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.

Bad news.

If the sounds is coming out from the alternator, the bearings could be going out. If that is the problem, you'd have to buy a new one. I haven't heard of a belt squealing unless its loose, not because it is worn. But who knows?

I had a problem similar to yours on my old Accord. Except it was the water pump. Couldn't hear it when revving but it was a loud squeal-like sound during idle. I changed it and it was fixed.

It's not too difficult to change the alt. belt.
If the belt is on the outside, then take the powersteering and A/C belt off first. Then loosen the belt on the alt. and slide it off. If you feel you need more room to take off the belt, remove the passenger-side tire and wheel well skirt.
