Need some advise guys asap
i was driving round today for about 3/4 hour with no problems etc then i suddenly hear a beeping and look down and dis is flashing a big red thermometer and the temp was 120c, so i pull over and steam if flying out the side the bonnet.
so i check the fans and they both on, so i wait for it to cool a bit then drive slowly home with the heating on full to sap some of the heat, which worked but you could hear the pipes were bubbling from under the dash.
i pop the bonnet at home and its still bubbling and the pipes are very hard so i release a bit of the pressure and let it cool down again until it gets to the 90c im used to seeing.
BUT now i have no heat coming out the heater, and when i pull the pipe of the back of the matrix where you can bleed it theres no water, and it doesnt appear to be being pumped round and the main radiator is also cold or just luke warm.
Also when its ticking over i can now hear a strange noise that i cant describe or work out where its coming from
Ideas? im thinking water pump but hoping its not.
