After running my engine for a while (2l Dti) I noticed that there was a slight hissing sound, of air escaping (?), from the expansion tank . Is this normal or do I have a problem ?
Sorry about the title, could not resist it !

Hi dc
are you having to top up the coolant,you could have a faulty ex tank or cap,the worst outcome could be a head gasket failure.is the temp above 85 when you are driving.first job check the seal on the exp tank cap.
