Remanufactured Alternator for Buick Allure and LaCrosse

MPA Electrical Part Number 11125 is a remanufactured 12-volt alternator built for charging-system replacement on select 2005 Buick applications. It is configured with a 120-amp output, internal regulator, internal fan, and a 6-groove serpentine clutch pulley for clockwise rotation.

Key Features

  • Remanufactured alternator from MPA Electrical
  • 120 amps output for 12-volt charging systems
  • Internal regulator and internal fan
  • 6-groove serpentine clutch pulley
  • Clockwise rotation
  • Manufacturer listed as Bosch
  • Part number 11125

Product Details

This remanufactured alternator is specified for 2005 Buick Allure and 2005 Buick LaCrosse applications. The unit is built around a Bosch design and uses an internal voltage regulator to manage charging output, while the internal fan supports alternator cooling during operation. The 120-amp rating makes this a direct replacement option for vehicles that require this exact electrical and pulley configuration. Part number 11125 is also referenced under Quality-Built 11125 for the same application.

Common Uses

  • Restores charging output when the battery is not staying charged
  • Addresses dim lights or electrical performance issues caused by low alternator output
  • Replaces a noisy, worn, or failing alternator assembly
  • Supports proper system voltage in 2005 Buick Allure and 2005 Buick LaCrosse models

Installation Notes

Verify pulley style, amperage, rotation, and connector match before installation. Confirm the vehicle uses a 12-volt system with a 6-groove serpentine clutch pulley and clockwise rotation. For best results, inspect the battery, belt condition, and charging cables during replacement so the new alternator can operate within the correct system parameters.

Quality Assurance

MPA Electrical remanufactured components are rebuilt to meet application-specific charging requirements. This alternator is listed with Bosch as the manufacturer and cross-references Quality-Built 11125 for the same fitment.
