2008 Volkswagen Jetta Question: Whinning noise @ serpentine belt area.



jay830, New Braunfels, TX, August 25, 2011, 16:12

Notice a whinning noise coming from the serpentine belt location. Noise mostly during idle & acceleration. Was told by a friend that owns the same year Jetta, who also had the same problem, said that the Idler pulleys (upper / lower) & both tensioner pulleys where going bad. I went ahead & changed out the pulleys & serpentine belt but still getting the whinning noise. Any suggestions of what might be causing the noise?

    My guess would be belt tensioner needs replacing,or waterpump is going bad.
