    Coolant issues and over heating

    Hi all,
    This morning I was driving to work at 7am all bleary eyed etc in my 98 Astra.
    It was very cold and I noticed that the heaters were not running hot.
    I then noticed that the temp gauge was on max, I was on a road where it’s impossible to stop so I couldn’t pull over.
    Suddenly there was a funny sort of noise under the hood that sounded like popping or tapping and the heaters instantly ran hot.
    By this point I was 5 mins from work so I carried on.
    When I got there steam started to bellow out from under the hood.
    I lifted it and it was coming from the coolant reservoir.
    I waited for it to cool and then took the cap off….the coolant was pretty much empty.
    I topped it up with water and coolant and then went to work.
    At lunch the level in the coolant had dropped so I topped it back up and checked under the car for dripping which there wasn’t.
    Any ideas why? Could it just be that I am now filling the system and the level is dropping slowly as it fills up?
    I have checked the oil cap and its jet black and the car starts fine.
    Am I likely to have caused any serious damage?
    Cheers,
    Al

    your system was frozen somewhere from a lack of antifreeze and a rapid thaw has caused a burst within the system. you need to check all the cooling system.

    Thanks for the response.
    I am not very clever when it comes to cars.
    Could you give me a couple of ideas on what I am looking for?

    you'll be a lucky boy if you haven't cooked the gasket. check the coolant mixture if you have been topping up with water and it had already frooze you won't have any anti freeze. my water pump went as there was ice in the system so new timing belt too. don't drive until you check thde mix and keep eye on oil/water levels and the temp gauge.

    First port of call is to drain the existing 'coolant' and refil with a suitable ratio of water/coolant to prevent it freezing up again which is likely what happened.

    Vauxhall coolant should be mixed with water 50/50.
