Part number 11656N is a WAI alternator designed for Ford Mustang applications that require a Denso IR/IF, 150A unit. The internal regulator and internal fan support compact alternator packaging, while the included pulley and serpentine belt configuration match common OE charging-system layouts. For buyers replacing a worn charging unit on a Ford Mustang, this alternator provides a direct-fit electrical replacement for the specified application.

WAI builds this alternator as a new unit rather than a remanufactured assembly, using proprietary components and manufacturing processes to support long-term performance. This part cross-references Monroe Shocks & Struts (e.g., 11656) for the same application.

What It Is Used For

  • Low charging output from a failing alternator.
  • Battery warning light caused by charging-system faults.
  • Electrical instability from insufficient amperage supply.
  • Belt-driven charging replacement when the original unit wears out.

Installation Notes and Tips

Fits 2011-2014 Ford Mustang, N/A. Confirm the Denso IR/IF, 150A application, clockwise rotation, 6-groove serpentine pulley, and internal regulator before installation. Verify belt alignment and electrical connections during replacement.

Quality Assurance

WAI states this alternator is 100% new and manufactured with proprietary components and processes to support maximum life and performance.
