Glow plugs play an important role in the everyday life of a diesel engine. They are used to heat up and help with the starting of a diesel vehicle. Over time they begin to wear causing issues starting. This is often the case in the colder winter months. Glow plugs get it going when the engine is cold or ambient temperatures are low. It takes only two or three seconds for glow plugs, once activated, to generate sufficient heat to warm the engine block so that it's safe to start the vehicle.
