| Post subject: | Block Heater Replacement |
I want to order ALL of the related parts to replace our block heater so I have them on hand, if needed. The 2005 parts CD I have lists several numbers: HEATER, Engine: 4557 686AB 1 ED0 55037 539AA 1 EN0 56041 304AB 1 EK0 CORD, Engine Block Heater: 5159 972AA 1 EN0 56041 974AA 1 EK0 56044 160AA 1 ED0 6015 756 1 ED0 STRAP: Tie 6503 096 Can someone confirm if these are correct and if all of them are needed? Thanks! DOC |

if this part is like some of the others for our rigs there are multiples depending on the vin.. i'd call the parts dept of the local stelership and use their computers and your vin to find the exact one and order it.. takes the guess work out of it |

Doc the block heater should be a pretty "dumb" part that should just work unless 1) the power cord is shot or 2) the heater element has burned out. Seems to me simple continuity checks on the cord and the element should suffice to locate any problem. The cord is just like any normal 110v electric cord and I strongly suspect the heater element is functionally identical to a hot water heater element. If the latter is true in the past I was easily able to id bad hot water heater elements but checking for continuity. As to your PNs your best bet is to check with a local dealer as the online parts manuals are not very helpful. As best I can tell: 4557686AB 1 ED0 - cannot find that # in the 06 KJ parts manual copy I have but the ED0 engine code does not match the ENR engine code that's supposed to be for the 2.8L CRD 55037539AA is not the block heater it's the viscous heater 56041304AB is a block heater for a gas engine. I do not know if it will fit the CRD Check down where the cord attaches to the heater, see 1st pic at viewtopic.php?f=98&t=74594 . It's been several years since my son and I replaced his block heater cord so I don't really recall how it attached down there (plug vs regular screw fittings) but it may be that a regular hardware store 3 wire cord can be used. In any case the local dealer had it in stock, don't have PN, for like $25. It's a flat 3 wire with insulated wires contained in an external rubber like sheath and that sheath is prone to cracking if it's left wadded up attached to the dip stick as it came from the factory. If the sheath is not cracking and the wire has appropriate continuity replacement is not truly needed. Strap - I have no clue what this is. The only strap my son and I saw was a simple reusable zip tie holding the bundle heater cord to the dip stick. I do vaguely recall some sort of metal clip, possibly a wire stand off clip, down near where the wire hooks in that gave me a bit of a fit but it was not anything that should need replacing. |

Doc, The 2006 parts list shows: 56044738AA for block heater, MPA has them for about $47 56044765AA for cord, about $16.50 Not sure if these are correct or the part numbers you have from 2005. I have 10 of the block heaters (400 W), but no cords. $25 shipped each Hard to imagine these things going bad. |

My cord is shot, been putting off getting it because I live in Nashville. With this past week being in the 20's, I wish I hadn't put it off. Almost wish I needed a block heater at that price. |

Just want to have all the right parts on hand in the event they are needed. It looks like we are going through an unusually cold winter in the northeast. Do not want to be without a fully functioning block heater for long. DOC |
