It’s easy to forget about your serpentine belt, especially since it’s not as flashy or high-tech as the rest of your car. But that doesn’t mean it isn’t important. In fact, if you don’t take care of your serpentine belt, you could put yourself at risk for serious damage, as well as a breakdown on the side of the road. It is best to take care of it as the serpentine belt replacement cost is always on the high side.
Serpentine belt replacement costs can be anywhere from $300 to $500. This is an estimate, so it’s important to call a mechanic and get an estimate specific to your car before you take it in.
Also, the cost of replacing a serpentine belt varies depending on what kind of car you drive and where you live, but on average, a typical replacement job costs anywhere between $100-$1000 depending on which auto repair shop performs the service.
What is a serpentine belt?
Serpentine belts, also known as “serpentine” belts or “drive belts,” are belts that connect your car’s steering, cooling, and alternator systems to the engine. The serpentine belt is wrapped around pulleys and driveshafts, so when it breaks, your car stops running.
The serpentine belt is made of rubber with a steel core. It has grooves to allow any lubricant to flow through it as well as a series of V-shaped ribs that help prevent slippage on turns. When the belt breaks, it can cause damage to other parts of your engine and even blow a head gasket.
If you notice cracks in the rubber or hear squeaking noises coming from under the hood, the chances are good that this belt needs replacement soon. You can check for these signs by looking at them closely through the underside of your hood or inside through an open door on a warm day (when possible).
Serpentine belt replacement cost
If you are replacing your serpentine belt yourself, expect to pay between $100 to $1000 for parts and labor, depending on where you live and how much work needs to be done on other parts of the engine. For the at home serpentine belt replacement, its cost depends on how far you live need to work it done.
A bad serpentine belt can cause several problems with your engine, including overheating and loss of power when accelerating. It can also lead to premature wear on other parts of the engine because they are not getting the proper lubrication they need to function properly.
So, you should never look at the money and ignore changing or replacing your serpentine belt. Failure to replace them can turn into a serious hazard and make things worse.
Serpentine belt vs timing belt
It’s easy to get confused about serpentine belt vs timing belt. But if you’re wondering about the difference between them and which one is better for your car, we’ve got you covered.
To start, let’s do a quick crash course on how cars work. Do you know that big metal engine block that sits under your hood? That’s your engine. It has pistons in it that move up and down to make the car go.
The serpentine belt runs around the outside of your engine, driving all of the accessories like power steering and air conditioning. If that belt breaks, it can cause those things to stop working, which means no power steering or AC, and that could be bad news if you’re driving somewhere hot or cold.
The timing belt is inside of your engine and helps turn the camshafts that open and close valves inside of each cylinder so fuel can enter at just the right time and be ignited by spark plugs. If this belt breaks, then none of those things will happen properly.
So, what is the Difference?
Both serpentine belts and timing belts are used to drive the pulleys on your engine, but they are two different components. While they do have some similarities, they also have some differences that make them better suited for specific engines.
Here are some of the main differences between serpentine belts and timing belts:
Serpentine Belts
- Are a continuous belt that wraps around all of the pulleys on your engine
- They Are made from rubber or plastic materials with Kevlar fibers for strength
- They Are designed to last for around 100,000 miles
Timing Belts
- Are a looped belt that attaches to the crankshaft only (sometimes called a “drive belt”)
- They Are made from leather or synthetic rubber materials with carbon fiber strands for strength
- They Are designed to last for around 60,000 miles
What does a serpentine belt do?
A serpentine belt is a belt that connects your engine’s accessory drive components. It drives items like your alternator, air conditioning compressor, and power steering pump.
If you have a car with an internal combustion engine, you probably have a serpentine belt. It’s one of the most important parts of your engine because it keeps all these parts turning at the right speeds so they can do their jobs.
It’s made up of rubber, which is soft and pliable, and so it flexes as it goes around pulleys and gears. But even though it’s flexible, it’s also strong enough to withstand high temperatures and vibrations caused by rough roads or other conditions that could damage other types of belts that are used in vehicles with internal combustion engines (ICEs).
In addition to being flexible, serpentine belts are long enough so that they don’t need much slack when they’re installed correctly.
