Starter Overview

Bosch SR8646N is a new 12-volt starter built with a permanent magnet gear reduction design for reliable engine cranking. It is a direct replacement starter for a wide range of GM and related applications, including Chevrolet Impala, Chevrolet Camaro, and Cadillac CTS fitments.

Key Features

  • Permanent magnet gear reduction design for efficient starting performance
  • 12-volt new starter with integrated solenoid attached

  • Clockwise rotation with 12-tooth drive and flange mounting
  • Designed for automatic start/stop operation

Detailed Description

The Bosch Starter (New) SR8646N is engineered as a replacement starter for vehicles that require a clockwise-rotation, flange-mounted unit with a grounded case. Its PMGR construction uses a compact gear reduction layout to deliver starting torque in a smaller package, while the aluminum housing and closed nose help support durability in demanding electrical starting systems. This Bosch SR8646N starter is listed for applications such as 2008-2014 Cadillac CTS, 2010-2014 Chevrolet Camaro, and 2008-2011 Chevrolet Malibu.

Bosch designs, builds, and tests this starter to meet performance and reliability expectations for modern starting systems. This part cross-references GM 12610857 for the same application.

What It Is Used For

  • Restoring engine cranking when the original starter no longer engages properly
  • Addressing slow or inconsistent starting caused by starter wear
  • Replacing a unit with damaged housing, nose cone, or internal drive components
  • Correcting starting issues related to solenoid or electrical starter failure
  • Supporting vehicles equipped with automatic start/stop operation

Installation Notes and Tips

Verify voltage, rotation, mounting type, tooth count, and case dimensions before installation. This starter uses a flange mount and does not include mounting hardware or shims. Confirm the vehicle's original starter configuration matches the listed fitment before replacement.

Quality Assurance

Bosch Premium Starters are designed, built, and tested for performance and reliability. The SR8646N is a new unit, not remanufactured, and is built to Bosch's starter product standards.
