What happens when you change the serpentine belt?
What happens when you change the serpentine belt?
Billions of rotations under constant tension of the serpentine belt will take its toll over time. The “ribs” in the pulleys get damaged so even if you change the belt, the damaged pulley will tear and shred the belt again.
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.
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).
What causes a belt to squeak over pulleys?
Squeaking is caused because the belt is slipping over the pulleys. The slipping is caused because the belt loses ability to produce enough friction between itself and the pulleys (mostly due to material fatigue).

When to replace a tensioner on a belt?
On systems equipped with an automatic tensioner, the tensioner pulley should turn freely without binding, the tensioner arm should move smoothly through its entire range of motion and there should be adequate tension. Replace the tensioner and /or pulley as required
When to replace a belt due to misalignment?
Inspect and replace all accessories / pulleys that are difficult to rotate (i.e. rough/seized bearings), or show excessive wobble / free rock Warning: Any existing misalignment condition probably caused pre-mature wear of the belt ribs on the old belt. A new belt is recommended once the accessory drive has been realigned.
Why does my serpentine belt make a squeal noise?
A serpentine belt is meant to run on various pulleys, like the idler pulley, and if any of the devices or tensioner pulley is not correctly aligned with the serpentine belt, the serpentine belt noise will occur, often in the form of a squeal.
What happens when the serpentine belt fails on an alternator?
The serpentine belt powers the alternator, and if it fails, the alternator will stop working the moment your belt wears out and breaks, or the pulley becomes damaged. This can also happen if the serpentine belt is not tightened correctly. Most cars have automatic tensioners, but these can fail, so it is better to double-check.
What is the function of an alternator pulley?
Pulleys are simply a means of transferring power. In the automotive pulley and belt system the power generated by the engine is transferred from the engine crankshaft pulley to the belt and then from the belt to the pulleys attached to various accessories such as the Alternator, Power Steering Pump,…
What kind of pulleys are used in a serpentine belt?
Both the flat (smooth) side of the belt and the ribbed side can be used to drive pulleys. This belt is commonly referred to as a serpentine belt but also goes by many other names including Multi-V belt, Poly-V belt, Poly-Ribbed belt, Micro-V belt and others.
What kind of belt does an alternator use?
Most modern vehicles use only one belt to drive all the accessory pulleys. This is a wide belt that is flat on one side and has small “V” shaped ribs on the other side. Both the flat (smooth) side of the belt and the ribbed side can be used to drive pulleys.
