WAI 8448N Alternator

Overview

WAI alternator part number 8448N is a new, not remanufactured charging component built to deliver 135 amps for modern electrical loads. It is a direct-fit style replacement for select Ford and Mercury applications, including Ford Explorer and Mercury Mountaineer models.

Key Features

• 135-amp output for stable charging performance.
• 100% new unit with proprietary components and manufacturing processes.
• Internal regulator and internal fan design.
• Clockwise rotation with a 6-groove serpentine pulley.
• Pulley included for a complete alternator assembly.

Detailed Description

WAI part number 8448N is engineered for vehicles that need dependable charging capacity from an alternator built as a new unit rather than a remanufactured core. The internal regulator, internal fan, and clockwise rotation support OE-style electrical system operation, while the 6-groove serpentine pulley matches the belt drive used in the listed applications. This alternator is a practical replacement for Ford Explorer and Mercury Mountaineer charging-system service, and it also cross-references BBB Industries 8448 for the same application. The WAI 8448N is also listed for Ford Explorer Sport Trac models with 130-amp notes in the fitment data.

What It Helps Solve

• Low charging output from a worn alternator.
• Battery warning lights caused by charging-system failure.
• Electrical instability under accessory load.
• Noise or pulley-related alternator issues.

Installation Notes

Verify belt type, pulley groove count, rotation direction, and amperage rating before installation. Confirm the vehicle uses the listed serpentine belt setup and compare the original unit to WAI 8448N for connector and mounting match. Fitment includes 2006-2008 Ford Explorer, 2007-2008 Ford Explorer Sport Trac, and 2006-2008 Mercury Mountaineer.

Quality Assurance

WAI states this alternator is 100% new and built with proprietary components and processes to support long service life and consistent performance.
