Got the car back today with everything fixed. Looks like they did clean work, however, the sound that appeared after they pressure tested the system last week was still present. The best way I can describe the sound is that it's very similar to the electric motor type sound you hear when you spray the windshield washers. It was happening every 30-60 seconds and lasted 5 seconds each time coming from the front of the car. I had the CSA come right out and get in the car so he could hear it too. He heard it right away but seemed to think it was normal, which it definitely wasn't. Good news is, after driving 30 miles or so the sound has stopped. Maybe air in the coolant system was causing the coolant pump to continuously run?
