    Default Losing coolant but where??

    Hello guys, got the coolant warning light about 2weeks ago, when i checked it was 1-2" below the fill level on the coolant tank, i so i topped it up with a bit of water, and was keeping an eye on it.

    So booked it in the garage monday, said bring it back today wednesday and they had a look at it and pressure tested it, i was thinking a worn hose or a clip had came lose, but the pressure test didn't lose any pressure and the system was ok the chap at the garage said maybe it's a dodgey bearing in the water pump depeding on where it stops when the car does could lose coolant, said to top it back up and see if it develops any further because he didn't know what he could change at this stage to fix it and wouldn't want to bill me for a water pump if this wasn't the case, so luckily the garage we use for awhile now is ok and didn't charge us.

    i've noticed after a long or hot run i can hear the coolant tank hissing like it's pressurising again and noticed some coolant has came out the overflow from the back and onto the back of the engine in minumin amount real small amount.. and that when it's been stood shortly after a run some drops 2-3 comes from the front of the engine drivers side but could be from any other part because of the engine tray underneath and the run off..

    The only thing i can now think of is the coolant maybe boiling away and coming out the overflow as gas if this is possible and what would that mean, i'm not very mechanical but it's the only thing i can think of, any ideas?

    Thank you, i know it's long winded described best as i could.

    I have heard of the expansion tank spliting at the seam and only manifesting itself as a leak when the coolant heats up, expanding the tank slightly and allowing a slight escape.

    I'm sure its the seam that faces the bulkhead which makes it hard to find but I'm sure someone will come along soon and set us straight!

    Possible faulty pressure cap as well can cause coolant to bypass.

    I've had this, i replaced my coolant bottle and now it's fine

    Mine had a layer of coolant around the bottle's rim, thats how i found mine.

    Yeah that makes sense, i'll change the coolant tank and see how i get on with it, thought it would be something stupid when the more obvious pressure test had been done with no problems identified... was baffling me, will keep you guys posted after i get it changed and run it a few more times to see if that rules out the problem, thank you for the suggestions.

    Yes, I confirm! the coolant bottle leakage is a known problem.
    Check the joint between the upper and lower part of the bottle when the coolant is hot.

    i had the same sort of thing after taking the motor over an old track i use for fishing,
    noticed it was dripping from the front drivers side, i had to work the car hard as the track had changed considerably to loads of bumps and stack loads of sand,
    i thought the same thing, so scratching my head {excuse the pun}
    i left it and the header tank was almost empty within a few days,
    i topped it up and funnily never had a problem ever since,
    i think there is something like a drain hole at the bottom drivers side,{nut},
    check that as well fella, if its loose i think it can be a problem ,,,,
    im sure i will be corrected though
