When you need to replace your car’s drive belt - opens in new window or tab., there’s no time to waste. The drive belt is responsible for powering main components—like the alternator and the power steering. So failure is a problem.

In this guide, we cover what to look for when shopping for a new drive belt, including durability and fit. We also discuss important equipment you may need to get the job done.

What to Consider When Buying a Drive Belt

With the drive belt - opens in new window or tab. powering the AC compressor, alternator, power steering pump, and sometimes the water pump, your most important consideration is the fit. It must be the exact length of the one that’s being replaced.

Another factor is the drive belt material. Most are made with a rubber-like material. These are perfectly fine. You can also find reinforced belts. These are meant for added durability and add strong synthetic fibers or Kevlar. Of course, reinforced ones are better, but stock-level quality gets the job done. Again, they key is buying a belt designed for your vehicle.

What are the best brands for drive belts?

Choose a well-known brand that offers a warranty.You can choose an original equipment manufacturer (OEM) belt that’s manufacturer-specific, such as ACDelco for your GM product or Mopar for your Jeep. Other automakers typically sell their own branded belts. For example, an OEM Hyundai drive belt comes branded as a genuine Hyundai part. There are other suppliers worth recommending. The following brands offer automotive parts for a wide variety of vehicles.

Continental: While this brand is most known for its tires, the company also makes durable aftermarket drive belts known to resist wear.

Dayco: Dayco makes a variety of belts that are well-built and reliable.

Dorman: Dorman is a well-known brand for automotive parts, including low-cost drive belt options for a variety of vehicles.

Gates: Regularly hailed as one of the best belt brands, Gates creates durable V-belts and serpentine belts that are durable.

Old Cars Use Different Types of Drive Belts

An engine with multiple drive belts. — Older vehicles use multiple belts known as V-belts.

This article focuses on the single drive belt, otherwise known as the accessory or serpentine belt - opens in new window or tab.. Yet, not every vehicle uses a single drive belt. Older vehicles use multiple belts known as V-belts, each designed to control a single operation. If you’re working on an older car, you have more v-belts to buy. Otherwise, it is the same kind of purchase process and repair as with a single serpentine belt.

Can you install a used drive belt?

No. You can buy a used drive belt, but you can’t know its condition or how many miles it has seen. This is a critical part of your car, and it’s wise to invest in a new belt.

How much do drive belts cost?

You don’t need to spend a lot of money to get a good drive belt. Many options are available between $20 and $100, depending on the type of vehicle you drive. Even a name-brand belt, as mentioned above, isn’t a huge outlay (considering its importance).

If you are particularly worried about cost, know that it should take less than an hour to replace the drive belt. You save on labor costs when you do the work at home.

Parts and Tools for Replacing Your Drive Belt

It’s common to replace the tensioner - opens in new window or tab. and pulleys - opens in new window or tab. with the drive belt, because they need to apply adequate pressure and tension for the belt to work correctly. As the belt fails, it stretches. That stretching wears down the pulleys and tensioners. If you put a new belt on worn tensioners, they can cause the new belt to slip, break, or become misaligned.

While you already have the belt off, replace the pulleys and tensioner at the same time.

Also, with the belt is off, you have one step behind you—so consider replacing the alternator, power steering pump, or water pump (if belt-driven). If these parts are nearing the end of their lives, now is the time to make the swap. It also works the opposite way: If you are replacing one of those parts, it’s a good time to put on a new belt.

Replacing the drive belt takes less than 30 minutes. That time estimate gets longer if you are working with a transverse engine (due to the belt location near the subframe). Transverse engines are mounted side- to- side, not front- to- back. If you’re working on a truck, it’s probably longitudinal. If you have a front- or all-wheel-drive car or crossover, it’s probably transverse.

We recommend using a long-reach wrench or specialty tool to release the tensioner pulley with some models. You may also want a belt tensioner tool kit that contains common open-end wrench fittings and square-drive ends for the replacement.
