Why does my car make a noise when I accelerate?
Why does my car make a noise when I accelerate? Belt noise can mean the belt is worn or loose. Belt noise can also come when one of the pulleys the belt is riding on starts to fail. When the belt no longer moves smoothly along the pulleys, it makes a noise when the car is accelerating. The other noise you might be accustomed to is that of a loud exhaust system. What kind of noise does Silverado Z-71 make? My wife's truck, 2005 Silverado z-71 with a 5.3L, has this weird noise it's been making the past few days....
