A few days later suddenly, and seemingly without cause your car will make a loud squeal. Many of us have experienced it and we've all experienced the loud noise. However, it ceases within a few seconds so it's probably okay you think? No. The sound you hear is caused by your belt's tension being lost. There are a few possible causes for this to happen. The belt on your serpentine could wear out. The majority of belts last around 150,000 miles, with no maintenance, however when grease or oil gets on the belt , it could rapidly decrease its performance. Another reason is the tensioner, which is used to apply direct pressure to the belt , and eliminates the need to adjust the tension on the serpentine belt, may be faulty. Whatever the reason, you're going have to take a look under the under the hood.
To accomplish this task you'll require:
A Ratchet (with attachments of various sizes)
New serpentine belt
A new tensioner
We'll begin by examining the serpentine belt. This is an excellent way to know whether you'll need to replace the belt. If it's split in two and smashed on the corner of your air conditioner, it's evident that the belt is the cause. However, if it's still in good condition, look on the basis of wear and tear. If the belt is in a bad state and you see damages to the ribs and the inner cords. However, you might require a light and mirror to view the lesser consequences of fraying. If you notice there's no evidence that your belt's in a bad condition, it's still a good idea to look at the tensioner, but it could be an issue that is different from the pulley that is broken.
Take note of the direction your serpentine belt going across your motor. You can even sketch it out. If your belt is completely damaged or you're unmotivated like I am, there's an illustration of the serpentine belt's position within the owner's manual. It is crucial to install your belt properly. A mistake in installation can cause you to be back in the same situation within less than one month. In addition, it can harm the parts that are attached to it by causing them to move backwards. It might seem impossible however, remember that certain components run on the smooth, flat portion of the belt.
With a 3/8-inch extension ratchet, loosen and remove the tensioner. The belt will be loose and give enough slack to allow for the removal. Most cars come with enough room for you to finish this task without dismantling any other components of the engine. However, should there be other parts blocking your path, just take out enough to complete the operation in order to facilitate the reinstallation process. There's no need to take away the entire engine to change the belt. After the tensioner is removed, remove the belt off its track.
In this instance, give your belt another glance. It might not be so bad as you initially thought and in this case, you need to look for any other sources of noise. If your belt is still functioning make use of your straightedge to see how level the other parts are to it. It's possible that you need to make a few small adjustments. A bent bracket for mounting accessories can make a pulley bent and, in turn, you'll have to re-align it. The bracket is able to be bent back to its original position, but should you be replacing the belt due to a the compressor being seized, it's best to replace the washers with shims. Examine your tensioner for wear too. The pulley should be able to turn without a hitch, the spring must have a good tension as well as there should not be any friction within the pivot. It's always an ideal idea to change the tensioner every time you replace the belt. Tensioner assemblies aren't costly and neither are pulleys when you notice that they're sticking. When you're putting on your new assembly for tensioner, you should apply some thread-locking substance on the bolt in order to ensure you're getting a proper fit.

Check the areas surrounding the the belt. Look for grease or oil since they can decrease the life of the belt quickly. Repair any leaks you discover. While you're at it examine the grooves of the pulleys for dirt and oil. Clean them up and you'll significantly prolong the life of your belt.
Installation is fairly easy. You can thread the belt through the system, leaving the end in the tensioner to last. Then, hold the tensioner loose while you thread the final pulley. Make sure to tighten the tensioner assembly until you are at a an adequate tension. The tensioner will adjust itself automatically. You can test your tension by looking for marks on the sides of the unit. The edge of the belt is supposed to be between the marks for low and high on the outside of the assembly, in the event that the belt has been installed correctly.
