The possible causes of this include that the pulleys are not all in the same plane, the pulley on the harmonic balancer has shifted due to a break in the rubber bond, the belt tension is inadequate and/or the bearings on which the pulleys (or accessories) are mounted are worn or seized. To remedy this problem, a diagnostic is performed to figure out which parts have failed and need to be replaced. The belt will have to be removed (so all pulleys can be inspected) and replaced. Even if the existing belt can and will be reused the recommended service to request is a belt diagnostic/replacement and the responding certified mechanic will take it from there. This problem will be resolved very readily as the possible causes are limited in number.

Slipping can be the result of a loss of belt tension (or a weak automatic tensioner) or pulley misalignment. When the belt slips off the track, the friction between the belt and accessory drive pulleys causes the belt to overheat. If you hear a high pitched squealing noise, it`s probably time for a switch.
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.
One of the clearest signs that your serpentine belt may need to be replaced is wear and tear to the belt itself. The belt may appear cracked and frayed if it is ready to break. The tread on the belt may also be missing pieces or look flattened, both of which can cause the belt to slip.
If your serpentine belt is failing, you may notice performance issues with your vehicle. The vehicle may frequently overheat. Your air conditioning or power steering may fail to work or not work properly. You may notice your vehicle battery failing to recharge if the alternator is affected by a bad serpentine belt.
Sometimes the belt falls off (rather than breaking) because the pulleys and tensioner are worn, damaged, or misaligned. In that case, simply replacing the belt will not fix the problem.
There are a couple of factors influencing the answer to this question, but on average, your car should be able to run between 20-90 minutes with a broken serpentine belt. The engine will overheat faster without a functioning cooling system on a hot day, so your driving window is less.
What Does a Serpentine Belt Do? As we mentioned early, a serpentine belt delivers power to your alternator, power steering pump, and air conditioning compressor. In some cases, it also supplies power to your water pump. It`s a long, winding rubber band of sorts that is attached to your crank pulley.
Since the serpentine belt helps provide power to cool the engine, a faulty belt can cause the car engine to overheat as the water pump will not turn. As soon as the engine begins to overheat, have it inspected by a mechanic as it can cause a breakdown and cause engine damage if left overheated.
If a belt is not tensioned properly, it will ride too loose or too tight on the pulley. A belt that`s too loose on a pulley will cause slippage, which leads to heat build up from friction. This heat will damage your rubber belts and cause the belts to crack and break.
This damage interferes with the rotation of the belt causing torn belts, or the belt falling off of the engine. Without a belt, stalling and overheating of the engine become commonplace. For auditory cues, squealing noise from the engine belt can be a tell-tale sign.
The main physical difference between an idler pulley and tensioner pulley is a simple adjustable bolt! However, in terms of function and purpose, an idler pulley is responsible for guiding a belt drive in an engine or mechanical system, while a tensioner pulley is responsible for tensioning the drive belt.
The primary distinction between tensioners and idler pulleys is the presence of an adjustable bolt. Tensioners are positioned on the bolt through mounting. Idler pulleys are not mounted to an adjustable bolt.
What causes serpentine belts to break? Too much wear due to heat and friction will cause a serpentine belt to break over time. That`s why regular inspections are vital to making sure this doesn`t happen.
Another symptom of a potential problem with the drive belt tensioner is unusual belt wear. If the drive belt tensioner pulley has any sort of issue it can cause unusual and accelerated wear on the belt. A bad pulley can cause fraying on the edges of the belt, and in severe cases can even cause it to break.
If the dampener is not able to control the tensioner arm, it can cause fluctuations in tension. The belt may oscillate between too little tension and too much tension. The belt will slip and catch, causing noise and vibration.
Of the parts that will eventually need to be replaced in your vehicle, the serpentine belt is one of the most important. How long does a serpentine belt last? Being made of durable rubber, a serpentine belt can last anywhere from around 50,000-100,000 miles.
The short answer is yes, your car will start even if the serpentine belt is broken or missing. To get the car going, the battery sends power to your starter motor. The starter motor provides enough power to get your engine moving and the combustion process started.
If the serpentine belt completely fails and breaks, then your car will break down. In addition, you will notice a loss of power steering, the air conditioning will not work, and the engine will no longer be able to be cooled like it should be.
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.
A worn timing belt will affect your engine`s starting speed as it is attached to the pulleys that drive the crankshaft. Eventually, the belt can slip on the camshaft drive causing the engine cylinder to open and close at the wrong time.
Serpentine belts are much longer and wider than older V belts. Improved material quality lets belts last much longer. A narrow, deep V-belt design evolved into a wide, flat belt with teeth. Several V belts on older engines have been combined into one serpentine belt on newer engines.
A serpentine belt actually has the ability to transmit the power between your power steering pump, your alternator, air conditioning compressor and water pump, whereas your drive belt simply operates them..
Split belt cover
There`s a lot to be said about the damage that can be caused from forcing a belt onto a pulley or running your v-belts with the incorrect tension, as this is the most common cause for many types of belt damage, including cover splits.
