I noticed that the coolant was coming out of the radiator fill hole like ti was burping and spilling out. So we added more water and after a while I decided to drive the car home for about 4 miles. The water temp gauge was at 3 bars all the way home, when I got home there was steam coming out of the radiator. I also did not know at that point that these cars required a coolant bleed just like the BMW's etc.

I just ordered a new radiator now I am worried about a head gasket leak. Is the burping of coolant a result of a blown head gasket or because there is air in the cooling system? Thanks,
