Help from 4.2TD owners required

[vanjun]

Today I repaired my radiator, reinstalled it and filled it with water. I ran the engine for a while with the bonnet open to get the engine hot enough to check the water level.

While I was waiting I noticed a fine wisp of smoke and found that it was coming from the wires connected to a sender or switch on the inlet manifold. The rubber on these wires had deteriorated and they were red hot. I turned the ignition off and went to check my Gregory's manual. I could not find any reference to this sender anywhere in the manual. Can anybody tell me what it is?


Mine is a 2000 GU td4.2t.

It a heating element, like a glow plug. It preheats the air in the inlet manifold

Hi Paul,

Mate i have 2 TD42s in my driveway. A 1992 GQ TD42 and a 2005 GUIV TD42Ti intercooled and on both engines that is a cast blank in the inlet manifold and is not in use.

Sorry mate. If you can see sparks then you have a short and i would be isolating the two wires.

pm Yendor on here mate, he is a Auto Elec and should be able to guide you straight. he is very helpful and will figure it out for you.

Good luck mate

sorry boss.....hehehehehehe

Thanks guys. The heating element would make sense. The wires are insulated with rubber rather than plastic which generally indicates that they are meant to be more resistant to heat. The wires were very hot, I didn't see any sparks but there was a small amount of smoke coming off them. The rubber insulation has perished and exposed the bare wire. I would assume that this element would only be powered for a short time?? Is it factory?? Can I disconnect it without any problems although it is very cold during the night at the moment.

Thanks

I have seen a few disconnected without any issues.

[Yendor]

Yes they get very hot very quickly and only work for short period of time.

I think they are for colder climates then we have here in Australia.

If you main glow plugs are working correctly you shouldn't have any starting problems.

You can disconnect it and see how it does start, you can always replace it later.

They might not be that expensive to replace anyway.

[vanjun]

I'll disconnect and see how it goes for now. Thanks for the info, I'll let you know how it goes.
