Nissan March Ak12 Water Sound Coming From Dashboard When Accelerating..

[rskoora]

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 .

A possible cause is that your AC drain hose is blocked and water from the evaporator gets accumulated on the tray underneath it. The high pressure undercarriage wash from the service might have bent the drain hose. Just my 2 cents.

Edit:

If it was an air pocket in the cooling system, the sloshing sound would have disappeared after the car reaches operating temperature because the valve in the radiator cap disperses all air out of the system.
