There was a loud chirping noise when the car is cold. I changed the water pump, idler pulley, belt and the sound still continued. I suspected the camshaft synchronzier and when I took it to a local mechanice he confirmed the issue. The part was changed and the sound immediately went away.It was difficult to pinpoint on my own because the sound would lessen dramatically once the car became warmer.
