1996 Chevrolet Tahoe LT 8 Cyl 5.7L
Why do I here chirping noise when my truck is idling in park and it gets louder when pick up speed in drive.
My mileage is 170,000 miles. I recently had the fan belt changed by Good Year. Then this problem occurred. The problem is a chirping sound and when I looked at my engine, it seemed to be near the pulleys which support my fan belt. Also my check engine light come on and off intermitantly.
Replace the serpentine belt. They dry rot and then chirp.
