What Is A Power Steering Belt
The power steering belt is a belt that is used to transfer power from the engine to the power steering pump. It is a critical component of the power steering system, which helps make it easier to turn the steering wheel of a vehicle. The serpentine belt is typically made of rubber and is driven by the crankshaft of the engine.
Power Steering Pump
The power steering pump is a hydraulic pump that helps the driver steer the vehicle by giving the steering mechanism more force.
For more insight into what the power steering pump is, check out our guide on what an electric power steering pump is. Additionally, we’ve looked into the symptoms of a bad power steering pump. As well as, the power steering pump replacement cost.
Functions Of The Power Steering Belt
The power steering belt is often powered by the crankshaft pulley and is usually located in front of your vehicle’s engine. Here are some of the functions of your vehicle’s serpentine belt.
- It functions as a driver for navigating the power steering liquid pump, which transmits power steering fluid throughout your vehicle’s steering system.
- The alternator that delivers electrical energy will cease functioning once the steering belt is damaged.
- Enables the easy spinning of the steering wheel.
- Boosts the mechanical efficiency of your car engine.
- Utilizes one source of energy to leverage many components.
- Steer your vehicle’s engine accessories.
Without your vehicle’s serpentine belt, the whole automobile system will stop functioning, and every potential way to operate it will prove abortive.
Also, speaking of the power steering fluid, we have an abundance of resources that might prove insightful. Previously, we discussed the power steering fluid leak, in addition to whether can you use power steering fluid as brake fluid, as well as whether can you use transmission fluid for power steering fluid.
How The Power Steering Belt Works
When your car engine is in operation, the power steering pump is run by the serpentine belt; this helps produce the hydraulic tension that is required to help with steering.
If the belt becomes worn out, it can result in difficulties with the power steering system, including a loss of steering assist or a creaking sound when rolling the steering wheel. So, it’s important to check the power steering belt often and replace it if it shows any signs of wear.
The serpentine belt is a single, long-winding rubber belt that is utilized to steer numerous accessory devices like air and water pumps, alternators, air conditioning compressors, power steering pumps, etc. in an automotive engine.
It keeps these tools operating smoothly and efficiently. Also, it transmits energy from the engine’s central pulley to the power steering pump. A serpentine belt can either be a V-belt, a drive belt, or a power steering belt.
It is a critical device in your automobile, and once it damages or cracks, you might get stuck on the side of the highway waiting for a towing van. Hence, you need to replace the serpentine belt before it cracks to avoid more repairs and unnecessary expenses down the road.
Serpentine Belt vs Timing Belt
The serpentine belt and the timing belt are two different kinds of belts. While the serpentine belt has many V-shaped trenches that emerge vertically along the belt, the timing belt has horizontal teeth designed to match the camshaft and the crankshaft. Both also perform varied functions in your automobile.
The timing belt is found within your vehicle’s engine. It maintains the camshaft and the crankshaft in synchrony, ensuring that the valves of the exhaust and engine intake open and close in conjunction with the pistons. This makes your engine operate with ease.
For more insight, do check out our many timing belt-related articles. That includes what happens when your timing belt broke while driving. Or, whether can a timing belt last 200 000 miles or more. Not to mention, the symptoms of a bad timing belt. And, the replacement cost of a new timing belt (with some pointers on when to change the timing belt).
The serpentine belt links the engine crankshaft on the exterior of the engine to all the engine attachments. It transmits energy to the engine attachments and ensures they function efficiently. The serpentine belt is found in front of your car’s engine.
Bad Serpentine Belt Symptoms
Several common symptoms are associated with a bad serpentine belt. This is what causes issues such as a bad power steering system in your 2012 Ford Fusion. Some of these symptoms include:
#1 – Creaking Engine Sounds
A torn serpentine belt can become tough and crisp and will begin to make creaking sounds that are loud from under your vehicle’s hood. The noise becomes more noticeable as soon as your engine starts or whenever the belt is carrying weight.
#2 – Debris On The Belt
When you notice grease, pebbles, or other kinds of debris on the belt, it is an indication that your belt may not be in a favorable condition and may require replacement. You can just try out some DIY methods by wiping the oily or messy parts of the belt gently and inspecting it to see if the residue has resulted in any damage.
#3 – Driving Or Turning Difficulty
Check how easily and consistently your car can turn to see if your serpentine belt is starting to wear out. If you notice that driving or turning is sometimes hard or shaky, especially at corners that require a lot of swerving, it could be a sign that your serpentine belt or power steering belt is starting to slip.
#4 – Accessory Devices Problems
If your serpentine belt starts to weaken, it affects other accessory devices in your vehicle, like the water pump, AC system, and alternator. When these vehicle accessories are affected, it can result in overheating, battery charging issues, and climate control malfunctions.
#5 – Check Engine Light Flicker
If your check engine light starts to illuminate, it may be a sign that something is going wrong with your power steering belt.
#6 – Noticeable Tears On The Belt
If you detect any obvious signs of wear, like tears or damaged trenches, then it’s an indication that your serpentine belt has developed a fault.
#7 – Warning Lights On Your Dashboard
Warning flashes on your dashboard are an early sign you may notice if your power steering belt is worn or damaged. This is because the power steering belt is what powers the alternator, and if it stops working, the warning light appears.
Hydraulic pressure warning flash or power steering warning flash are some of the warning lights you may notice if your serpentine belt is damaged.
#8 – Air Conditioner Stops Working
The power steering belt also powers the air conditioning pump, and if the belt cracks, you will start to see that your vehicle’s air conditioner will cease functioning totally. The air conditioning pump often has its own smaller power steering belt for only the air conditioning pump in several vehicle categories (not all car models, though).
So if you have a different belt for the air conditioning pump that goes wrong, every other component might function except the AC system.
Bad Power Steering Belt
If you fail to take the signs of a bad power steering belt in your car engine seriously and replace it rapidly, it can result in more damage to your automobile. For example, it can cause an unexpected failure of power assist for the steering system, leading to difficulty turning the steering wheel.
A damaged power steering belt might also prevent the water pump from dispensing coolant via the air conditioning system. This leads to overheating in the engine.
Serpentine Belt vs Drive Belt
The serpentine belt and the drive belt are easily mistaken for each other & are frequently utilized interchangeably. However, both are different belts. The serpentine belt is lanky, slim, and interwoven. The serpentine belt’s curly nature gave it the name “serpentine belt.”
The drive belt, on the other hand, is comparable to the serpentine belt because it fulfills similar duties like regulating the air and water pumps, the AC compressor, and the power steering pump. However, there are a few exceptions to what the drive belt can do (thus, affecting the drive belt replacement cost).
While the serpentine belt can transfer power between the alternator, AC compressor, power steering pump, and water pump, the drive belt merely regulates them. Also, the serpentine belt is known to last for a long time, which is why it is used in almost all types of cars.
With the flexible material it is manufactured of, you can easily take it out and have it reinstated with a new one. The drive belt, on the other hand, is made of a thicker and harder substance than the serpentine belt.
When To Replace Your Power Steering Belt
There are two main indicators to watch out for to detect if you have a cracked serpentine belt: noise coming from the engine and uneven steering. The squeaking or creaking of the engine whenever you start your vehicle or turn the wheel, may suggest it’s time for you to change your serpentine belt.
And if your vehicle’s steering becomes slightly trembly or hard, this could be a warning sign that your power steering belt is gone bad.
Power Steering Belt Replacement
Replacing your power steering belt can be a bit complicated; however, with the correct tools and a little knowledge, you can easily accomplish the job.
Here are some of the tools you will need for your serpentine belt replacement.
- Flashlight (optional)
