When cold starting I get a screaming noise like a loose belt from the alternator/belt/pulley. Removed the A/C belt and still does it. Then also removed the alternator belt and it does not do it. Replaced with new belt still does it. Replaced alternator with a re-manufactured one and still does it. Put on a new one and it still does it. Where can this noise be coming from? There is no idler pulley, only crank pulley and the one on the alternator. Only does it once on first startup of the day. Never again until the next day.
