    Temp Problems!!!

    Guys,
    Looking for a wee bit of help here.
    I drive a 94 16.i Astra Cesaro.
    I just drove to work (nightshift) and my cars tepm sat at zero for 90% of the journey (45 miles).
    On the last 10 minutes the temp gague raced up to 100 degrees, but the blowers were cold.
    I thought , "cool, no water".
    But no, When i got to work i slowly took the cap off only to be met with lots of hot foam (like soapy bubbles, but not).
    Anyone got any ideas of what this could be, and is it likely to cost lots of money to sort out?
    Cheers

    Davie

    Firstly, do not ever open a radiator cap when the engine is warm/hot. You'll scauld yourself with hot radiator water.

    Secondly, pressurised water in the cooling system makes the boiling point of the coolant to be over 100 degrees. The additivies in coolant will make the boiling point even higher. Unless you are losing significant power (due to pinging etc), I would not worry too much about it.

    Cheers for the reply, but I am worrying about it.
    Since posting i've been told that it's the head gasket thats gone, and it's the oil mixing with the water thats causing the foam.
    I've been back out to the car roughly 3-4 hours after stopping here and there was very little water left in the watter bottle.
    I topped it up and let the engine run for a minute without the cap on and you could see the foam starting to build back up in the water bottle.

    Is it maybe worth flushing the radiator to clear out all traces of this foam stuff?

    It sounds like a headgasket or something actually.... check the oil, see if it's foaming or miky as well..... either someone put soap in your radiators or it's a head gasket

    Yeah, that's a sign that your head gasket has gone... You'll also notice a loss in power as well.

    Ubugger, I thought it was vegetable gum that seals the gaskets? But failing that, you'll have to bite the bullet and get it done properly.

    Just be weary that whenever it's hot, just take it easy on the car coz pushing it when the engine and ambient temp is hot is a receipe for doing a head gasket.

    There is some "bars radiator sealer" that may do the trick, there are a few things you can use before spilling out on a headgasket, not hugely expensive, but still money
