Engine Cooling problem
2002 Fiat Stilo Front Wheel Drive Manual 79000 miles
i have a 02 fiat stilo 1.8 dynamic.
today I was about 5-10 miles from home. On my way back I went on the some carriageways going a top speed of around 50-60. I was going to the local asda before I got home. Just as I was down the road from the asda car park I started to smell a burning smell. Then about a min after I was at the traffic lights waiting to turn into the car park when some steam came from under the bonnet. I turned into the carpark and pulled up to check. The engine heat gauge in the car was at half so it didnt over heat. Soon as I stopped loads of steam came out from the engine. I popped the hood and saw the engine coolant was totally empty. I just had the car serviced the end of june and no there was enough in there. I let the car cool down and left it there for 2 hrs. Then I got back in to go home and the engine was making a loud noise and sounded worse then a tractor. Soon as I got home I put some more engine coolant in but I only had a little bit. All the car shops are closed until tomorrow. Will filling the coolant be enough or has the engine had it? Help please im really worried
