Jumpy/Dispatch 1998 XUD9 TE Glow Plug Change

Oscarklemo · 2025-06-11 15:54:37

Hi

I will now embark on the next step of fixing my Jumpy.

I'm about to change glow plugs and fuel filter.

I've detected the glow plugs, but it need some support in changing them.

I have found no videos on how to change in this model. Other motors seem to be simpler, just taking off the intercooler.

In my case, it looks like I need to remove the starter, coolant container and whatnot to change the glow plugs?

RegW · 2025-06-11 16:33:20

Cant help I'm afraid never done this job on that engine.

"Starter"? are you sure?
That's down below, maybe you mean injector pump?
because I can see how that could get in the way as well as that fuel filter housing
On mine the coolant reservoir is just held on by one bolt that can be loosened to
allow it to slide off and moved out of your way.

Hopefully someone else here has done this job and has some tips and tricks

Updated it with colors

I thought the turquoise thing was the starter, but you're right of course

The yellow one is my fuel filter. But the red one looks like a fuel filter as well, but what is it?

RegW · 2025-06-11 19:36:29

Not sure, but will guess the silver can filter is perhaps where someone decided to use an inline can type filter
instead of the black plastic one cos it leaked, or the inline one was easier to swap/service maybe?

I have a rough idea where the glow plugs are and they do look a bit tricky to get at.
Sometimes they can be hard to remove so the more room to work the better.

I just remembered Ken's post about his fuel filter and your thing circled in red is definitely
the original fuel filter so my guess may or may not be relevant

Yes. I checked the owners guide I found on the download page and it says that the filter is the red circled one as well.

In the owners guide they have the oil filler up where the inline filter is...

But as I have no water drainage from the inline filter, wouldn't that explain my white smoke?

I'll try to use the original filter.

But then I'll need to change the tubing...

I'm wondering why you need to change the glow plugs.
Have you done any tests to confirm they are bad or failing?
If not I'd suggest you check
A they are getting a supply from the relay.
B see if one or more fails the resistance test.

All you need is a digital multimeter and
some small spanners to remove the terminals to isolate them
for testing.

A good plug will have a resistance of around 1 ohm
anything over say 6 ohms is probably bad or at least failing.

White smoke that clears when the engine warms up could be bad glow plugs of course
but it could be other things.

I've changed the glow plugs on this engine a few times. You don't need to remove the starter and/or fuel pump. In fact, don't undo the fuel pump unless you're prepared to re-time the engine back up, since the fuel pump is on the timing belt

It's fiddly, but you can do it in place. Expect to lose a couple of the nuts that hold the harness on, keep the old ones for when you do

The right hand two are easy, the second from the left is fiddly, the leftmost one is an arse to get to. Like I say though, with enough patience and the right tools - long socket and extension bars - you can do it.

Even doing the easier 3 is worth it. i think I gave up doing the left one once, and it still made a difference.

Like already said, the red one is the fuel filter housing. 4 allen bolts and the lid comes off.

Another culprit for the glow plugs could be the glow plug relay. Do you have reason to believe they're not working or is this a preemptive maintenance thing?

I have no idea what the yellow circled item is. I don't have it and it doesn't look original. What's on each end of it?

kenbw2 · 2025-06-12 01:09:04

Oh now I look again you're missing the pipe coming out of the top of the original filter housing, which would explain your nonstandard one. Sometimes the filter housing leaks and you have to replace it, which might be why they used the nonstandard one to make it easier

If you're worried about water, it'll drain out of the bottom since oil floats on water. Undo the bottom pipe and it should come out if there is any

Oscarklemo · 2025-06-12 07:03:30

I'm 100% sure the yellow circled one is a fuel filter.

The interesting this is how they fitted it. It sits right in front of the primer pump. Probably just cut the cable there.

But I ordered a new fuel filter a while back which I couldn't fit of course, because I didn't know how to open the can and I saw it was from a cheap Swedish aftermarket car parts chain.

I checked online yesterday and found that the bottom fuel filter seal usually leaks so I ordered a new one for about 5 euro. I'll try and refit the original fuel filter seal and filter when doing the glow plugs.

Reason for glow plug change is part learning, part trying to get rid of the white smoke. It's a bit hard on the start

Changing fuel filter and new gp's.would not make it worse...

Oscarklemo · 2025-06-12 16:09:18

Updste:

Today i took some more pictures of the original fuel filter, dint know if I should post them here or in a new thread, seems I'm opening lots of threads.

I also took some pictures of the glow plugs. Here they are

The glow plugs are marked in blue.

As you said kenbw2, the two on the right seems easy enough, the two on the left, behind the fuel pump, seems a bit tougher - though I think its doable without removing the pump.

Regarding the harness, is there any reason to change it or just brush the connectors with a brass brush, what could be wrong with it??? Its just cables and connectors

Also, Read somewhere to not only wait for the glow lamp to go off but to wait until the relay clicks, about 20-30 secs after the light goes off and it makes such a difference in staring the van. Waiting 30 seconds starts it right up. This would suggest bad glow plugs, or am I misinterpreting my van?

Gregor887 · 2025-06-12 16:39:27

Glow plug warms up still after click relay. Like a heater.
If you are going to replace them, start pouring them some rust remover now. It's easy to tear it.

This is my friend to unscrewing even the most rusted screws

I've never replaced the harness, I just put it back on. Don't even brush it - although maybe that's a good idea

Yes I've read that they could be at risk of snapping.

Ive started to treat them with WD-40 and rust removal today. Still waiting for the plugs.

Should be easier if the motor os warm when changing as well. (I.e. not running, but warm)

Ive seen some people put som kind of ceramic lubricant on the threads to keep them from sticking all too much. Have anyone had any experience from that and what product to use?

RegW · 2025-06-13 15:56:11

Just google 'injector and glow plug grease' and you'll get offered what is basically ceramic grease
you wont need to buy a lot if you decide to use it, just a small tube/bottle.

Getting the engine warmed up can help and if they're tight dont go mad at them
at the start, just try and 'work' them a bit first
ie slightly tighten and loosen them a few times as this can help break the grip.
This while spraying whatever anti seize you have on them.

I'll repeat the test suggestion I made above
If one or more is a bastard to remove but tests out fine, then it's better to leave it alone for now
until it does fail than break it

clean the connectors too

Hopefully they will come out nice and easy

Two out of four changed!

Went better than expected. Almost shat myself on the second one as I thought I snapped it, but it was just coming loose.

Tomorrow I'll give a try with the two on the left.

Oscarklemo · 2025-06-21 21:19:24

now they're all changed.

It was way easier than I anticipated, the Internet can really wind you up.

As for the one behind the injection pump, I borrowed a key from a neighbour, don't know what the English name is but it looks like this. Worked like a charm.

The second from left I used a straight key, and the two right ones I used an extender and a long socket. I had the fuel filter emoved but I don't think it really mattered.

I have soaked the plugs in WD 40 two times a day since a week back, as I'm commuting with the van.

All my white smoke upon starting is now gone and it starts much easier.

RegW · 2025-06-21 23:09:06

Well done, you'll be glad you did that come autumn and winter,
indirect injection motors can be a sod to start in cold weather without glow plugs.

That 'key' is what we call a 'ring spanner'
