Serpentine Belt Guides

Serpentine Belt Buyer’s Guide

Summary:

  • The serpentine belt is a long belt that loops around a complicated system of pulleys to power the alternator, air conditioning system, power steering system, and water pump.
  • Although serpentine belts are made with high-grade, sturdy rubber, they’re still bound to wear out due to constant exposure to heat and friction.
  • The average lifespan of a serpentine belt ranges between 50,000 to 100,000 miles or about five years and up.
  • Common signs of a failing serpentine belt are physical damage, whining or squealing noises, air conditioning and power steering issues, engine overheating, and electrical systems failure.
  • If you’re buying a serpentine belt by itself, the cost would be around $10 to $80. Replacement serpentine belt kits which typically include the serpentine belt, the tensioner, and two idler pulleys, cost around $100 to $300.

Your car is made up of hundreds of complex interconnected parts. These various electrical and mechanical components work together to make your car run as it should. One of these complex components that is absolutely vital to your car is the serpentine belt.

What is a Serpentine Belt?

The serpentine belt, also called the drive belt or accessory drive belt, is a long, “endless” belt that loops across a complicated system of pulleys to power various parts of your vehicle. In most cases, the serpentine belt is responsible for providing power to the alternator, air conditioning system, power steering system, and water pump.

Since the serpentine belt performs a crucial function for several important systems in your vehicle, failure of this component will cause problems in other systems as well. When the serpentine belt fails, your engine accessories won’t spin at the right speed resulting in loss of power. This means that your electrical system will fail and your air conditioning and power steering systems will stop working. If your serpentine belt powers your water pump, the water pump will stop working as well causing your engine to overheat.

Serpentine Belt Location

The exact location of the serpentine belt depends on the engine layout of your vehicle. In general, it’s located beside the engine and can be seen easily when you pop the hood of your vehicle open. Since the belt snakes its way across a system of pulleys, it’s quite easy to recognize.

Other Types of Vehicle Belts

Older cars used to have multiple V-belts or fan belts to control various systems. These belts are now replaced by the singular serpentine belt in modern vehicles. Some cars also have timing belts. The timing belt is usually covered and looks quite different from the serpentine belt, so you don’t have to worry about confusing the two.

How Long Does a Serpentine Belt Last?

Although serpentine belts are made with high-grade, sturdy rubber, they’re still bound to wear out due to constant exposure to heat and friction. Many mechanics agree that the average lifespan of a serpentine belt ranges between 50,000 to 100,000 miles or about five years and up.

Checking if your serpentine belt needs to be replaced after 50,000 miles or five years, whichever comes first, is advisable. This is to ensure that the belt will always be in excellent working condition. If you don’t want to routinely replace it after the recommended mileage, make sure you take the necessary precautions. After 50,000 miles, it’s essential that you regularly check the serpentine belt for signs of damage. The important thing to remember is that the serpentine belt must be replaced before it fails completely.

Signs of a Failing Serpentine Belt

Knowing how to tell if a serpentine belt is bad can help you avoid unexpected belt failure. Here are some common signs of a failing serpentine belt:

Visible Physical Damage

Serpentine belts are exposed to heat and friction and are constantly stretched as well. With prolonged use, the rubber will start showing cracks, missing chunks, missing ribs, or frayed edges. Cracks and missing chunks are easy enough to recognize, and fraying usually happens on the edges of the belt.

Serpentine belts might also develop a shiny or glazed look. Glazing happens when the serpentine belt is constantly slipping from one of the pulleys. These are all signs that the belt is worn out and needs to be replaced soon.

Whining or Squealing Noises

Strange whining or squealing noises under the hood of your vehicle will alert you to a failing serpentine belt as well. This is usually caused by a serpentine belt that keeps on slipping, low pressure from the tensioner, or issues with your belt and pulleys not working correctly. When you hear whining, squealing, or chirping noises coming from the front of your car, make sure to check your serpentine belt for any issues.

Air Conditioning and Power Steering Issues

If you’re experiencing issues with your air conditioning and power steering system, it could be a result of your serpentine belt slipping. If your serpentine belt completely fails and breaks, your air conditioning and power steering system will stop functioning. This can cause serious safety issues when the belt breaks while you’re driving. It’s absolutely essential to avoid this scenario. Make sure to check your serpentine belt at once if you notice that your AC is not functioning normally or if you experience loss of power steering.

Electrical Systems Failure

Since the serpentine belt also powers the alternator, failures in your electrical system could also point to a worn-out serpentine belt.

Overheating Engine

If your car’s serpentine belt also powers the cooling system or water pump, its failure can also result in your engine overheating.

When looking for signs of damage to your serpentine belt, it’s also a good idea to check related components such as the tensioner, accessory pulleys, and idler pulleys. This will help you ensure that you’re replacing all worn-out components in one go.

Choosing a Replacement Serpentine Belt

Finding the right fit is the most important factor when choosing a replacement serpentine belt. Make sure to check your owner’s manual to find a replacement belt that directly fits your vehicle.

If you want to have a wider range of choices, consider going with an OE replacement for your serpentine belt. OE replacement car parts work the same as the original factory-issued component that you’re trying to replace.

In fact, OE replacement parts or aftermarket parts actually provide a better option compared to an OEM part. For serpentine belts, many aftermarket car parts manufacturers use high-grade materials and advanced manufacturing methods to create belts that are highly heat-resistant and last longer than the original part.

How Much Does It Cost To Replace a Serpentine Belt?

If you’re buying a serpentine belt by itself, the cost would be around $10 to $80. Replacement serpentine belt kits which typically include the serpentine belt, the tensioner, and two idler pulleys cost around $100 to $300.
