Anyone have any ideas on what could be causing a squealing/whining noise from the area around the power steering fluid reservoir and/or the serpentine belt. How do you solve this? THx

your belt isnt throwing antifreeze is it mine started squealing when my water pump whent bad and was leaking the belt ended up wet and wasnt griping on the pulleys causing the sound check for that mostly they squeal when the slip

Check the tensioner pully when they go bad they will squeal. It may be the belt needs replaced, Do not spray with silicon, on the serpentine belts it can cause the belt to slip especially on the smooth pully such as the water pump. I hope this helps.
