Okay now that you point out that the coolant level is fine and you're still getting the warbling / gurggling noise from the passengers side, I would suggest / guess that your heater core is going. That was the warning sign on my Taurus at the time, just before I dumped it. Are you smelling anything sweet coming from your vents at all? :unsure:
