2005 Hyundai Tuscon Repair Question
What could cause the serpentine belt to squeal
make sure there isn't a glaze building on the belt from dirty pullys. Also, make sure there isn't coolant or oil getting on the belt. Since you replaced the tensioniers, they SHOULD be fine. If they are and nothing is getting on the belt, chances are one of the belt driven components is locking or going bad.
