watery sound when i acceralate my car, whats deal guys?

 

Mine did that too, when I swapped out my radiator. I could be air bubbles going through the heater core. Mine disappeared after a day of driving. There's no bleeder for the coolant system, unfortunately.

I read somewhere that if there's bubble in the heater core, they'll always be there. It wasn't so in my case. But it's something to think about if the bubbling continues.
