About a week ago I noticed a awful noise coming from what I think is the alternator or the belt. When I start the car up in the morning it squakes for about 10 seconds then stops. However, even when the car is warmed up and I stop the noise comes back. It's only when I get the motor above 1500 rpm does it stop. At first I suspected it was the alternator itself but this problem has not affected the battery at all. I have all kinds of juice. What I think is happening is the belt itself has gone. I tried tightening it up but it made things worse. Has anybody else had this problem? Any ideas? I was hoping I could fix this problem myself. I hate the idea of having to take it in. The labour to change the belt would no doubt cost me a fortune. It's going to be a real bitch to get it out.
