What Does the Serpentine Belt Do?
Although the function of this vital component of any car often remains unknown for many drivers, it does not mean that it is useless. So, what is a serpentine belt? A serpentine belt is nothing but a long snaking rubber belt with a certain amount of ribs (depends on a model) that connects the engine with some important parts of the car. In fact, you cannot ride a car normally without having a serpentine belt installed in it.
So what does this drive belt do? The main function of this car item is to transfer power from the engine to significant automotive components. If the serpentine belt in the car got overstretched, then these vital automotive components will not receive enough power from the engine. This is where the car will start working poorly producing annoying noise. That is why, if you want your car work properly and all the processes under its bonnet run smoothly, you need to ensure that your vehicle has a high-quality fan belt.
How Long Does a Serpentine Belt Last?
Obviously, everything depends on the quality of your product. In fact, every serpentine belt is meant to last long due to the use of the advanced types of rubber belts extremely reliable in their crack-resistant and heat-resistant properties. In the ideal world, your new belt is destined to work for an average of 60.000 to 100.000 miles before being replaced. At the same time, you should keep in mind that some models become manually tensioned, so they need to be adjusted properly.
Moreover, some models have a so-called self-tensioning mechanism, which results in the situation that they would wear sooner than the most lasting options in order to prevent from occasional cracking of the nearly worn-up serpentine belt. Try to check this component from time to time, especially if you notice that your car has been working with annoying noise going out from under the bonnet.
How Often to Replace Serpentine Belt?
The obvious question rises at this point: when to replace serpentine belt? Everything depends on the model of your component and its functional properties. The most obvious sign to replace your serpentine belt is when you have noticed that it got cracked. However, the time X may come sooner, for example, if it has lost its flexibility and ribs no longer provide the desired adhesion level. At this point, it is always better to remove your old serpentine belt and replace it with a new one in order to prevent potential problems during your ride.
It can be advised to look under the bonnet from time to time and check whether your serpentine belt retains its shape and it has no visible fissures or damaged zones. If you have already covered 100,000 miles with the same serpentine belt, it is high time for you to replace it and buy the same long-lasting model again as this is definitely the best serpentine belt for your car.
How to Change Serpentine Belt?
If you feel like your serpentine belt started making a squeaking noise, it’s time to think about drive belt replacement. Just follow these simple tips:
#1 Before replacing, you need to be sure how the belt is located inside your car. That’s where the serpentine belt diagram will come in handy. You can find it on the Internet or to be 100% sure how it goes for your engine, I recommend drawing belt routing schematic manually. Just take a pen and a piece of paper and make a drawing. It’s really important to have everything done accurately since this belt drives everything and your car just won’t start up if it goes wrong.
#2 To get the belt off, you need to lose the tensioner pulley first. Take the serpentine belt with your hand and carefully start moving it. After the belt starts moving, the pulley under it will be spinning. That is a tensioner pulley. It would be great to check the pulley too. Test all idler pulleys and pumps, they all have to move freely. Don’t forget to check pulleys for the water pump, alternator, smog pump, A/C compressor, and other parts.
#3 Take a special serpentine belt tool — gearwrench serpentine tool remover. Hook it up to the belt and then pull on it, but don’t push too hard. After pulling it down, the belt comes out.
#4 Take your belt diagram, remember the way your old belt was placed. Get a new one and fish it around the pulleys according to the drawing. Then push the adjusting bolt down with the help of the gearwrench. After that feel free to slide the new belt on. Make sure that it is not twisted.
#5 At the end, start the car. If your car got started, the belt is spinning right and now you know how to replace the serpentine belt.
