Glow Plug Replacement

These pencil-shaped objects serve as the diesel engine equivalent to the spark plugs found in conventional gasoline engines. Unlike spark plugs, glow plugs use heat to get an engine running. In cold weather, the glow plugs in your diesel engine play an especially important role. When temperatures are low, diesel engines often have trouble igniting their fuel initially and getting started. Glow plugs will wear out over time and with continued use.

Air is required to reach a certain temperature before fuel ignition can occur, but diesel engines can absorb heat into the metal components when temperatures are low, making it difficult to maintain the necessary temperature for fuel to ignite. Glow plugs let off heat quickly, allowing the vehicle to warm up quickly and start with relative ease. While glow plugs gather heat, they let off a small light or glow, which has led to this process often being called “glowing”. After glow plugs finish warming a diesel engine, it should start with no troubles.
