first of all I must say I'm new to the forum. I'm only 18 and have my license for about six months. I have basic mechanical knowledge. recently, i bought my first car which happens to be a 1.0 fire uno. i bought the car around a month a go. three weeks ago i noticed a warning light on the dash. it looks like a sprinkler. when i filled the car with a mixture of water and antifreeze it went away. for about 20 days it seemed fine only to reappear when driving on the autobahn. car is mostly used around town and the light doesnt appear when driving slow and for short distances. however there is like a hose missing on the engine which purpose i dont know.
