Hello: Long time lurker, first post I believe. I have owned my 850 Sport Coupe for 7 years and have gone through the car mechanically, it is a fairly “stock” car. Yesterday I embarked on a 147 mile trip and about 70 miles into the trip the alternator drive belt was thrown / broke. It was a Gates belt with about 2,500 miles on it and about six years old. The belt had a “notched” surface as opposed to a a “smooth” surface. I know the belt was tensioned correctly. Any comments? I read in another forum this cars are prone to throwing belts. I had been cruising at 5000 rpm for about 35 minutes. Ironic to think that out of all the things that can fail on one of these cars it was an American made belt! I have been driven Italian cars for 40 plus years, fist time I have called a tow truck in decades! Thanks in advance for any suggestions.
