I've had a whining sound which increases as the revs of the moror goes up. I have changed all the belts as most where pretty worn, but to my suppise when I started the car up, the noise was still there, I pout a new alternator in back in Feb this year. I've notices, if I spray crc or the like where the belts make contact with the pullies it seems to quiten it down, when the old belts where on it would be quite for that drive, then after sitting for the night it would be the same next morning, The tensioner pully for the AC seemed fine. Any suggestion and cures appreicated.
