Product Details

Remy 12253 is a remanufactured alternator for the Jaguar S-Type, engineered for 2000-2004 model years with confirmed coverage for 2000-2003 Jaguar S-Type and 2004 Jaguar S-Type to chassis M45254.

• Noise or wear associated with a failing alternator assembly

Installation Notes and Tips

Verify the vehicle’s original alternator configuration before installation, including 12-volt system requirements, clockwise rotation, and pulley style. Confirm fitment by model year and chassis break for 2004 Jaguar S-Type applications. Inspect the battery, drive belt, and charging circuit before installing the replacement alternator to help avoid repeat charging-system faults.
