And last, like any other item from Bando, this belt is wear-resistant. However, it does not fit with the Mazda car. And it has a weird smell when unboxed. 

Pros

  • High-quality and non-stretching belt

Reasons You Need To Buy a Serpentine Belt

1. Upgrade Your Engine 

Are you going to replace your gasket adhesives, head gaskets, or even spark plug? If you are, I think that you may have to replace all the components surrounding the engine. By replacing the serpentine belt, you will have a practical component in the front part of your car. 

2. Transmit Power 

Do you know why a serpentine belt is so important? It will deliver power to your engine to run other components smoothly. In this case, “other components” mean critical components like power steering pump, air conditioning unit, alternator, and water pump. 

3. Prevent Engine Failure 

Suppose your serpentine belt has symptoms like wearing or fraying, tearing, and cracking. In that case, all the automotive components will be severely affected. Your engine will be overhead, and your vehicle will stop mid-journey. Hence, you need to replace the belt before it destroys your vehicle’s engine. 

4. Best Design 

Recently, serpentine belts are among the cheapest and the most durable belts on the market. Compared with fan belts, standard belts, serpentine belts are more reliable, efficient, and compact. And the most important is it is super simple to install these belts. 

Factors to Consider When Buying the Best Serpentine Belts 

If you want to make the right investment to the best serpentine belts for your vehicle, you must check the following features: 

1. Belt’s Size 

You can usually find the parameter about the size of the belt based on the model number on the belt. It is the most effective way for you to find the best aftermarket size. And you should never choose a different size than this parameter because it could lead to severe consequences for your engine. 

However, it is not all the time that you can find the data. If your belt is too old and can’t read any model number, you can use the manual method: take the belt off and measure the belt’s length. In my experience, you should choose one size smaller than the real length to get the best fit. For example, if the measured length is 90 inches, you should buy the 89 to 89.5-inches. 

And the last way for you to find the best size for your vehicle is by carefully reading the car manual (if you still help it). 

2. Material 

If you want to find the best serpentine belts, you have to find the best material. The material of the belt will determine its durability and performance. So, the material is the critical factor to consider when buying the best serpentine belts. 

In the past, the most popular for the serpentine belt was Neoprene. However, this material often ends up with cracks after a short period. Therefore, it is not the best choice recently. 

Do pure research on the market. You may find that the most famous belt’s material now is Ethylene-Propylene-Diene-Monomer (EPDM). This material is more resistant to wear so that it could last longer than the Neoprene. 

3. Compatibility 

Your belt can still be incompatible with your car even when it has perfect size and material. And that is why you have to check out the compatibility before making a purchase. 

Luckily, it is not too complicated to find out if your car is compatible with the belt or not. Most manufacturers often clearly indicate the exact vehicle models and types for their belt. Everything you need to do is reading the description carefully to make sure that you are not wrong. 

4. Range and Durability 

Firstly, I have to say that no matter how much you pay for your belt, it will wear out after a specific time. However, the belts’ durability is not the same because of the material, engine, and the size of the belt. 

According to engineers, the average lifespan for the standard serpentine belt is about 60,000 miles. However, you can find the best serpentine belts, which could last for 100,000 miles. 

5. Other Features 

Brands 

I recommend that you buy the serpentine belts from a reputable brand because they can assure you of the belt’s quality and durability with a good warranty. Among thousands of brands on the market, I think Bando, ACDelco, and Gates are the most famous. 

Shear Resistant 

The best serpentine belts should have a shear resistant feature. It is the ability to self – resist structural failures like cracks or shears. The shear resistance is based on the material of the belt. And only premium belts have this feature. 

Choose the Rib Pattern

The rib pattern will decide the lifespan of the belt. And the best pattern is cross-cut with numerous valleys.  

FAQs 

1. How can I choose the best serpentine belts? 

You should choose the length, material, and brands. I showed clear instructions for choosing the best serpentine belts in the previous part of this article. Let’s read it carefully. 

2. How expensive is it to replace a serpentine belt? 

It will cost you about $25 to $75 to replace a serpentine belt. However, it could cost you more depending on the service’s location. You can’t replace the belt by yourself, so please choose a reputable garage. 

3. How long do the best serpentine belts last? 

As mentioned, the endless serpentine belts could last for about 60,000 miles. However, the best serpentine belts could last for 100,000 miles in the best condition. Sometimes you have to adjust the belt because they can be manually tensioned. 

4. Will a new serpentine belt improve performance? 

Yes, of course. A new belt with the excellent condition will lead all the other components to run their full capacity and improve your engine performance. 

5. How often should you replace your serpentine belt? 

The ideal time for checking the belt condition is every 50,000 to 60,000 miles. Besides, you should check the belt right away if you hear squealing from your engine.
