Why does the serpentine belt keep coming off?
Serpentine Belt Keeps Coming Off. The most common reason is that the serpentine belt is just worn out and needs to be replaced. Another common cause is that the belt tensioner is froze / stuck and not functioning. The tensioner does exactly what it’s name says- keeps tension on the belt. Without tension the belt will come right off.
What causes glazing at the edges of a serpentine belt?
Glazing at the edges of a serpentine belt, or on its ridges or in the grooves, results from the belt slipping. It indicates that friction between the belt and the accessory drive pulley (s) created by slipping has overheated the belt. Fraying at the edge of a belt indicates pulley misalignment.
What causes a belt to come off without tension?
Another common cause is that the belt tensioner is froze / stuck and not functioning. The tensioner does exactly what it’s name says- keeps tension on the belt. Without tension the belt will come right off. This is the part that you must adjust or release the tension to install the belt.
Why does my serpentine belt make a screeching sound?
The belt slides over a motionless pulley causing extensive friction, heat and the recognizable sound. The screeching sound may also be caused by a severely worn out serpentine belt (in this case, it must be nearly pulverized).

Is the water pump driven by the serpentine belt?
Another important device driven by the serpentine belt is the water pump. This is not always the case as on a lot of cars the water pump is driven by the timing belt. You should have this in mind so you don’t falsely “accuse” the serpentine belt for overheating.
