Changing a serpentine belt is relatively easy and a task that many DIY mechanics can do with the right tools. You will need to gather a few basic tools and supplies including a ratchet, belt tensioner tool, a new serpentine belt, and possibly replacement bolts or fasteners.
Once you have everything gathered, you will need to locate the serpentine belt and the tensioner, often found near the engine block. Then, you will loosen the tensioner’s bolts or fasteners so you can loosen the belt.
Slowly loosen the belt from the pullies until you can remove it completely. Next, install the new serpentine belt in place and slowly pull the tensioner tight to create some tension on the belt as you slowly move it onto the pullies.
Finally, you can adjust the tensioner bolts or fasteners in order to tighten the belt and make any necessary adjustments. Once you have done this, you should start the vehicle to make sure everything is working as expected.

Is replacing a drive belt easy?
No, replacing a drive belt is not necessarily a simple task. It can involve quite a bit of labor, depending on the type of vehicle and the location of the drive belt. In most cases, it is necessary to partially disassemble the vehicle in order to access the belt.
This may include the removal of other components such as the fan or alternator in order to gain access to the belt. Once the belt is located, it must be removed from the pulleys and tensioner mechanism.
Then the new belt is installed, followed by the reattachment of any components that were removed. Professional mechanics may find replacing drive belts to be an easy task, but for many individuals with limited mechanical experience, it can be quite a challenge.
Can I drive my car if the serpentine belt is broken?
No, you should not drive your car if the serpentine belt is broken. A serpentine belt is a critical part of your car’s engine, connecting the crankshaft to the various components that require power, such as the air conditioning, power steering and alternator.
When the serpentine belt breaks, your car may not be able to start or could suffer a number of other issues. If you try to drive your car with a broken serpentine belt, your car may overheat or the battery may drain quickly.
Additionally, components like the alternator will not have power and may become damaged. It is best to replace the serpentine belt as soon as possible to prevent further engine damage.
What happens if serpentine belt breaks while driving?
If the serpentine belt breaks while driving, the vehicle will quickly lose power and become inoperable. Depending on the part of the belt that breaks and where it falls, it can also get lodged in components beneath the hood and cause additional damage to the vehicle.
The serpentine belt is attached to many components in the engine, including the alternator, water pump, power steering pump, and air conditioner compressor; when the belt breaks, all of these components will stop working.
In some cases, if the serpentine belt breaks away from the water pump, the engine may become too hot and may even overheat, leading to additional engine damage. It’s important to have a qualified technician inspect the vehicle for additional damage that may have occurred if the serpentine belt breaks while driving.
What are the signs of a failing serpentine belt?
The signs of a failing serpentine belt can include a squealing or chirping noise when the engine is running, decreased engine performance, a hesitancy in acceleration, uneven engine idling, as well as a visible belt that is frayed, loose, or cracked.
Typically a failing belt will appear cracked and may even have pieces missing. It may also appear shiny and glazed due to heat, abrasion, and rough driving conditions. Other tell tale signs of a failing belt can include an illuminated check engine light, an overheated engine, an agonized grinding sound from the front of the engine, and the radiator not receiving coolant from the engine.
How do I know if my serpentine belt is going out?
If your serpentine belt is going out, there are some signs and symptoms you will likely experience. First and foremost, you may hear a squealing noise coming from your vehicle, particularly when you are accelerating.
The noise will be loud, low-pitched and distinct, and it will come and go, or continuously grow louder if the belt goes out.
Furthermore, it may cause the engine to overheat. Your vehicle’s water pump is usually driven by the belt, and so if the belt goes out, the cooling system will not work as effectively and the engine will overheat.
You can also check the belt for visible wear and tear, such as fraying or cracking.
Finally, if your vehicle has a serpentine belt tensioner, the tensioner may fail and need replacing. To check for this, you can use a bar to push the belt down and view the amount of tension in the belt.
If you can compress the belt relatively easily, it means the tensioner has failed.
How often should a serpentine belt be changed?
A serpentine belt should generally be replaced between 60,000 and 90,000 miles, depending on the type of vehicle. This is just a general recommendation, since some vehicles may require replace the serpentine belt more or less frequently.
To be sure, you should check the owner’s manual for your specific model and make of vehicle. It will inform you of recommended replacement intervals for the serpentine belt. Additionally, if you notice any cracks, frays, or other damage on the belt, it should be replaced immediately.
Performing regular inspections of the serpentine belt is also recommended, since it can provide valuable insight into the belt’s condition. If you notice any irregularities with the belt, such as irregular wear, or any other signs of damage, it should be replaced as soon as possible.
Ultimately, it’s important to follow the recommendation in your owner’s manual and stay up-to-date with any replacement intervals. Additionally, regularly checking the condition of the belt and replacing it if any issues are noticed can help keep your vehicle running optimally for years to come.
