    Default Serious ammount of coolant loss. HELP Please

    Hi Guys hopefully someone can help.

    I have a 2.0Dt1 on a 03 plate, i'm loosing a huge amount of coolant from the header tank, if i do a 10 mile trip i can loose nearly the whole tank full. I have changed the thermostat, header tank and cap. i don't think there is a propblem with the water pump as there is no rattle coming from it and the return pipe into the tank is flowing nicely. but i have noticed that air escapes the header cap as if there is too much pressure in the system.
    The heaters run hot when the engine is at fast idle or if i'm driving. but when the car is at idle the air goes cool.
    I can't find any leaks in any pipes. there is no mayonase in the oil cap or on dipstick and there is no oil in the water.
    I've flushed the whole system out today and added some rad weld ( last resort i think). I've had the car idling for a good hour and water seemed ok. took her up the A41 and within 2 miles the temp gage shot up to 100deg. again i lost all my coolant.
    There was no white plume of smoke out of the exhaust so i realy don't think it's the head gasket, i have noticed the that the top of the rad on both ends is cold. so i'm thinking i have a huge Airlock.
    When i got to my workshop i filled the header tank up with water again, and ran the car at fast idle for a couple of mins. the return pip was runing constantly then i had a couple of splutters and i think what was air came out , the water rose up a bit then droped down. i did this a few times and i think the air has gone. Toped the car up with water again and drove the 10miles home on the A41. got her to 70mph and everything seemed ok, heaters worked driving and at idle and the temp gage was at a constant 85. Just around the corner from home the water light came on again but this time i only lost about 10mm of water. If there is a airlock still how do i remove it as on the 2.0DTi there is no air screw on the rad pipes. i have tried filling the expansion tank with water and removing the heater matrix pipes.
    I'm realy at a loss. if it is the head gasket i've been told it's a +£800 job , which i don't have. I've done loads of heads on my old fords when i was younger but havn't tackled a new deisel before, how hard is it?

    Thanks for reading, apologies for the bad grammer and spelling ( not my strongest point)

    Hopefully someone can help

    Have you checked the oil to see if there are water droplets in the dip stick.
    Is there a hose high up on the engine you can take off to "vent" the sytem. Also have you tried running the car (stationary that is) with the filler cap off the header tank, try this for a while it might "vent" the cooling system.

    Hi Ed

    Thanks for the reply. I did check the dipstick, no water on there.

    I removed the top radiator hose ( the small one that vents to the expansion bottle) and sucked ( it tasted horrible) water out and let it run away for a while. This was after the engine was hot, so the water from the rad should have been hot as well. it wasn't it was very cold. then after about 1/4 of the tank went down it turned hot, which leads me to believe i have a air lock in the rad. maybee it's blocked up and i need to remove it and give it a proper flush.

    Does anyone know how easy this is as i have the aircon rad on the front, does this swing out of the way or do i need to remove it first and then regas my aircon?


    Cheers guys

    What about removing the top and botton hose from the rad" and putting a hose pipe in say the top and try flushing it for a while. Do they still do fad flush? I have used this before. It is supposed to clean out the cooling system prior to refilling with antifreeze. Might be worth giving that a go, just incase there is a blockage somewhere.

    Mate sounds like either a blockage or a definate leak somewhere, have you tried running the car to hot and looking for leaks with the bonnet open?

    From what you say its got to be a leak, you should check all your pipes when hot to see if any are still cold that should be hot!

    Well it sounds to me like a head gasket I'm afraid mate. Top your header tank up and get the engine to operating temperature. CAREFULLY, remove the header tank cap and give the enigine a good few revs, if the head gasket has gone, the cooling system will be pressurised by cylinder compression and you get the volcano effect out of the header tank neck. Alternatively, get an empty clear bottle (a half litre lucozade bottle with the label removed is ideal, top up your header tank to the top of the filler neck so its about to overflow basically. Now fill your bottle with water to two thirds full and very quickly invert the bottle and put the bottle neck into the header tank tank neck so that the bottle is upside down. Now get someone to rev the car and watch the water in the bottle. Air bubbles coming up is a sign of a blown gasket around the water jacket. HTH

    To loose that amount of water in such a short jouirney, if it was a leak, you would most definately see it

    Hi Guys did a rad flush today, all came out clean. i've had it running hot all morning going over it today. can't see any leaks anywhere. had the bottom pan off and crawled under and over. I defo think it's a blockage, which is building pressure and i'm loosing it from the header tank, but tbh i'm not sure.

    Realy frustrating as we're supposed to be going to by brothers for christams in portsmouth and i can't even get out of aylesbury lol

    Think you could be right Gary.
    If i get her up to operating temp , remove the cap. ( get a slight bubble from pressure ) thought this was normal though as it's a pressurised system?
    give her revs and the water runs smoothly for a while, then i get a slight volcano. i took that as air escaping the system? probably not though. I'll have to get a sniffer test done i think.

    Def not mate, the volcano thing is cylinder compression pressurising the system. Yes it is a pressurised system, it has to be to raise the boiling point of the water and as such, if you reemove the filler cap when the engine is hot you may get a slight loss of water but mostly hissing if you do it slowly. once the natural pressure of the system is vented, the coolant should remain steady as you rev the engine with maybe a slight dip as the water pump speeds up and the impeller action 'suck' the coolant around. If it then wells up and gushes over the top......not good.

    By the way, if your system has been drained, when you refill it, make sure the heater control in the car is set to hot to open up the heater matrix valve. If you don't, as soon as you do open it, it will cause an air lock, which usually manifests itself as overheating and a rubbish heater

    Yea you can get the sniff test done mate but i told you about the bottle trick so you could do a quick diagnosis yourself first. At least you'd know, but it does sound very head gasket

    My first thought was Head gasket. But you sort of ruled that out yourself. Is there an undue amount of condensation from the exhaust?.
    I had a Granada that the head gasket went on. It must have gone between the cylinder and the water jacket, as it ran perfectly. But if I left it on tick over it looked like a kettle boiling if you were behind the car.
