Why does my serpentine belt need to be replaced?
Why does my serpentine belt need to be replaced?
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.
Why does my Dodge Nitro keep throwing the serpentine belt?
My dodge nitro kept throwing serpentine belt and after checking tensioner and replacing belt and idler I found there was a bolt missing in the power steering pump. Causing it to wiggle. Replaced bolt and tightened up pump, no more throwing the belt. Replaced belt replaced pulley.
Why is coolant leaking from my serpentine belt?
Coolant leaking from the weep hole means it is time for a new water pump, but it also may indicate that the water pump bearings are worn. If the water pump is leaking, check the serpentine belt for signs of fluid contamination.
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 serpentine belt to get stuck?
The main reason, in most cases, will be a stuck pulley from one of the devices (alternator, AC compressor, power steering pump etc) or a tensioner. A stuck pulley is mostly caused by a worn out bearing. The belt slides over a motionless pulley causing extensive friction, heat and the recognizable sound.
When do you need to replace serpentine belt tensioner?
If you see more, the dampening mechanism is worn and the tensioner must be replaced. If the serpentine belt tensioner arm moves more than 1/32″ while engine is running, the vibration dampener in the tensioner is worn out.

What to do if your tensioner belt is shredding?
Have a technician remove the belt and make sure all of the other components spin freely at the pulley. The technician will be able to determine if the belt is shredding due to misalignment. The repair cannot be complete without replacing the shredded belt as well. Once the drive belt starts to deteriorate, its life is shortened dramatically.
What can I do about the belt coming off problem?
What solves the belt coming off problem is the ridge or guide on the new and included pulleys. The drawback is, this feature also makes the new belt harder to install. For this reason I recommend getting a special serpentine belt tool to give you the extra leverage needed to fully disengage the tension spring.
Why does water jump over the serpentine belt?
In my opinion one design defect of the engine compartment is the underside is almost completely open. This allows water and snow to jump up inside and over the engine drive belt. The small splash shield underneath doesn’t divert the water that well. Nevertheless, a new belly pan is not part of the technical service bulletin.
What causes a serpentine belt to come off?
Belt coming off: Pulley misalignment, belt misalignment on pulley, defective tensioner, or bearing wear in tensioner, idler or driven accessories Belt noise can be hard to isolate, as the sound may seem to be coming from an accessory drive, such as the alternator or air conditioning compressor.
How do you replace a serpentine belt pulley?
Using the breaker bar or serpentine belt tool, move the tensioner arm against the spring as far as it will move, to its stop. The tensioner arm should move smoothly throughout its range of travel, with firm spring pressure and without binding. Most tensioner pulleys can be replaced independently of the tensioner itself.
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?
