FWGC 8516R Alternator

Overview

This alternator is built for Ford Mustang charging-system service with a 135-amp output and a 12-volt electrical system. Part number 8516R is engineered to supply the power needed for modern vehicle electrical demands while using proprietary components and processes for durability.

Key Features

• 135-amp alternator for steady charging output
• 12-volt unit with internal voltage regulation
• Internal fan design for integrated cooling
• Clockwise rotation with a serpentine belt pulley
• Decoupled clutch pulley included for smoother operation
• 6-groove pulley configuration

Detailed Description

Part number 8516R is a Ford-family alternator designed for 2005-2008 Ford Mustang applications. It uses an internal regulator, internal fan, and a serpentine belt drive with a 6-groove pulley to match the original charging-system layout. The 135-amp rating supports vehicles with higher electrical loads, including accessories and onboard electronics that place greater demand on the charging system. This alternator cross-references Anchor 8516 for the same application.

Common Issues It May Solve

• Low battery charging or repeated battery drain
• Dim lights caused by weak charging output
• Battery warning light related to alternator output
• Charging instability from a worn internal regulator
• Noise or belt drive issues tied to alternator pulley wear

Installation Notes

Verify pulley type, rotation direction, amperage rating, and electrical connector match before installation. Confirm fitment for 2005-2008 Ford Mustang, N/A, and compare the removed unit to part number 8516R to ensure the correct charging-system configuration.
