Description
Duramax Glow Plug Reamer Tool for All Model Years Including the L5P | 2001 - 2026
The Merchant Automotive Duramax Glow Plug Reamer cleans carbon and soot out of the glow plug bores before you install new glow plugs. It fits all 6.6L Duramax engines, LB7, LLY, LBZ, LMM, LML, LGH and L5P, in 2001-2026 Chevy Silverado and GMC Sierra 2500HD and 3500HD trucks and 2006-2016 Chevy Express and GMC Savana vans.
GM's service information explains that soot builds up between the glow plug and the bore during normal operation. If it isn't removed, it can side load a new glow plug and cause premature failure. On the L5P, the glow plugs have ceramic tips, and GM calls for reaming the bore every time a glow plug is removed (GM bulletin 23-NA-032). If a glow plug tip breaks off, it can fall into the combustion chamber, and GM directs technicians to inspect the cylinder for the tip or other debris.
