Hello, I bought a Hyundai Accent 2001 Coupe a couple of months ago. I notice this winter that when its cold or humid there is a whirring/scratchy/screeching noise that comes and goes away. This sound is coming from the belt side of car. At times, it doesn't sound the same as a screeching belt. The belts are not loose and they do not appear to be wore down. The car has 55,000 miles and, I am the second owner, the timing belt was never changed. I am planning to change it at
60,000 miles. Do you have any ideas what this sound might be? Is this a sign that the timing belt needs to be replaced?
Thank you for your help and advice.
