Question about 2007 Chevrolet Cobalt Coupe
It is part of the waste gate just above the gas tank. It periodically checks for leaks and pressurizes and releases. Gives a ticking noise when it does this. Not a problem and GM is aware of this and said its normal on our cars.

I own a 2007 Cobalt, and I have never experienced this before. Mine currently has ~15,000 miles on it, and the only ticking noise that I have noticed is when I first start my car, and I idle I sometimes hear a ticking noise that "ticks" about 5-6 times and it comes from the rear of the vehicle. But it only lasts for about 3-4 seconds.
I have heard other vehicles make this sort of ticking noise after they are shut off, which is attributed to what you were told about during the inspection. Metal makes noise as it expands and contracts, and cars generate heat, which causes the metal to expand and contract as it heats up and cools down.

I would agree with it being the car cooling down im not sure if it is common on all cobolts though
