You could have piles of rust running around if its never been flushed. This dirty old crap could be blocking waterways in the head what would be a disaster. Someone could have mixed red and blue antifreeze what is a no no. I have seen rusty water cover the temperature sensor in the past t a state where they give false readings. Me i would take radiator hoses off and fully flush the whole system and dont stop till you see clean water coming out. It is safe to run without a thermostat just your cab may not be very hot. There is the possibility you have a duff thermostat. Do the boiling water test in a cup test to confirm. Other option if bin the heat controlled fan and rewire it to either have a switch in the cab and remember to turn on/off according to temp gauge or feed it to an ignition wire and have it on constant.
Thanks for the info ill flush the system this weekend and see what she's like. I did think to wire a switch I for the fan but then thought we'll indont know when the things running hot as its always on 60 when It warms up? ill test the new thermostat aswell and make sure it's not a dud. Thanks for the help

Are you absolutely sure about the thermostat being the correct one?
How about trying it without a thermostat. Sounds like the hot water isn't reaching the temp sensor.
Got the thermostat from euro car parts. They had two variations so I just got them both to make sure I had the right one as I didn't know exactly which was in the van. It never used to do this then one day just started to run cool. Replaced thermostat with the same as the one that came out.

Cant see the radiator bursting if to cool. My money is on a some form of blockage or part blockage
Thats what I'm puzzled with. It can't be cool stood in traffic ticking over and no fan kicking in but the gauge says it is. I've plugged scanner tool in to check gauge isn't faulty and it's reading the same temp as the dash.

Hi there, my dispatch 1.9d on a 2005 isn't running above 60° and the fan never kicks in. Had it in for MOT and it burst the radiator on the ramps and was told the fan wasn't working. Replaced the radiator and checked power to the fan and it spins. Thing is the gauge never rises above 60 no matter what driving conditions I'm in . If I unplug the temp sensor the gauge goes up and the fan kicks in. This is the 3rd temp sensor I've had in to make sure they havnt been faulty. Any ideas why it's running like this? Also thermostat has been replaced aswell as coolant. Thanks chris

Outcome to new coolant temp sensor and coolant is, wait for it............................... done absolutely nothing? temp gauge still says its over heating kn a cold start and after a minute it goes to zero and stays there. I've bit the bullet and had enough love the little slug of a van but its starting to do my head in. Changing engine next week.

temp sensors usually fail internally, however if its working on the dash then it cant be that thats faulty
have you tried unplugging the mass air flow sensor? again a pretty useless thing on a vehicle without a turbo but i guess it helps calculate EGR.
best thing with these engine is you can just pretty much just keep unplugging things till it works... not sure on the DW8 but on my DW10 (HDI) it only needs the fuel pressure sensor, crank and cam shaft sensors to run and hell once its running it does not even need the cam sensor!pretty sure on the DW8 you can even unplug the damn injectors and it still runs.. all be it rough haha
Yeh tried the mass maf and no different. Been and got a coolant sensor to change and change the coolant while I'm on. I belive sensor is faulty as the gauge is all over the place sometimes doesnt move sometimes up in the red from a cold start. Will get it done and see what the outcome is.
#7 Re: Maintenance » Dispatch being a pain » 2021-04-05 18:13:32
hmm that sounds about right for a failed one.. i sadly do not know where it is on the DW8, however i would look above the bell housing. its a pretty common place.
just note that you'll get coolant leaking out when you change it, if you do it quick though its fine.. hell if you dont know the coolants history class it as a flush and replace with new. just uses standard OAT coolant.
Ive found it and took it out and had a look at it quickly. Gave it a clean up and put back in as no where open to get one right now. Stop light came on dash upon starting. Temp gauge on zero but red light on to say its at 110. Started van stop light still on so moved forward and its gone out. Temp gauge stopped working. So plugged on scanner. Still -40 on startup when warmed up for ten minutes its sitting at 41. A mate of mine owns a scrap yard and has a dw8 on the shelf for £150 and wants £150 to swap it straight into the van. Says it came out of a dispatch and has 100k miles on it. I'm tempted to just do the swap as I can see this being a money bit changing parts all over the place to get back to normal.

hmm strange one. have you changed the temperature sensor yet?
they can fail and when they do they usually tell the ECU the temperature has gone absolute zero or thermonuclear... which can cause running issues heh
Hmm strange you say this. When I plugged it into the reader and had a scroll through the temp was reading -40 on the code reader. Any pics of the temp sensor?

