Gurgling sounds - SOLVED!! Duckbill
I posted this as a reply on another thread but thought to post it on a separate thread because it may be of use to others.
The original problem was suggested to be caused by the duckbill drain issue of the AC....
So for about 3 months I have been wrestling with gurgling sound, suction sounds, rattles (like a loose wire or cable) clicks and something that sounds like a loose aluminum heat shield. This occurs mainly when the HVAC is on and only when moving.
Jacked the car up, inspected many times and spent at least 20 miles driving with my head bent over trying to isolate the problem. Tried replacing all the fasteners on the engine compartment shields, tightened all the heat shielding under the car, stripped away trims to inspect, banging and tapping endlessly and blew out the duck bill drain tube several times.
Finally, seemingly unrelated, I topped up the engine coolant - needing about a pint and everything is solved! Go figure! The car runs silently and perfectly. I would never have suspected this - maybe the gurgling, but all of those other sounds???
Solved!
