Description

The Merchant Automotive Glow Plug Reamer Tool is designed for all 6.6L Duramax engines from 2001-2025. This tool effectively removes carbon and soot buildup from glow plug holes, which is crucial for preventing glow plug tip breakage during installation. Ceramic glow plugs require the use of this tool for a safe and reliable installation. The tool is hand-operated and can be used with grease on its flutes to capture debris.