This makes them very durable compared to other types of belts used in cars because there’s less chance for wear-and-tear due to stretching over time or excessive wear from friction between metal surfaces (which occurs when metal parts rub against each other without enough lubrication).

What happens to a car when the serpentine belt breaks?
When your serpentine belt breaks, it can be disastrous for your car.
The serpentine belt is a rubber belt that connects all of your engine’s accessories to the crankshaft pulley. It powers things like the water pump, alternator, and air conditioning compressor, so if it breaks, you’ll lose power to those items, and they won’t work anymore until you fix the belt.
You should always check your belts regularly; they’re cheap and easy to replace! If you notice that your belts are cracked or frayed or have come loose from their pulleys, then it’s time to replace them.
When your serpentine belt breaks, here’s what happens:
1.) Your engine will stop running because there’s no more power coming from the accessories that are attached to the belt.
2.) Your battery will start draining because it can’t recharge itself anymore, thanks to the lack of power from your alternator.
3.) Your cooling system won’t work as well because there isn’t any coolant being pumped through it by the water pump anymore.
Can you drive without a serpentine belt?
Yes, you can drive without a serpentine belt. The serpentine belt is the drive belt used to power your engine’s accessories, like your alternator, air conditioning compressor, and water pump. It’s a flat belt that wraps around all of these components and keeps them spinning in unison to keep your car going.
When this belt breaks, you should replace it as soon as possible because it can cause serious damage to your vehicle.
However, if you don’t have one on hand and you need to get somewhere fast, you just need to turn off unnecessary accessories like the radio or A/C, so they don’t drain power from the battery when they’re not being used.
7 Symptoms of a bad serpentine belt
If you suspect that your serpentine belt is broken or slipping off its pulleys, then take care of this right away. It is important to take care of these issues as soon as you notice them because if left unchecked, they can cause even more expensive problems down the road.
If you’re looking for the symptoms of a bad serpentine belt, you’ve come to the right place. Here are some signs that your serpentine belt is on its way out:
1. The vehicle hesitates when you accelerate
A bad serpentine belt can cause problems with the other auto parts in your vehicle. One of the symptoms is that your vehicle hesitates when you accelerate because there are some things that are not working properly with your engine. But a proper diagnostic check-up will be able to determine whether or not it is just a problem with the serpentine belt or if other auto parts need replacement.
2. The vehicle shakes while idling.
If your vehicle shakes while idling, it may be a sign of a bad serpentine belt. A bad serpentine belt can cause additional damage to other components in the engine compartment like the power steering pump, alternator, and water pump. If the belt fails completely, your vehicle will stop working without warning.
3. The engine temperature gauge goes up rapidly when the engine is cold
Serpentine belts are among the most common sources of engine problems. In fact, one of the earliest warning signs of a bad serpentine belt is rapid overheating when the car is first turned on. The engine temperature gauge goes up rapidly when the engine is cold, even though it later settles into normal operating temperature as long as you are driving.
4. There is a burning smell coming from under the hood
A burning smell coming from under the hood is often a sign that your serpentine belt needs replacing. Once the belt has been replaced, you should notice the problem disappear. Like most other parts of your engine, a bad serpentine belt can cause problems with your AC compressor, power steering pump, and alternator.
5. Loud squealing sounds when you start your car
When your serpentine belt starts squealing, it may be time to replace it. The squealing sound is caused by friction that occurs as the belt flexes when you are turning and stopping.
This can also be an indication that the belt is separating from its grooves on the pulleys inside your engine, which would be an even more serious problem.
While this may seem like a minor issue, it can actually mean serious damage to your car, especially for older cars with higher mileage or inconsistent maintenance.
6. Vibrations throughout the car when you’re driving
Vibrations throughout the car when you’re driving are a clear-cut sign that something is wrong with your serpentine belt. This part helps transfer the engine’s power to accessory systems (AC unit, power steering, etc.), which means that if it breaks, belts slipping or slipping components can cause serious issues.
7. The check engine light comes on.
The check engine light will come on in your car if the serpentine belt is broken, frayed, or slipping. The belt is responsible for driving the accessories in your engine.
It takes power from the crankshaft and distributes it to the water pump, air conditioning compressor, and alternator. A belt that has been compromised won’t provide enough power to these accessories, which can lead to big problems.
