CUCV GlowPlugs

[sporanox]

I have had 4 GlowPlug wires catch on fire this summer. I do not know if it is short in the glowplug or an issue with the wire and possibly as mouse. What should I use to replace the glowplugs and wires? I am not sure if I want to patch the wire or install a new run. Is it part of the wiring harness? If so, how much would a new harness cost and where could I get one?

Many Thanks

It is my understanding that the portion of the GP harness that connect to the individual GPs is made from fusible link wire. If it is burning up, there may be one or more GPs that are shorted to ground. Take a look at the TMs for the GP system diag procedure. A simple multimeter will tell you all you need to know about the health of the GP system.

The green portion of the GP wires are indeed fusible link wire. Over the years oil and dirt can do a number on it.

You could fix yours or like PP said buy another one.

As far as replacing the glowplugs, which ones are recommended? Also I saw tools such as a glow plug extractor tool for $100, is it nessecary?

It has been discussed many times. The latest plugs that work great are the AC60s. They do require that the GP wire terminal ends be replaced with 1/4" female ends or to grind the new plug terminals to fit the smaller stock ends.

If the plugs are swollen then the tool might be required.
