What are the symptoms of a bad glow plug?

The most common symptoms of a bad glow plug are engine misfiring, hard starting, black or white exhaust smoke, decreased fuel efficiency and rough idling.


Disassembly and installation:

When a glow plug needs to be replaced, it is recommended to apply a synthetic engine oil around each glow plug and ideally let it penetrate for at least a week. This reduces the risk of shearing and makes removal easier. When removing, each glow plug should be manually disconnected from its electrical wire. When this is complete, each plug can be individually uninstalled with a suitable torque wrench.

Once an old glow plug is removed, a glow plug hole reamer loaded with silicone-free grease should be used to clean and empty each hole of carbon deposits. After that, the new glow plugs can be manually installed into their seats and then tightened with a correctly set torque wrench.
