You were using the VW special tool 'double-jointed elves' to work on your van, weren't you?

You want to try doing the glowplugs on the T25 TD motor - I remember spending a lot longer than 1.5 hours changing them on mine a few years ago.

How easy are they to do on a 1.9TD? I think mine need replacing as it's hard to start when it's very cold.

I did mine as soon as the cold weather started. took nearly 2 hours. Make sure u have a 1/4" drive socket set to make life a lot easier. Upon replacing them I found only 1 out the four to be working. Just to show how did it ever really start. Now just a touch with the key and shes running even on the coldest mornings. No more hammering the battery or starter motor. well worth the work!

Ummmmmmmmm can i ask a daft question as a non technical person who is keen to learn......

i've seen glow plugs mentioned quite a few times recently. I'm just wondering what they are and what they do ?

Are they the deisel version of spark plugs ??

cheers

On a diesel engine, the diesel needs to be hot to enable an explosoin to take place in the combustion chamber. When running, the hot engine heats the diesel before it reaches the conbustion chamber to create the explosion.
But when the engine is cold ie before you start it, you need a way to heat the diesel to allow an explosion to take place to get the engine running.
This is the job of the glow plugs. They superheat the cold diesel.

This is my understanding of it anyway. Someone will be able to explain it in a better way im sure!

To avoid any misunderstanding the glowplug only heats the air in the combustion chamber & not the diesel fuel, may have been what you meant wehey.

That makes sense to me :).

Don't know where the combustion chamber is -but thats why i have a garage round the corner

My van doesn't start very easily in the cold and today I've been unable to start it, even though it's not that cold :confused:

How do you get the plugs out of a 1.9TD? I can't see how you can get them out without removing the injection lines and the injection pump?.

It's looks a very hard and fiddly job to change just four plugs :eek:

Hi Chris, yes it is very fiddly but is worth doing and you wont do it with normal spanners there is a link on here somewhere that shows photos and the tools you need, just done mine and couldnt get out the No2 so left it, but it starts on the button now

I see that Laser tools (www.lasertools.co.uk) have brought out a range of specialist tools for Diesel injector removal and Glow plug removal, special sockets and double offset ratchet spanners. If memory serves Laser are always quite cheap on the pocket when it comes to paying at the till.

I am a petrol head, but saw ths little lot and thought of your Derv burning chaps in the season of Good Will to all Men and Ladies. So I hope you all have a great 2008. A Happy New Year to You All.

I`ve just had the glow plugs replaced on my 1.9tdi by a diesel specialist (Diplock Fuel Injecion Services) who reccomended using quality glow plugs as they warm up quicker and last longer.They also said that its better to wait a few seconds after the glow plug light goes out before starting the engine to make sure the plugs are properley warmed up.

t4_chris
30-12-07, 23:01
Thanks, C14YCD A: mine is a longnose westy, so I'm not sure if you can remove the front panel and tip the rad? but it has more room in the front anyhow!

biggelmo, I always wait a few seconds as you say, I believe you have approx 15secs after the light goes out to start the engine.
How much did your specialist charge to change the plugs?

I see you are a Kona fan T:

Thats right t4 chris I love old Konas and are currently looking for a 95ish decent quality steel frame to build up as a project.
I`m not sure what the cost of the glow plugs was as they were part of a major service (cam belt & tensioners,other belts,oils,filters and rear pads) that cost 560 (made me wince a bit).

Hello again Forum. Haven't been around for a while (not that I was a massive poster on the previous incarnation of the forum, but hey...

That's great - I'll be taking a look at that link when my account gets upgraded (just coughed up a tenner, so any minute now...)

Same as many others here, my 1.9TD decided not to start one morning. I called out Mr Recovery Man and he reckoned the glow-plug relaye had gone, but fitting a new one made no difference. So I took matters into my own hands and traced the current from the relay all the way down to where the wire goes just out of easy sight and gives current to the glow plugs, and it was getting there fine.

Until I get this fixed, I'm starting the van in the mornings with two pencils and a length of wire... not that I'm recommending this method of course I: but if anyone's interested - I've taken a length of wire that's long enough to reach from glow plug no.3 (presuming that no.1 is nearest the battery) to the positive terminal on the battery (I've gone for glow plug no.3 cos that's the one I can see). I've taped a pencil on each end so that the end of the pencil is about level with end of the piece of wire (my wire happened to have a spade connector on each end). I then reach the pencil down to glow plug no.3 and touch the spade connector onto the end of it, and then touch the other end of the wire (plus pencil) onto the positive terminal on the battery. This heats things up, I turn the key, broom! (with plenty of smoke, mind you)

So if, say, glow plugs 1 and/or 2 are knackered, would this stop current getting across to 3 and 4? Or am I maybe looking at corrosion where the power lead reaches glow-plug no.1 maybe? Can't quite twist my neck round enough to see in there...

i'm wet , tired and need my van for tomorrow and i cant get a decent look at my plugs .
my hands are to big and as far as i can see there's no way i'm getting it to the garage on monday cos the battery is now flat .......
someone come round and give me moral support or fix it for me ....

Blow torch in the air intake will get you to a garage, or will get it started anyway. Worked for me for a few days a couple of winters back before I changed the plugs (or worked out how to)! 1.9TD
