Does sound stop when engine warmed up or continue squealing?
Do all driven part seem Ok when pulleys hand spun w/ belts off?
Are all belts exactly correct for application, not just length but width/bevel shape?
With everything assembled, do any brackets appear slightly bent/missing spacers causing pulley misalignment?
If able to create sounds w/ vehicle stationary and helper behind the wheel, try listening through a 6' piece of garden hose moving hose tip around to suspect areas.
The water pump is a good thought also if sounds are from clutch area, when was clutch last changed also don't forget pilot if you crack things open.
Best of luck and keep us posted of what you find.
