Glow plugs help to provide the additional heat in the combustion chamber. If the required temperature is not reached due to faulty glow plugs, the engine’s performance will be weakened, and it will have to work extra hard to meet the demands of the road. The vehicle’s fuel efficiency will be negatively affected.

When temperatures drop, your engine may need additional help to warm up in order to start and run at the necessary operating temperature.
Should you warm up a diesel engine before driving?
