Porsche

After living with a noise that seemed to come from the right front of the car, I finally dug in and did some research. This noise is described as "howling" you'd hear when you blow air across the top of a bottle. For me, this happens at speeds between 25-40 while running at a constant speed. In fact, one way to confirm is to see if the noise stops when accelerating (it does).

In Feb 2016 the alternator failed in my Porshce 2001 996. My mechanic was on vacation. I used Mobile German Auto Works here in Santa Cruz. They replaced the alternator and evidently replaced the coolant bypass coupler. The repair cost over double what it cost to replace it the second time.
