| Post subject: | Fan Swtich or Temp Sensor? |
Ok, I need some help. Through a process of replacing fried wiring, I came across a purple (violet per wiring diagram). On the diagram (from the repair manual) it says its a temp sensor. It has a sparkplug-like connector that connects right above the fan area. First question, is there a replacement wire with connect and is this a coolant fan switch that it connects to? If so is there any trick to replacing it? And is this the type I'd need, Napa ECHTS6178?  Thanks -Dan |

There is no fan switch on a vehicle with an engine/belt driven fan.  This what you're showing us is the engine coolant temperature sender, which is what drives the temperature gauge on the dash. Which (specific) repair manual are you using? Yes, there is a replacement wire with connector, but the p/n's in my office, so that'll have to wait. |

That's why I'm a beginner  I'm using the '68 plymouth service manual. I bought it from rockauto, its not a haynes. The reason I ask this is because I have to replace this wire because its partially melted. So while doing this I might as well replace the sender then right? I'm just trying to start off with a clean slate.

Nothin' wrong with your question, just having a little fun. Good job getting the real manual. Did you get the other two books in this thread yet? Replacing the sender is a good idea. |

Not yet, I searched for them back when you first told me to get them but since then I got sidetracked and haven't looked since then. |

The temp sender replacement pigtail is NAPA Belden number 784827:  When you buy the replacement sender, get the Echlin unit, not the cheaper generic -- the quality difference is worth the couple extra bucks. |

Thanks Dan, I appreciate it. Hopefully today I can go pick that up along with some more wire to finish up this rewiring job. Check this out, I have been going through the service manual diagram and have been replacing wires where they are supposed to be (I can't rely on where they were. Well, I followed at wire from the alternator and it goes in through the firewall (where it connects in there I haven't got that far). But on the diagram it goes to the regulator I believe ( I dont have the diagram in front of me). Maybe this is why wires got fried huh? Thanks again for the p/n Dan |

Hey Dan, I got the connector and temp sending unit just a bit ago. They had a hard time finding those parts and wanted to sell me the generic sender but I said no, that I'd wait for the echlin part. Its coming along, slowly but surely. Thanks again |
