What is Glow Plug?
A glowplug is a heating device used to aid in starting diesel engines. In cold weather, high-speed diesel engines can be difficult to start because the mass of the cylinder block and cylinder head absorb the heat of compression, preventing ignition. Pre-chambered engines use small glowplugs inside the pre-chambers.

What causes glow plug failure?
Usually, glow plug failure is due to excessive heat, or high voltages reaching the plug. High voltage can be caused by a controller that is starting to go bad. Additionally, if there is faulty wiring or a problem with the controller, the glow plug(s) may be receiving power all the time.
What happens if a glow plug breaks?
Disturbing the broken glow plug will break the seal and the cylinder will lose compression hence the engine won’t run unless it’s fixed properly by taking the cylinder head off.
Can a faulty glow plug damage the engine?
Damaged glow plugs or a faulty glow plug control module can cause white smoke on engine start-up. There are also many other possible causes for an excess of white smoke, including low engine cranking speed, low compression, and air in the fuel system.
How long should glow plugs last?
Glow plugs should last for as long as 100,000 miles; they will gradually deteriorate due to wear and tear over this period. The good news is that not only are glow plugs incredibly long-lasting, but they’re also among the most cost-effective car parts to replace.
