Product Details

Remy 23723 is a remanufactured alternator for Ford Mustang models from 2001 through 2004. It is built for vehicles that require a 105-amp capacity and is not compatible with Mustang applications rated below 105 amps. This alternator cross-references Ford OE numbers 1R3U-10300-AA and 1R3U-10300-AB for the same application.

The Premium Remanufactured line from Remy focuses on OE-style replacement parts that match the original charging-system layout, including internal regulation and the correct rotation direction. For shoppers searching for a 2001 Ford Mustang alternator, 2002-2004 Ford Mustang charging system replacement, or Remy 23723 alternator, this unit aligns with the listed fitment and electrical specifications.

Common Issues This Part Can Address

  • Low battery charge or repeated battery drain
  • Dim headlights or unstable electrical output
  • Charging warning light on the dash
  • Alternator noise or charging failure
  • Voltage irregularities in the vehicle electrical system

Installation Notes and Tips

Verify that the vehicle is equipped for a 105-amp alternator before installation. Confirm pulley alignment, connector style, and mounting points against the original unit on the Ford Mustang. Because this alternator uses an internal regulator and clockwise rotation, matching the original charging-system configuration is important for proper operation.

Quality Assurance

Remy Premium Remanufactured parts are remanufactured replacement components built to meet the listed OE application requirements for the Ford Mustang platform. Part number 23723 is specified for 2001-2004 Ford Mustang fitment only.
