Cars have several peripheral devices also called accessories which allow their internal combustion engines to function properly. Some of the main accessories include a power steering pump , alternator, air conditioning compressor , and water pump. However, these devices cannot function properly without the help of a serpentine belt.
There is usually a belt tensioner or idler pulley to guide the belt as it moves. A serpentine belt, also called an accessory belt, is the main engine belt that you see when you open up the hood of your car. These belts are easily identifiable by their distinct ridges that run the length of the belt on one side.
The ridges help maintain grip when turning the accessory pulleys. Engine accessories need to get their power from somewhere, and it may surprise you to learn that that place is not the battery. As your engine runs, the spinning motion of the crankshaft is transferred to each of the accessory pulleys via the serpentine belt.
If your vehicle is supercharged , the serpentine belt also powers the supercharger. Older engines have v-belts instead of serpentine belts. These are thinner and smaller than serpentine belts and usually connect one accessory to the crankshaft. A bad serpentine belt is not something you can just put off and wait to deal with. The entire functionality of your vehicle may be compromised when your belt is worn, damaged, cracked, or snapped.
You will know when the belt is getting in bad shape because several signs will present themselves. Below are seven of the most common symptoms of a faulty serpentine belt:. A malfunctioning air conditioner can be attributed to a lot of things. Since the serpentine belt keeps the air conditioner functional, a bad serpentine belt will take that function away from it. If you turn on your air conditioner and see that it does not blow out cool air from the air vents, this could possibly be due to a bad serpentine belt.
If the front area of your vehicle makes squealing sounds, then your serpentine belt might be misaligned or slipping. Sometimes it might just take a realignment or proper tensioning of your serpentine belt to fix this problem. The serpentine belt allows the power steering system to function properly.
Power steering is what gives drivers the ability to smoothly steer their vehicle without needing to apply too much arm strength. If you have a bad serpentine belt, then it will be harder to move the steering wheel to steer your vehicle. This issue could also be caused by low power steering fluid. The serpentine belt is what activates the water pump which helps cool the engine.
This means that your engine will begin to overheat since it cannot be cooled down anymore. You will see this happening as the temperature gauge on the dashboard shows the needle moving toward the red zone. The serpentine belt is easy to access in most cars.
If you want to know if your belt is bad, simply open the hood and look at the belt for yourself. If you notice visible cracks or damage to anywhere on the belt, this means the belt is bad and needs to be replaced right away. A vehicle can often run without a working alternator for a bit of time, but not for long. If the belt is too loose to maintain grip on the alternator pulley, you may experience a similar symptom as a snapped belt.
If you start to notice a whine from the engine that changes with engine speed, you may want to have the tension of the serpentine belt double checked. A belt that is too tight puts too much load on the bearings in each of the accessory pulleys and can often cause premature failure of those components. One of the most common failure modes for water pumps is actually bearing failure, caused by a serpentine belt that was too tight.
Taxes and fees will be added onto these prices too. The ease of accessing the serpentine belt will determine how much the labor costs are. Some model vehicles have the serpentine belt easily accessible, which means the labor should take under one hour. But if the belt is in a more complicated area, it could take about 2 hours. Easy to reach belts can actually be changed at home with minimal tools.
