What would cause a serpentine belt to keep coming off?
The serpentine belt need constant tension on the belt to keep it from coming off. If the belt alignment is not aligned then the belt may come off. The tensioner may be out of alignment and not putting enough tension on the belt. Have a mechanic check the tensioner and replace it if needed.
Does serpentine belt effect AC?
What does a serpentine belt do? Well, it won’t keep your pants up, but it does transport power to your vital automotive components. The serpentine belt is one long, snaking, winding belt that keeps your alternator, power steering pump, air conditioning and—in some cases—your water pump running smoothly and effectively.
What happens if the serpentine belt is not working?
It provides power for the air conditioning, alternator, power steering, and sometimes the cooling system water pump. The serpentine belt is a critical part of this system, and once the engine is running, it continues to operate until the vehicle is shut off. Without a properly functioning serpentine belt, the engine may not run at all.
Is the AC compressor capable of breaking the serpentine belt?
Thank David. Hi there, yes, the air conditioning compressor is capable of breaking the serpentine belt a couple of ways. If the AC compressors seizes while operating, the shock load can snap the serpentine belt. If the AC clutch bearing seizes while the AC compressor is not operating, the belt can snap then as well.
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.
When does the serpentine belt come off on a 2006 Ford Fusion?
Today is the4th time that the serpentine belt has come off on my 2006 Ford Fusion with a 4Cyl engine. Have had the valve cover gasket replaced due to excess oil on belt and the cover was leaking. Have had all the pulleys cleaned and the belt replaced twice since then. any ideas?
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.
