Bosch AL8854X Alternator

Remanufactured Bosch Alternator

Bosch AL8854X is a remanufactured 12-volt alternator built for charging-system replacement where stable output matters. It uses an internal regulator, internal fan, and a clockwise rotation design with a pulley included for a direct-fit service solution.

Key Features

• 140-amp output for charging-system service
• Remanufactured Bosch alternator with aluminum case construction
• Internal regulator and internal fan design
• 6-groove pulley with 56.5 mm outside diameter
• Clockwise rotation and 6S-CP pulley/belt type

Detailed Description

This Bosch alternator is engineered as a remanufactured replacement for vehicles that require a 12-volt charging unit with a 140-amp rating. The aluminum case and internal cooling layout support consistent operation, while the included pulley and internal regulator simplify matching the original charging-system configuration. Bosch AL8854X is a practical choice for Cadillac CTS charging-system repair when the original alternator is no longer maintaining proper electrical output. Bosch AL8854X also cross-references 20821397 for the same application.

What It Helps Solve

• Low battery charging caused by a worn alternator
• Battery warning lights related to charging-system faults
• Electrical instability from inconsistent alternator output
• Charging loss from pulley or regulator wear

Installation Notes and Tips

Verify pulley groove count, rotation direction, amperage rating, and connector orientation before installation. This alternator is not one-wire capable. Confirm fitment for 2010-2014 Cadillac CTS applications, including 2010-2013 models listed for 140-amp alternator service.
