Detailed Description

WAI 8442N alternator is engineered for Ford charging systems that require dependable output and OE-style fitment. This unit includes the pulley and uses a serpentine belt drive with clockwise rotation, making it a direct replacement choice for 2005-2007 Ford Five Hundred, 2005-2007 Ford Freestyle without auxiliary A/C, and 2005-2007 Mercury Montego. The WAI 8442N also cross-references Anchor 8442 for the same application.

Built as a new alternator rather than a remanufactured unit, this part uses proprietary components and manufacturing processes to support long service life and consistent performance. Search terms such as Ford Five Hundred alternator 130 amp, Mercury Montego alternator replacement, and 2005-2007 Ford Freestyle alternator with pulley all point to this application.

What This Alternator Helps Address

• Battery warning light caused by low charging output
• Dim headlights or unstable electrical performance
• Charging issues after alternator wear or failure
• Accessory power loss from insufficient amperage
• Noise or belt-drive concerns tied to a failing alternator assembly

Installation Notes and Tips

• Verify the vehicle uses a 12-volt system with clockwise alternator rotation.
• Confirm the 6-groove serpentine belt configuration before installation.
• Check that the vehicle matches the listed Ford Five Hundred, Ford Freestyle without auxiliary A/C, or Mercury Montego fitment.
• Inspect the belt, tensioner, and charging connections during alternator replacement.
