Sorry should have given more info. They are crusader 5.7 gas engines. I removed the belt and ran engine for a few seconds and no whine. I think this rules out transmission pump and fuel pumps. Seems to be coming from front of engine, so could be one of the pumps, raw and fresh water. Alternator? I was going to change out tensioner as a start. Has anyone had a whine from the tensioner? Belts were tight. Noise just started last trip.
Thanks all....
