"are you sure the sound is behind you? look behind the roll hoops on either side of the engine lid. are the drains clear? is there any standing water?"

The sound went on for 5+ minutes, which would mean a fair volume of fluid was moving around and making noise. I just did a quick drive, the temp had warmed up to 22F, no puddles under the car and no trickling sound, curious...
