Why Do Glow Plugs Fail?
Though most glow plugs have long lifetimes, some do fail before the 100,000-mile point. Here are some of the main reasons that glow plugs fail early:
- You have the wrong glow plugs for your engine
- Your engine excessively overheats
- Your engine operates at voltages that are too high
- Your power supply is too long (often due to a stuck relay)
- Your pistons are damaged
- Your valves are broken
- You have a seized piston ring
- The injectors have dripped onto the glow plugs and eroded them.
Another common cause of damaged glow plugs is high-amperage battery chargers, which are used to improve engine starting.
These chargers can provide a voltage high enough to explode the glow plug tips.
If you invest in a battery charger, choose an intelligent one to avoid this problem. DIY Car Service Parts stocks a comprehensive range of batteries and chargers for all makes and models.
Tip: if your glow plugs failed at the same time, they didn’t fail naturally because of wear and tear.
