I've only noticed this twice last month. Both times it's happened it's been about 20 degrees out and the car has been sitting for 3-5 hours. Thought it was a belt squeak but the sound is coming from the driver's side of the engine (in the valley between the engine and the battery). Both times the noise went away after 2-3 minutes. Any ideas?

The car is a '98 Mystique LS with 65K on the odo.

Thanks,
Dave
