Noisy Alternator, How Long Before Detonation?

1208 Views 7 Replies 6 Participants Last post by  Sniperdude
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.
They sell belt sprays at auto part stores where it will eliminate noises. I sprayed my belts with it and the noise disappeared. Be sure to read the bottle to see what type of belt it conditions.

he's talking about the pulley, not the belt
Oops, my bad. Yeah, WD-40 should shut the noise up if you spray it to the pulley.
If it were mine, I'd not use WD-40 (which is not a good lubricant), I'd use something like Tri-Flow.

FWIW.

Okay then, yeah that would work.
