How many miles on the car
Ok this is under the hood correct?Was the serpinting beltt tensioner checked?
Yes, under the hood. If they checked it, they didn't tell me!
Ok this is the most common issue and needs to be checked next along with the alternator and comprssor and power sterring pump.Most common is the bearing in the belt tensioner fails and causes this issue .There are also issue where the air boxx does not seal correctly making a similar noise.Print this out and have them check these issues next.These are the next steps.Hoped this helped.Positive feedback and bonuses greatly appreciated.
