  2. Locate Glow Plugs: Identify the location of the glow plugs on your engine. They are typically found on the cylinder head.
  3. Remove Electrical Connectors: Carefully disconnect the electrical connectors from each glow plug.
  4. Remove Old Glow Plugs: Using a suitable glow plug wrench, carefully loosen and remove the old glow plugs. Be cautious not to break them, especially if they are seized.

5. Operation

The NGK Glow Plug 97618 operates automatically as part of your vehicle's pre-heating system. When the ignition is turned on in a diesel vehicle, especially in cold conditions, the glow plugs heat up rapidly to raise the temperature in the combustion chamber. This pre-heating assists in the ignition of the diesel fuel, allowing for a quick and smooth engine start. The vehicle's engine control unit (ECU) manages the glow plug activation time based on engine temperature and other factors.

6. Maintenance

Glow plugs are wear items and do not typically require routine maintenance. However, regular vehicle servicing and inspection of the glow plug system are recommended. If you experience difficulty starting your diesel engine, especially in cold weather, or if a "check engine" light illuminates, have your glow plugs and associated electrical system checked by a qualified technician.

Avoid using harsh chemicals or abrasive materials on the glow plugs, as this can damage their protective coating.

7. Troubleshooting

If you encounter issues, consider the following common problems and potential solutions:

ProblemPossible CauseSolution
Difficulty starting engine (especially cold)One or more glow plugs are faulty or worn out.Test glow plugs for resistance/continuity. Replace faulty glow plugs.
