Description
Glow Plug Terminal Nuts, Set of 8, Duramax | 2001-2016 — 10251
This set of 8 replacement glow plug terminal nuts secures the glow plug wiring to the terminal on each glow plug. New ACDelco glow plugs for the LLY, LBZ, LMM and LML Duramax do not come with terminal nuts, so you'll need a set to finish the job. The old nuts are small, easy to drop into the engine valley, and often corroded or seized after years of heat. These M4 x 0.7 serrated flange nuts grip the terminal to keep the connection tight. They fit 2001-2016 Chevy Silverado and GMC Sierra 2500HD and 3500HD trucks with the 6.6L Duramax (LB7, LLY, LBZ, LMM and LML) and 2006-2016 Chevy Express and GMC Savana vans with the 6.6L Duramax (LLY, LMM and LGH).
Do new glow plugs come with nuts? New ACDelco glow plugs for the LLY, LBZ, LMM and LML do not include terminal nuts, so order this set with your glow plugs. New LB7 glow plugs already come with nuts.
