Can someone let me know if I'm correct in saying: The original and steel 7V Glow plugs use module P/N 56044671AA. The 5v steel Glow plug Module is P/N 56044671AC? I don't believe the modules are interchangeable between 7 and 5 volt plugs? Is this correct? I wanted to replace my module, but the original AA is not available. Thanks KJJET |

See: viewtopic.php?f=5&t=63799 I am still not sure if they are the same part though. |

Here is the glow plug info I have compiled after doing my own digging a while ago: Factory was 7v ceramic. Later Chrysler released an updated 5v steel plug (and kit) which required an ECM reflash and included a new glow plug module. Then Etecno released a 7v steel plug as a direct replacement for the OEM 7v ceramics, not needing a new glow plug module or reflash. Now it seems within the last 6 months Etecno has released a new design of GX3123. It’s advertised as a 7v steel plug (same as it was before) but is designed to be a suitable replacement for both the factory 7v steel and the factory 5v steel without any changes to existing glow plug modules or ECM flashes. Source: viewtopic.php?p=817721#p817721 Some other helpful info: To determine what glow plugs you have, it’s not enough to check the part number on your glow plug module. Visually inspect the glow plug behind the alternator bracket with a flashlight. If plug has a white ring = 7v If plug has s a red ring = 5v Glow plug modules: 56044671AA: factory glow plug module for 7v ceramic 56044671AC: updated glow plug module - included as part of 5v conversion, and according to this post it also works for 7v ceramics.

We know all the history. Bin there, done that. Just trying to get a grip on GP Module. AA VS AC that's it. Thanks KJJET |

Per this, part number AA AC is the same. Supposed to be used with ceramic glow plugs. http://www.factorychryslerparts.com/pro ... 671AC.html |

They seem to be the same Bosch relays with an updated Chrysler p/n for some reason. Unsure if they were made "more durable..." I doubt it. The glow plug relays do fail, but I think from age and repeated loads. Bosch usually makes a good product.

Thanks for the awesome list of GP info Weeks! I only have one last question for this list. Do the new 7v plugs help significantly in cold temps? I've only seen my 5s down to freezing, and I had no problems.

It seems the "best to worst" is: 1 - 7V Ceramic 2 - 5V Steel 3 - 7V Steel |

Ok, thanks again, but that's weird that an element with almost 30% more V doesn't get hotter or work better. I wonder why? I also wonder what GPs most people in the north are using. |

Thing is that I if you can plug the jeep block heater when is below 10 degrees, it doesn't matter what glow plugs you use. Ceramics seem to be the king in extreme cold weather. But 5-8 hours in extreme cold shouldn't prevent the engine from starting even with steel plugs, as long as the diesel doesn't gel. |

ok, thanks for saving me $100+ to change out to the 7's fellas! I'll just run them until they give me problems I guess. Going to suck if I get back to the truck after 3 days packed-in with a pack full of elk meat and it won't start though. I guess I'll bring a gen for the block heater, and wire up another battery. |
