DURAMAX GLOW PLUG

I have a code for number 4 glow plug. How long can you drive with glow plug code? I do not live in cold weather area. Not sure I understand what glow plug does exactly. Thanks

  • Little Cummins engines have grid. Big Cummins have glo plugs. I did not realize our glo plugs were not working. I just had them replaced. When any thing doesn't work I get it repaired.

    UH where are the "glow plugs" located on my Cummins?


    You know darn well that the Cummins does not have glow plugs.
  • That glow plug is on the Drivers drives side. They are super easy to change. Just like a spark plug. Between mine and my brothers, I've changed 5 myself. Since you don't live in a cold climate I'm pretty sure it will not hurt a thing but do you want to keep looking at the check engine light? It's a 5 minute job to replace one. Will take longer removing the and replacing the wheel liner than changing out the plug. They just help on colder days to start the motor. Probably wouldn't notice a difference on warm days but when it gets cold I can really tell if I have one not working.
