4. Installation (Setup)

Installation of glow plugs requires mechanical knowledge and specific tools. If you are not experienced with automotive repairs, it is recommended to have this procedure performed by a qualified technician.

1. Safety First: Ensure the engine is cool and the vehicle's battery is disconnected to prevent accidental starting or electrical shock.
2. Locate Glow Plugs: Identify the glow plugs, typically located on the cylinder head.
3. Disconnect Wiring: Carefully disconnect the electrical connectors from each glow plug.
4. Remove Old Glow Plugs: Using an appropriate glow plug wrench, carefully loosen and remove the old glow plugs. Exercise caution to avoid breaking them in the cylinder head.
5. Inspect and Clean: Inspect the glow plug bores for carbon buildup or debris. Clean if necessary.
6. Install New Glow Plugs: Thread the new NISSAN Genuine Parts 11070-AD200 glow plugs into the cylinder head by hand to prevent cross-threading.
7. Torque to Specification: Using a torque wrench, tighten the glow plugs to the manufacturer's specified torque. Overtightening can damage the glow plug or cylinder head.
8. Reconnect Wiring: Reattach the electrical connectors to the new glow plugs.
9. Reconnect Battery: Reconnect the vehicle's battery.
10. Test System: Start the engine and check for proper operation and any warning lights.

5. Operation

Glow plugs operate automatically as part of the engine's cold start system. When the ignition is turned on, especially in cold weather, the engine control unit (ECU) activates the glow plugs. They rapidly heat up to high temperatures, preheating the air in the combustion chamber. This preheating reduces the ignition delay of the diesel fuel, allowing for smoother and quicker engine starting. Once the engine starts, the glow plugs typically remain active for a short period (afterglow) to reduce emissions and improve engine smoothness during warm-up.

6. Maintenance

Glow plugs are wear items and do not typically require routine maintenance beyond proper installation. However, regular engine servicing and inspection of the glow plug system can help ensure their longevity and proper function.

• Regular Inspections: During routine vehicle maintenance, have the glow plug system inspected for any signs of damage, corrosion, or loose connections.
• Avoid Contamination: Ensure that no foreign materials or liquids come into contact with the glow plugs or their electrical connections.
• Replace as a Set: If one glow plug fails, it is often recommended to replace all glow plugs as a set to maintain consistent engine performance and prevent future issues.

7. Troubleshooting

If you experience issues related to engine starting, particularly in cold weather, your glow plugs may be a contributing factor. Common symptoms and potential solutions include:

• Difficulty Starting in Cold Weather:
  • Possible Cause: One or more glow plugs are faulty or have failed.
  • Solution: Test the resistance of each glow plug using a multimeter. Replace any glow plugs that show infinite resistance or significantly different readings from the others.
• Excessive White Smoke on Startup:
  • Possible Cause: Incomplete combustion due to insufficient preheating, often caused by faulty glow plugs.
  • Solution: Inspect and test glow plugs. Replace as necessary.
• Engine Misfires or Rough Idling After Startup:
  • Possible Cause: Glow plugs not functioning correctly during the afterglow phase.
  • Solution: Have the glow plug system and associated wiring checked by a professional.
• Glow Plug Warning Light On:
  • Possible Cause: Indicates a fault in the glow plug system.
  • Solution: Use an OBD-II scanner to retrieve diagnostic trouble codes (DTCs) and pinpoint the exact issue.

For complex issues or if you are unsure about troubleshooting steps, consult a certified NISSAN service center.
