Likely not. Check for damage anywhere done by the belt or pulley. Replace the pulley & belt, run and check for other pulleys that woble or are noisy. You never mentioned which pulley failed so I'm assuming it is an idler pulley and not one that is attached to a component (like water pump)

Not really. This happened to me on my Stratus. I replaced the belt and the pulley. All was good. Look for play on the alternator flywheel/pulley. Other than that, you should be fine.

On my 2003 Kia spectra my serpentine belt has broke for the fourth time I'm having no problem replacing it but I would like to know if you guys may know what is causing it to break?


You need to make sure ALL pulleys move /spin freely with no rough spots or binding. Make sure the belt tensioner has adequate tension for the belt.Inspect the belt once installed for proper alignment on all pulleys with engine running and there is no sign of belt walk off. Is there any abnormal noises coming from the belt area that would indicate a worn pulley bearing?

Roaring coming from the front end


Often this is a A/C clutch bearing, but do not overlook the stationary idler pulley bearings which your serpentine belt rides on,

The water pump and Alternator both have bearings as well as the Power steering pump.

These bearings can be checked by slipping the serpentine belt off and manually turning the pulleys, checking for roughness in the bearing.

Replaced the serpentine belt but now car won't start


A serpentine belt almost never breaks unless one thing happens---one of the accessories seizes and won't turn.Remove the belt and see which pulley won't turn.The serpentine belt is strong enough to keep the engine from cranking up(better grip on the pulleys compared to the old V-belts).I actually remember a tech 3 stalls down from me sell a customer an engine,only to find the alternator was just seized.(embarassing!)Any one accessory bearing will keep it from cranking up,and I'm sure you'll find it quickly after removing the belt.

Problems you have when pulley is goin bad or is bad


Symptoms of a bad Pulley

1. It is noisy and squeals when it is rotated which is usually a bearing failure. You need to ensure that the fault is in the pulley and not in the belt. Serpentine belts can become very noisy and often owners think a pulley has failed when in fact the serpentine belt is worn and needs replacing.

2. If you remove the serpentine belt from the pulley and rotate the pulley it may not feel firm on its bearing. If you spin it it by hand it will be noisy.

1994 dodge caravan was making a noise in the area of the serpentine belt....the belt has since broke..what noise like a gear grinding would be associated with this?


Could be bad bearings in the belt tensioner pulley, bad bearings in the water pump, bad bearings in the alternator (though that would tend to squeal unless they're really trashed) or bad bearings in the power steering pump.  Get a wrench on each one and see which one won't turn.

Serpentine belt broke on 87 ford econo van


ps...you do not have to Post another Question....just Add a Comment to this question.

"HOW TO": I professionally prefer the Serpentine Tensioner Tool.
Standard Rules to Removal the Serpentine Belt with an Automatic Tensioner:
1. Find the Tensioner(s).
2. Using a Serpentine Belt Tensioner Tool, Or Wrench OR Ratchet, Rotate/Move the Tensioner USING THE AVAILABLE NUT (located on the Tensioner Pulley rotating the Tensioner Pulley/Arm - moving it away from contact with the belt and towards the area where the belt is not in contact with the Tensioner Pulley. The Tensioner is spring loaded, and is hard to rotate/move.
3. Remove the loosened belt off one of the other more easily accessed Pulleys.
4. DO NOT quickly release the Tensioner, but gently allow the Tensioner to rest in its closed position.

Standard Rules for Installing the Serpentine Belt with an Automatic Tensioner:
a. Pick a Pulley that is most easily accessed. This will usually be on top. This will be the last Pulley that the belt will go on.
b. Using the Diagram: Install the new Serpentine Belt on the remainder of the Pulleys....over, under, left right.
c. Using a Serpentine Belt Tensioner Tool or Wrench or Ratchet Tool: Rotate/Move the Tensioner Pulley and Arm "away" from Belt contact area on the Tensioner. This spring is pretty hard and with a new belt, it will be even harder to install. Rotate/Move this to as-close to the maximum allowed inorder to have enough slack in the belt to get it up and over the last pulley.
d. Using your other hand - Pull the Belt up and over the Last remaining Pulley.
e. Before releasing the pressure on the Tensioner, visually inspect the remainder Pulleys and the Belts' Positioning on them.
