So yesterday I started my car which had been sitting for a couple of days on the street. I live in Wisconsin and there has been considerable thawing, refreezing and thawing and refreezing (you get the idea) lately. Car started just fine but almost immediately I hear what sounds like water rushing out somewhere. I tried to convince myself that somehow there had been an accumulation of ice lodged somewhere that was now thawing but I don't know if that could be true. It seemed like it was coming from the passenger side behind the dash area. It continued to gurgle as I drove it. It seemed like if I turned the heat down, it slowed down. No warning lights. I checked the coolant and it's still there. Is there something terribly wrong?
