I see that one belt in off the pulleys one belt is connected and room for one more belt is missing. i believe is the drive train belt. first the battery light turned on, never did see the temp gauge go up. now i think the battery light came on due to the drive train belt loosing traction or breaking? towed car, turned on car to help move for the tow truck, felt that the power steering did not work…again i think due to the drive train belt not being there. what needs to be checked or replaced, what do i order for the repair? i tried to order a repair for serpentine belt but your mechanic

The belt squeals because there is improper tension in the belt drive system. This is usually caused by a worn automatic tensioner, but other causes can include a contaminated belt (oil, belt dressing, etc.) or a belt that is too long or worn out.
Engine belts like the serpentine belt or the timing belt help time and operate different parts of the engine and hearing belt noise like a screech or squeal on startup, especially when it`s cold outside, probably means an engine belt needs replacing.
A loose or worn fan belt, also known as the serpentine belt, is usually the cause. Replacing this belt or belt pulley should eliminate the sound. Consider having the timing belt checked as well.
Your engine belts make a screech or squeal noise usually because the rubber belt is slipping on the metal pulley and just like your tires spinning on the road, this causes noise. The belt may be slipping due to improper tension or because it simply has gotten old and the surface has become glazed, cracked or brittle.
A misaligned pulley or tensioner is the most intriguing cause of the alternator belt squeaking noise. If you are getting squealing noise out of your car after a new device installation, there is a high chance that the tensioner or the idler pulley is out of its regular alignment.
Belt Noise
As these belts wear out, they can begin to squeak or squeal. They make noise because there is not enough tension on the belt, or because the pulleys are misaligned or weak. Often, simply changing the belt will make it stop squealing. The noise isn`t usually a danger, though it does sound alarming.
Check if the squeaking noise is persistent when you turn on your car, and it feels like it`s coming from the front of your vehicle (under the hood or from the engine bay). If yes, then the squeal you hear is from your serpentine belt or drive belt.
That`s why you may hear squeaks from your car occasionally. It may be due to several reasons, such as a loosened or worn-out serpentine belt, a faulty power steering system, suspension, or worn-out brake parts, which may require higher technical know-how to correct.
Hi there. A squealing noise is a common sign that the rotating parts such as your belts are slipping on their pulleys. A worn belt will make this noise due to the loss of tension and gripping ability of the belt. A simple replacement of your belt(s) will solve this issue.
Heat and friction of normal use slowly wear down the belt before it breaks. You know it`s time to have your belt inspected and replaced when the squealing noise gets louder and louder each trip you take.
It can squeak, squeal, chirp and clunk, imitating a bad engine-driven accessory or engine bearing. These noises can fool even the most experienced mechanic and lead to an expensive misdiagnosis. Squeals and chirps are definitely the two most common serpentine belt noises and usually result from different problems.
Knocking Sounds
If the timing belt tensioner is loose and the timing belt is getting stretched out because of this reason, you will continuously hear knocking or slapping noises. This happens because the loose timing belt hits several parts inside the timing belt cover.
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 tensioner pulley bearing is broken, and the car will make a harsh metal noise when accelerating. The function of the tensioner is to guide and tighten it on the timing belt or timing chain of the engine, so that it is always in the best tightening state.
If you ever hear a loud engine squeal or screeching noise when starting your car, it could be a sign of a bad serpentine belt or an alternator that is failing. A bad alternator is the most common cause of a car that squeals when starting.
High-Pitched Squealing
Belts tend to squeal or chirp when starting your car and in colder weather, and they will begin to quiet down as the engine compartment warms up. If your car`s belts continue to make noise during normal operation, you should have your car`s belts checked and replaced as necessary.

If you`ve just got a new serpentine belt installed and yet you hear the squealing noise, chances are your mechanic didn`t do a good enough job. Let your mechanic check the belt and determine if there`s a misaligned pulley or belt tensioner.
