97 A4--says coolant is low...add some then when it is shut off...it will leak from the overflow. It never looks like there's enough in there but if you add, it will come out the overflow after shutdown. I do hear aslight gurgling noise in the dash. I've just had the cooler replaced. Any suggestions?

 

air pockets. but are you overfilling or is the level actualy low in the fill bottle

 

the cooler? I assume you mean the heater matrix or the radiator ^defiantly air in the system^ ensure you have the heat turned to max so it bleeds the matrix as well as the engine and radiator

 

not real sure what he means either could be the heater core he was meaning
