Glow Plugs

If your diesel engine has started struggling when you start it, that could mean there’s a problem with one or more of your glow plugs. If only one or two glow plugs have failed, you will probably still be able to start the engine, but it will likely struggle a bit more.

Glow plugs typically last a very long time, around 160,000 kilometres. There are some factors which could cause your glow plugs to fail more quickly such as your engine overheating, using the wrong type of glow plugs, or the engine operating at a voltage that’s too high.

The right type of glow plugs for your vehicle will depend on the type of engine. You can check your owner’s manual for more information or ask your local Natrad technician for advice.

No. Glow plugs are included (or excluded) based on the OEM’s needs. Older diesel truck engines may not include glow plugs, which act as a form of preheating. However, modern vehicles feature an electric start with inbuilt glow plugs.

Most glow plugs will last around 1,609 kilometres in a diesel engine. However, they can either fail before then due to damage or defects, or last longer. But, without glow plugs, your engine will not start properly, so it’s best to ensure yours are up to scratch.
