Friends,
I have a nissan march ak12 auto car, so today Morning I have noticed that under acceleration from a stop, there is a noise that sounds like water sloshing around or being pumped around somewhere behind the dashboard totally wired .before that very recently i have done a full service including oil change / atf change/ coolent flush and refill.
Moreover I have done some search on internet and most of them had same problem and they are saying that could be air pocket in coolant system could it be a true?
any thoughts would be appreciate.
Thanks .
