Hi,

I have a noisy alternator, more of a whirring/whining sound, not a squealing sound. Took it to the dealer, they said it was in fact the alternator. The question is how long could it last. I have not had any issues with starting, and no discharge warning lights at all, and would like to get it repaired says a couple months into the new year. Is it more likely to last, or once it starts emitting noises like this - does this mean it will go shortly as opposed to say a couple of months. Any input of course would be appreciated.


Thanks,
Darren.

Try shooting the pulley with WD-40. A lot of the time noise is nothing more than a poorly lubricated pulley. My mom's power steering pump squeaked like crazy, I sprayed some lubricant in the pulley and it shut up immediately. Never heard from it since.

I don't think you're supposed to lubricate serpentine belts... Not sure, but just throwing it out there.

he's talking about the pulley, not the belt

If it were mine, I'd not use WD-40 (which is not a good lubricant), I'd use something like Tri-Flow.

FWIW.