At what you are saying i would be more prone to think (Im no mechanic) its the valve seals. When parked overnight the oil will seep down into the top of the pistons. When starting up you will burn it off and be fine for the day. Did you take them plugs out a cold engine? If so that may explain my theory more. Did you pay much for the van? You may end up with a money pit but as you need it for work you will keep throwing good money at bad. Get a compression test and see what the pros say. You could end up paying for that van two or three times over. I paid 800 for mine and apart from the odd starting issue its been great.
Took van for a good drive out so engine was hot when plugs came out as I done oil and filters at the same time. All 4 plugs came straight out not a problem with any of them. Van cost 700 and was only meant to be a stop gap van to get me started and its sods law it will cost me a fortune?

air intake was took out and egr was unscrewed and cleaned out aswell. Egr had about 5mm of gunk on the inside walls of it so that was all cleaned of and intake sprayed with carb cleaner and washed out and left to dry. As for oil usage I've had the van just over a month and I havnt noticed any oil usage at all before I changed oil it was sat in the right place on district and after service its sat at the full mark and hasn't moved.

No.
When i changed mine last year i had one with slight oil on it. You have either buggered rings or valve seals. Is that 100% oil or diesel with the general engine soot/gunk mixed in? Oil would explain your smoke and crap starting. It may also be oil water mix indicating a head gasket. But all four? Hmmm. Any oil in coolant?
I would say its more oil that diesel its thick on you finger to touch. Coolant is clear no oil at all in there.
And yep all four where exactly the same when I took them out.
Would this be the oil burning off on a cold start then causing the smoke and when it's gone its running OK but down on power because the head has gone? Going to have to get it booked in as its needed right now. I'm guessing the head isn't going to be a cheap fix either.. absolutely no luck with cars/vans.
Once warmed up it doesn't smoke at all and is fine on a flat just gutless on any uphill gradient. Can be sat at 60 and hit a small hill and its down to 2nd gear in no time and 25mph.

Based in Durham area. I've just had the timing belt cover off and noticed the belt has about 10mm play if I push on it. Could it have jumped a tooth? Wouldn't it be missing all the time if it had? Going to get a code reader this afternoon and see whats om there.
I would say aye. I have a chain on my Convoy rather belt and if that jumps the fuel timing is out also causing it to run like a bag o shite. MPG would be down also. I average 34/5 MPG with the same engine as you
20 litres is getting me about 120 miles
I've just had a code reader on it and no fault codes to show. Is it normal for all 4 glow plugs to be gunked up with oil?

Hi I'm new here.
You have all probably heard this a million times before but here goes. So I bought a 55 plate dispatch 1.9d as a first van to head me on my way trying to start my business off. Problem is ita started to be a pain.
130000 miles
Symptoms are it will start up no problem at all every morning from cold but after about 15 seconds of running fine it starts to missfire and puff out blue/white smoke until warm then it clears and runs fine although it does feel to me like something is holding it back slightly. I know these vans are slow but in down to 25mph on hills with very little in the back of it. After a gear change it kangaroos slightly until it picks up the revs aswell.
Things I've done so far
New filters all round and new oil
Blabked egr valve
Tightened throttle cable
New backbox as old one was rotting
Changed all 4 glow plugs. Every one I took out was thick with black oily sludge?
New rocker cover gasket
And ran injector cleaner in the tank for about 400 miles and its still the same.
Also every now and then when I go out to start it from cold temp gauge is up in the red and the stop light is on but this will clear when I start to drive it?
Any help appreciated as I'm at my wits end and have limited money available at the minute until business gets going.
Thanks chris
