Technical Draining the Diesel filter

[rmbatty]

Hiya.
Can anyone run me through the correct procedure for draining water from the Diesel Filter on a 2000 Multipla 1.9 JTD?
There does not seem to be much space beneath the filter so do I undo the three 10mm nuts at the top?
Regards
Richy

Assuming it similar to other JTD filters :- (i.e. bugger all access)
Remove the wiring on the side (fuel heater)
Remove the pipes (feed is quick disconnect, other two pop open the clips)
Unbolt from bulkhead,
Remove wiring from bottom,
take to vice or similar then open the drain at the bottom.

Hi there,

I keep getting the message "Humidity Dies Filt" so I presumed that my diesel filter needed draining, so I followed your instructions (well Mr Fwoggy did) but ours seems to be different, all the bolts and leads are where you say they are but the actual filter just has a screw off cable thingy on the bottom. Do we remove this?? Because when he started unscrewing it diesel started spewing everywhere, and it hasn't fixed the problem either because just after I put some diesel in it the same daft warning appeared. When I phoned the local Fiat garage the woman in servicing didn't know what the heck I was talking about and told me that I would need to bring it in for diagnostics. But the workshop manager said try replacing the fuel filter... what do you reckon???

Thanks in advance.

In my handbook page143(checking fluid levels,diesel filter) shows what to do I own a 1.9d scudo van and IF it has anything similar , that cable thingy of which you speak directly below the filter is a drainage pipe. You could try loosening the plastic knob at the top of the pipe a few turns with a clean jam jar at the end of the rubber drain pipe. diesel should come out of the bottom of the pipe so you can see if there is any gunge/ water in your diesel filter. Then retighten the knob carefully.

But niether fiat HQ or my local dealer had any knowlege when phoned and the dealer seemed to think it odd that the book says drain it every 5,000km
It also states that you should have this done by a dealer.

And Of course YOUR multipla might be different from my scudo engine.

On my 53reg Multi (which I've just changed the fuel filter on) there is a cable at the bottom which is attached to the filter drain - no drain hose/pipe though. The replacement filter was supplied with a basic drain tap so I had to swap that tap for the one with the (moisture?) sensor already fitted to the car and of course got diesel everywhere

Just done my 02 diesel filter suprisingly easy job
1. remove the 2 electrical connectors at the top.
2. undo and remove the 3 pipe connections, watchout for the washers on the inside end of the bolts.
3. undo the 3 (I only had 2) 10mm nuts that hold the unit to the bulkhead.
lift the whole thing until the wire underneath is accesable.
4. disconect the wire from the bottom of the filter at the connector partway down the cable.
If you do it this way you will get the minimum amount of diesel in the engine bay, once removed hold over a container and upend the filter it will now drain the filter, unscrew the plastic bit on the bottom, this needs to be screwed back onto the new filter, I used a oilfilter wrench and unscrewed the filter.
To but it back together reverse the above.
I gave the electrical connectors a squirt of WD40 for good measure.
Once back together turn over the engine until it starts, it self-bleeds so thats nice and easy.
Job jone, I did mine in about 10 mins.

I have had problems with my diesel engine. Not starting when hot, then another symptom of the engine cutting out occured several times on the motorway - restarting Ok after about 10 minutes. As it alwys seemed to happen when engine had been working hard, a blocked fuel filter seemed a reasonable idea. I therefore tried replacing it (usining very helpful info above) only to discover that I had been supplied with the wrong filter. Replaceing the old was OK and it soon primed and engine started OK. When I got the right filter I set about the process again. Unfortunately the engine did not start this time. I got it towed to local dealer who tells me that the injection pump need replacing at a cost of £950! I feel that I may have done somthing stupit (as I don't believe in coincidences), but couildn't find anything. Could air have got into the pump the second time and caused a problem?

I would guess that your original symptoms are consistant with a worn pump where the clearances open up when it gets hot.
As red1leader says it should self bleed and prime (at least it always has in my experience) so unless you've done something very unlikely such as putting something in the pump inlet pipe I'd reckon that the effort of bleeding/priming was the final straw for the pump. I hope I'm wrong though for the sake of your wallet.

I spoke to the dealer and as the Diagnostic pointed to the pump, it must need replacing! I just hope it is not some bad electrical connection. It is a bit worrying if an injection pump is worn after only 89,000 miles and 4 years as mine seems to have done.

My pump needed replacing after 69000. Loosing confidence in fiat, just seem to cost me money
