Valeo supplies starters to major vehicle manufacturers, and this unit is built as a new replacement starter rather than a remanufactured unit, helping reduce the risk associated with worn core components.

Installation Notes and Tips

Verify the vehicle’s original starter specifications before installation, including 12-volt system voltage, clockwise rotation, and 10-tooth drive count. Confirm fitment by model year and chassis details where noted, especially for 2008 Mercedes-Benz C300 vehicles with South Africa-built or Germany-built chassis breakpoints. Inspect battery condition, cables, and charging system output during replacement to avoid repeat starting issues.
