I recently went to a Porsche dealer because they had replaced a broken alternator belt and power steering belt. They disconnected my air conditioner compressor and said that it was freezing up and that is what caused the belts to break. They charged me $550. I picked the car up in the evening after the techs had gone. Driving home I kept hearing squeaking, so the next day I took it back. They told me that the alternator bearings were bad and that I needed a new alternator and it would cost $1400. I decided not to have it done there and I went to a place that rebuilds alternators. He told me that my belt was too lose and it was the belt squeaking. He showed me that he could, with the engine turned off, turn the alternator easily by hand. Since I was there and my 968 has over 140k miles on it, I decided to have the alternator rebuilt anyway for $110. He put it back on and it seems to be fine now except my air conditioner no longer works. My question is: was he correct in that the belt was too loose? How do I know now that the tension on the belt is proper? Is there a tool, or should it flex a certain fraction of an inch when pushed? thanks
