The Dispatch | Expert | Scudo Hub

Hello!

I am having some trouble with my 2001 Citroen Jumpy/Dispatch with the 1.9D DW8 WJZ engine. When started cold there is white smoke coming from the exhaust and the engine runs really bad, it misfires. It wil drive, but these symptoms stay as long as the engine is cold. As soon as the engine warms up it seems to run just fine.

Usually you would start by changing the glow plugs with these symptoms, but I don't think that is the problem because right before these issues the engine had some timing belt problems. While driving the engine suddenly started to run terrible. AA said the engine was probably done for and brought the car back home on a flat bed. I found that the bottom crankshaft cog bolt was loose, causing the timing to be off. The belt was changed in 2021 and had only done about 30k kilometers since changing. I thought that would be the end for my little Jumpy, but tried to revive it anyway. After tightening the crankshaft bolt and retiming the engine I ran the engine for a bit. After a few initial misfires (some unburnt diesel left from wrong timing?) it ran great. So I ordered a new belt, fitted it, and here we are now.

Now I don't recall any white smoke when I shortly ran the engine after retiming it for the first time. I do think it ran better than it does now. But I am second guessing myself because I only ran it for a little while since there was no auxiliary belt on the engine.

Here is where I would like some input from someone that maybe knows a bit more about these engines than myself

- Is it likely that I fitted the new timing belt (slightly) incorrect causing these problems? I did recheck the timing before putting everything back together, but I am no mechanic by trade and am human. I think that if this would be the case the engine would also run bad when warm.
- Is it possible that maybe the valves did touch the pistons causing damage?
- Is it perhaps not at all related to the timing issues? There were no cold start issues prior to the timing incident.

Thanks for reading and any tips you can give!

Edit:
Here is a YouTube video (not mine) of someone having the exact issue on the exact same van as I had with regards to the timing belt: https://www.youtube.com/watch?v=7p_TDIbKyUM&t=362s
Engine start at 0:33. Talk about loose crankshaft cog at 5:02.
He decided to replace to engine. I decided to try and save mine.

To bet clear. This is NOT the issue I have now. The cold start problems are right after replacing the timing belt en fixing the timing.

Hello!

I'm having a little trouble when it comes to changing the coolant in my 2001 Citroen Jumpy/Dispatch with the 1.9D engine.

There is currently orange coolant in the engine, but according to everything I found online orange coolant is only used is really new Vauxhall cars. So it's not supposed to be in there. Not problem I thought! I'll just buy a different coolant that is supposed to work according to the internet and I will just replace all off it. So I bought blue antifreeze from Kroon-Oil. According to the Kroon-Oil website and autodoc registration plate checker it should work just fine in my van.

Now that I want to start im doubting if this is a good idea. I probably won't be able to remove all the coolant, I can't even find an engine block drain bolt. So what I would have to do is remove the bottom hose from the radiator, not get all the orange coolant out, and the fill it up with the blue stuff I bought.

Will this be fine or is this a terrible idea? Should I use a different coolant? Kroon-Oil also recommended a yellow coolant, perhaps I should use that since the colour is closer. What is currently in the car certainly is not yellow, but orange. 

Curious about what experiences you have with this! Many thanks.
