    I made a huge mistake! but I think I solved most of it

    Yes I made a huge mistake but I have learnt a whole lot more about my vehicle which is a good thing(lots of things to learn as this vehicle is alot of firsts for me with things I haven't dealt with before like automatic, diesel, turbo) plus I think its still savable.

    So been dealing with my overheating issue and decided to give radiator a real good flush with the hose unfortuantly I had a brain fail moment and flushed the intercooler.

    I was lucky enough to realise what I did was wrong before trying to start the car and having it hydrolock on me. So I spent the remainder of the day pulling apart most of my engine removing both manifold (of which a mountain of water came out of) all glow plugs of which 3rd from front had water spewing from it for ages (guessing it must have been all the way down) I removed both radiator and intercooler and gave them a good blast with the hose as the front of radiator was covered in leaves, bugs, mud and just general crap (this I was unaware of as I didn't realise also in front of radiator and intercooler I have what I am guessing is a transmisssion cooler, its huge the size of both intercooler and radiator combined)

    I turned engine over with a socket attached to one of the front pulley wheels and even more water came out of the third cylinder I kept doing this until no more water came out.

    Am now starting to piece it all back together and once that is done and before I put glowplugs back in I figure I will turn it over with the key just to make sure no more water is in there before reinstalling glowplugs and hoping for the best.

    Is there anything else I should do before I try to start it as I really don't want to end up having it hydrolock I think I have taken all the right steps (except obviously the first one which caused the issue) but yes I am back here and seeking some advice (and probably some how could you be so stupid comments for such a stupid mistake) from those more experienced than myself

    What you are doing sounds good, also check the oil in case you got water in there as well.

    Oil so far doesn't seem to have any water in it but as I have completely removed radiator and therfore disconected the 2 oil hoses on the side which caused me to lose quite abit of oil I figured once its all back together I should do a complete oil change anyway

    With refrigeration compressers we used to use a light bulb on a lead to keep them warm during overhaul to keep any moisture away,or sometimes two leads and light bulbs.You could do this overnight or longer if you have time,with the glow plugs out,may help to get rid of some of the moisture.
    Maybe leave oil filler cap and dipstick out as well.

    Water will have seeped past the rings of any cylinder that had water so the oil will definitely need changing after its been running long enough to blow the last of the water out.

    I would get it back together and started as soon as possible to get the rest of the water evaporated out.

    Yes I have heard this hence another reason for me to do a complete oil change when you say running long enough to blow last of water out I am guessing your meaning turning it over without glowplugs in as if there was still water in and glowplugs installed wouldn't that cause hydrolock?

    I would not start it as the engine only has 4 glow plugs so there may still be water in one of your cylinders with no way of getting out.

    4 glow plugs is a fairly reasonable number for a 4 cylinder engine.
