    Hello again...

    I was driving today, when the coolant light warning come up on the dash- i picked the car up about 3 weeks ago and it was serviced, and the water was topped up. Ive covered probably about 1000 miles, and the car has been fine, stayed at 90c every trip, for the whole journey.

    When i checked the water after the light came on, it was well below the mininum. I looked for obvious signs for head gasket failure, but there is not water in the oil.. or vice versa - also there has been no loss of power etc.

    I've read some where about the "bleed screw" breaking, but from what i can that too is fine. There is no signs of leaking in the engine bay either...
    Where is the water going; any ideas?!

    What was done at the service? As its possible its cleared an airlock maybe?

    pjmspeedy Dude, what's mine say ?

    Squezze the top pipe that goes from the top of the rad to the metal tube that the bleed screw is in and listen for air being pushed up through the screw.

    I would even take the screw out to double check. I have a couple in my garage so if you need one let me know and I can pop it in the post for you.

    Okay, it was only an oil change, and the other usual bits. The water was only topped up..

    You should have the cooling system pressure tested while both cold and hot, to determine the cause of the coolant loss.
