Re: whistling noise
The bearings in the alternator go bad in that way sometimes. Mine whines kinda like that. Just pretend it's a supercharger, lol.

Re: whistling noise
GEt out a piece of wood ( 12 to 14" long )Push it hard against the alternator when it is running and put your ear to the other end you will hear it if it is the bearings going . they may last a year or 2 that way .

The car I just bought has the rear (alternator) bearing whining. Is the replacement bearing number known/available? It will be a fun to pretend it is a blower until the alternator, well, blows. -Mike O |
