There are V-ribs on both sides of the belt for added strength and efficiency and it is also completely crack-resistant. This Gates serpentine belt will also be ideal for various engines.

The serpentine belt is one of the most crucial car engine and hence when you replace our a worm out on, you cannot afford to make the wrong choice. But choosing one should be easy as you only need to consider the following points.
The material used to make the serpentine belt determines its performance and durability and is hence a crucial factor to consider serpentine belt.
As far as the material is concerned, most of the serpentine belts are made of ethylene propylene. It is a high-strength material and more resistant to wear and tear.
There are also serpentine belts made from Neoprene but many experts do not recommend them as they are not very durable and also do not work very well.
Next thing that you should carefully note is the size of the serpentine belt. And here you need to make sure that it will be the ideal size for your vehicle.
For this, you can either check the part number of the old serpentine belt or refer the car's manual. If you cannot locate both these things then use a string to measure the length of the belt.
Also, we suggest you to buy a belt that is one size smaller than the old one. For example, if you measured the length to be 90 inches then an 89.5-inch one will be more appropriate.
Compatibility also matters because even if the belt is the right size it might still not work for you if it is not meant for use on your particular vehicle model.
Most serpentine belt manufacturers will clearly indicate the vehicle types and models that their products are meant for, and so you should have an easy time getting something compatible.
It is always a good idea to buy your car accessories from a reputable brand and the serpentine belt is no exception.
You are more likely to get a high-quality serpentine belt if you buy from the reputable brands and most will also stand by their belts by providing a good warranty.

If you are not an experienced vehicle owner, it is not always easy to tell when you need to replace a serpentine belt.
However, this should be easy as there are certain signs and factors that should tell you that it is time to replace the serpentine belt.
An average life of a serpentine belt is between 7 to 9 years. Also most of these belts will work for a maximum of 90000 miles. Once the lifespan or mileage is attained it is time to replace the belt.
The aging belt can cause squealing and become contaminated or get misaligned. Hence, when you notice unusual noise from the serpentine belt it mean you need to replace it.
It is always advisable to inspect your vehicle frequently and when you notice obvious wear, cracks or fraying on the serpentine belt you should replace it.
