Product Details

Remy Premium Remanufactured part number 20446 is an alternator for vehicles originally equipped with Delco/Delphi-style charging components. This unit is specified as a clockwise-rotation, externally fan-cooled alternator with an internal regulator, making it a direct-fit service part for restoring charging performance on the listed applications. The Remy 20446 is also cross-referenced to 1101321 and 1101565 for the same application.

Common Uses

• Restores charging output when the battery is not staying charged
• Addresses dim lights or electrical instability caused by alternator wear
• Replaces a failed internal regulator in the charging system
• Corrects belt-driven charging issues when the original alternator is noisy or weak
• Supports proper system voltage on 12-volt vehicles

Installation Notes

Verify pulley alignment, rotation direction, amperage rating, and connector match before installation. Confirm the vehicle’s original alternator configuration against the listed fitment, especially for 1989 Pontiac Sunbird applications with wo/AC or Std notes. Because this is a remanufactured electrical component, inspect the charging circuit, battery condition, and belt drive system during replacement to help prevent repeat failure.

Quality Assurance
