Product Details

This part cross-references 10463393 and 10480097 for the same application. The Remy 20339 is a practical choice when replacing a worn charging unit on a 1993 Buick Roadmaster or 1993 Chevrolet Caprice with the correct output and rotation requirements.

What This Alternator Helps Address

  • Battery warning light caused by charging-system underperformance
  • Low system voltage at idle or under electrical load
  • Dim lights, slow accessory operation, or weak battery recovery
  • Noise or wear associated with an aging alternator assembly
  • Replacement needs for a 1993 Buick Roadmaster or 1993 Chevrolet Caprice charging system

Installation Notes and Fitment

Compatible With 1993 Buick Roadmaster, N/A; 1993 Chevrolet Caprice, N/A; and 1993 Chevrolet Commercial Chassis, N/A. For Chevrolet Caprice and Commercial Chassis applications, the notes specify Police or Std configurations with 105 amps. The Buick Roadmaster listing notes that it is not compatible with vehicles with less than 105 amps capacity. Verify amperage, rotation direction, pulley configuration, and regulator style against the original unit before installation. Part number 20339 should be matched to the vehicle’s charging-system requirements before removal of the existing alternator.