What is the average cost of replacing a serpentine belt?
The average cost of replacing a serpentine belt is $200-300. It’s important to know what kind of belt you need before you call a mechanic, as there are several types and sizes available. You should also be aware that the labor cost will vary depending on where you live and the type of vehicle you own.
How do I know if my serpentine belt is bad?
Your serpentine belt is the one that powers your engine. It’s a belt that wraps around a pulley system that looks like a snake, hence the name.
If you’re wondering whether or not it’s time for a new serpentine belt, there are some signs to look out for:
- You hear squealing when the engine starts up
- The engine runs rough, dying or stalling at stoplights
- There’s an odd smell coming from under the hood.
- Your car overheated unexpectedly
What happens if the serpentine belt breaks while driving?
If your serpentine belt breaks while you’re driving, it could cause a serious car accident. The serpentine belt is a part of your vehicle’s engine that keeps the pulleys and accessories moving properly. Without it, those parts would stop working and cause your engine to overheat or stall out.
If that happens, pull off the road as soon as possible and turn on your hazard lights so other people can see you. Then call for help from a roadside service. A professional mechanic will be able to come out and fix your vehicle as quickly as possible so that you can get back on the road again without having any accidents.
What does a worn serpentine belt sound like?
Worn serpentine belts can make a lot of noise, but the exact sound depends on how worn the belt is, whether you have a serpentine belt with a tensioner, and what kind of engine you have.
If your serpentine belt has a tensioner, it’ll be louder than if you don’t have one. If you don’t have one and just have a single belt, it’ll also be louder than if you had multiple belts.
Generally speaking, if your car sounds like an old V8 or V6 gas engine (so loud that it makes your ears ring), then it’s probably the serpentine belt.
But keep in mind that there are other things that could cause this kind of noise as the alternator or water pump could also be worn out and make noise.
Is a timing belt the same as a serpentine belt?
A timing belt is not the same as a serpentine belt. A timing belt is an engine component that drives the camshaft, crankshaft, and water pump. A serpentine belt is a rubber belt that drives several components, including the alternator, power steering pump, air conditioning compressor, and water pump.
The main difference between these two belts is in their construction. Timing belts are made of nylon or polyester; they are also reinforced with fibers. Serpentine belts are made of rubber, but they are sometimes reinforced with Kevlar or steel cords.
Serpentine belts tend to be more durable than timing belts because they don’t have any moving parts—they just stretch and compress when necessary to drive their respective parts.
Timing belts have teeth on one edge that mesh with grooves in the pulleys they drive, which makes them more likely to break or slip if they’re worn out or damaged by age or heat exposure like serpentine belts can be.
How long will a cracked serpentine belt last?
The lifespan of a cracked serpentine belt depends on several factors, such as the size of the crack and whether or not it’s been repaired.
Cracks in serpentine belts can be caused by overstretching and excessive wear. If your vehicle has a cracked serpentine belt, you should consider having it replaced immediately. A cracked serpentine belt can cause serious damage to your engine if it breaks during use.
If you have a small crack that hasn’t spread into the rubber layers yet, then the belt will likely last for another 50k miles or so before needing replacement.
However, if the crack is large enough that it has already begun to tear through one or more layers of rubber, then the belt will need to be replaced immediately and may not last as long as expected before breaking again.

How long do belts last on a car?
The average lifespan of a car’s belt is about 100,000 miles, but this varies based on the type of belt and how well it was maintained.
The most common types of belts are serpentine belts, which drive multiple accessories like the alternator and power steering pump, and V-belts, which are used to drive accessories like the water pump or air conditioning compressor.
What causes a serpentine belt to crack?
The serpentine belt (also known as a drive belt) is a rubber belt that connects the crankshaft to the camshaft. It runs around the water pump and alternator. If your serpentine belt cracks, you will probably notice a burning smell coming from your engine compartment.
There are several factors that can cause your serpentine belt to crack:
- The age of your vehicle
- The number of miles you’ve driven it
- How well you maintain it (especially how often you replace it)
- The tensioner has failed
- The water pump is leaking coolant or is low on coolant
- The pulleys have worn down
