I have a 2004 CTS 3.6L, i have a whining noise, I looked around and I think it may be the alternator, but I wanted to know if there is a way to find out where its actually coming from?

Re: Whinning Noise

1. Have someone else drive car while you climb under hood and sit there.
or
2. Get a stethoscope. Keep in mind that the alternator will be fairly loud as a result of brushes and commutator.
3. Check fluid level in power steering pump. Some p s pumps do whine on various cars. BG power steering additive (sold by many dealers and NAPA) is an excellent product to elim whine in Fords.)
