K new 1999 s10 noise - water swooshing

So both me and my girlfreind have noticed a slight water swooshing noise that sounds like its coming from under the dash.
At first I thought maybe it was the hood/windshield drains clogged since it use to happen to my van all the time but for the life of me I cant find them on this thing.
Then I thought maybe it was coolant flushing through the heater coil but I have no way to tell. the coolant looks topped off.
anyone experience this?

Possible air bubble in the cooling system, so your thought process was in the right direction. Probably won't hurt anything, but if it's annoying you can usually bleed it out. Couple of way to do that.
