I opened my hood this morning when warming up and as I put my ear to the alternator (being careful to not get it caught in my serp. belt) I heard a subtle 'rattling' noise. It'* noticeable when standing in front of the car with the hood up, but I didn't know what it was until I listened to the alt. Then after it was warmed up and I drove to the store, I listened to it again and it was making a high 'whistling' noise this time, on and off. I'd assume the rattling is the bearings going bad (like I need another problem).

What are other people'* opinions? It may have been making this noise for a while but I never noticed it as clearly. And my DIC/ compass... had been flickering within the past week, if that has anything to do with an alternator on it'* way out the door.

I hope it'* fine. Don't want it to die in the middle of the QEW But replacing it seems easy enough to do it myself in a short time....

Mine died like two hours after it started whistling.

Don't tell me that..

Did yours die while driving? How bad was your whistling noise? Mine is very subtle. Can't hear it until I put my ear right up to it.

Hope it'* nothing... :?

mine did.......................back in july though

Not until after I could hear it while driving. It ran until I shut the car off, then it needed a jump.

Once you learn how to change belts, then you've got the most difficult part mastered for replacing the alternator.

The flickering displays =

We did smellbirds last night with a DP 200 amp. Easy easy easy. Def do it yourself bro.

I will be changing my first belt Saturday Maybe my alt. will be dead by then anyway. :?

Thanks for that techinfo article. I need to clean the dust out of the gauges anyway

How much was that alt? Well, I won't go with the 200 anyway....hopefully GMPD has a good price in case this thing blows. It'* just like some uncontrollable force is trying to keep me from the GTA meet. :(

I think it was 250? Don't quote me on that, not sure and too lazy to open another window to look at it for ya!
For the belt tensioner make sure you have a small pipe! Right Jason?
