    Hi all
    Im having trouble with my parents car at the mo and im having trouble getting to the bottom of it
    noticed that coolant had gone from the header tank after plooms of white smoke came from the exhaust, the car was running fine but smoking like dot cotton. After a bit of diagnosis the egr cooler was at fault replaced it and got it running. it was still smoking but no coolant was being lost, took it for a drive and it felt down on power and still smoking
    I started it up this morning and no smoke took it out and when it got up to temp would smoke again more so on idle?
    I must add the temperature has not risen above normal once

    many thanks

    If your cat has got contaminted with what was leaking as it sounds like it has it will take some time for that to burn of i would take it for a good run and get it nice and hot that should clear it

    Is it white smoke or a hint of blue? Could it be burning oil?

    It not getting up to temp is probably a different problem it will be the stat or temp sensor more then likely

    It's white smoke that's pouring out of the back it smells like burning coolant
    the car gets up to temp and doesn't overheat and it's not losing coolant as far as I can see
    we have also changed the thermostat :( it's weird

    if a lot of it got into the system that will take a fair while to burn off

    If the heaters are not always hot that could be a sign there is an airlock it may be worth giving the coolant system another good bleed and do so with heater set to hot

    Gave the car a good run this morning and the smoke has cleared now
    been to the local garage and has been diagnosed with a dodgy water pump
    so it's staying there to have cambelt water pump and full service
    all should be well we hope
    thanks to all for your help

    Cheers
