• Alternator bearing noise, pulley wear, or charging failure
• Need for an OE-style remanufactured replacement for a Ford 3G system

Installation Notes

Verify the existing alternator matches the 3G series, 130-amp rating, clockwise rotation, 8-groove serpentine pulley, and 10 o’clock plug position before installation. Confirm belt alignment, connector fit, and charging-system condition during replacement. Inspect the battery, belt, and wiring before starting the vehicle after installation.
