    Hi everybody, can anyone point me to where on the engine block the correct nut is to drain the water from the cylinder block of a 1990 Fiat Ducato 2.5 turbo diesel? I have tried the Peter Russek manual but there is no diagram of where the nut to undo is.

    Thanks Pappajohn for such a quick reply. I have had this vehicle from new and flushed the block out a couple of times with a hosepipe through the thermostate housing and removing a radiator hose. I would like to drain it completley this time before flushing.

    Ok....:thumb:

    i had a feeling it might be something like that.

    in dont know where the engine drain bung is...sorry.

    you should really reverse flush the radiator though (if you dont already).....stick the hose pipe in the bottom hose and seal it with an old rag or something.
    youll get a lot more crap out that way

    if you look at it like fish scales.....scrape one way and nothing happens....scrape backwards and they come off.

    I like the description!! :Laughing:

    Having fiddled 'n flushed endless blocks over the years when still 'playing with cars'.......now i'd just bung a flushing agent in and let it go at that. But that's because i'm too knackered to fiddle anymore!

    It is quite rare to find a coolant drain plug on any blocks newer than the 60s:Eek!: rads used to have them too in the olden gays:Eeek:

    "Olden days"??? What "olden days"??:Eek!:

    Transit radiators still have 'em........thankfully! :thumb:
    A very useful and simple method of radiator draining.

    Plain common sense has unfortunately been replaced by cost cutting daftness and complex technology.

    Take the bottom hose off Autocruise.
    Probably as close as you'll get.

    A new hose while you are at it is good idea.

    Light vaseline on the inside of the first part of the hose either end is another good idea.

    Good luck.

    The only way I know of draining my 93 Ducato is to remove the bottom radiator hose. I try to catch as much coolant as possible to save making a mess by using a large washing up bowl underneath. But lots of it runs along the chassis etc.

    Many thanks to all who took the time and trouble to reply and advice given. I will do as before and drop the top and bottom radiator hose and reverse flush the rad, block and cab heater.
