GM Genuine Parts 12608820 Starter Heat Shield — for Select GM Models

Heat-related starter failure, difficult hot starts, or a starter motor that cranks slowly when the engine is warm — these are common signs that your starter heat shield is missing or damaged. The starter heat shield is a thermal protection component that deflects engine and exhaust heat away from the starter motor assembly, preventing damage and premature failure . A missing or deteriorated shield allows heat soak to damage the starter solenoid and windings, leading to expensive repairs. Replacing it with this genuine GM part restores proper thermal protection and extends starter life.

This is a factory-original GM starter heat shield (OE part number 12608820). It is a direct replacement component designed, engineered, and tested to rigorous standards and backed by General Motors .
