Application Details

Compatible with 1999-2003 Ford F-150, standard 130 amp applications, and 2004 Ford F-150 Heritage, standard 130 amp applications. The WAI 8251N alternator is built to match the electrical output and mounting style used in these Ford truck charging systems. This part cross-references 1L3T-10300-AB and XL3Z-10346-AA for the same application.

What This Alternator Helps Address

• Battery warning lights caused by weak charging output
• Dim headlights or unstable accessory performance
• Charging-system voltage drop under electrical load
• Alternator noise or failure from worn internal components
• Starting issues related to insufficient battery recharge

Installation Notes and Tips

Verify pulley groove count, belt type, rotation direction, and amperage rating before installation. This alternator uses an internal regulator and an 8-groove serpentine pulley, so the replacement should match the vehicle’s original charging-system configuration. Confirm fitment against the vehicle’s year, model, and standard 130 amp application before service.
