Implementing proper driving habits and regular maintenance can help prolong the lifespan of your glow plugs:
- Allow the engine to warm up before driving aggressively
- Avoid frequent short trips that don’t allow the engine to reach optimal temperature
- Use quality fuel and additives recommended for diesel engines
- Regularly inspect and replace glow plugs as part of scheduled maintenance
Proper Starting Procedures
Following correct starting procedures reduces stress on glow plugs:
