Are you hearing a squealing sound from under your hood? Your belt may be slipping and needs replacing. When you need a quote for a serpentine belt replacement cost, visit Havoline® Xpress Lube of Kernersville.
Engine Belt Replacement Cost
Generally, many automobile engines have two different types of engine belts: the timing and the serpentine. It’s important to understand the distinction because the operation and costs are drastically different.
The serpentine belt powers several engine components: the AC compressor, power steering pump, and alternator. In some cars, it also powers the water pump.
Comparatively, a timing belt is responsible for synchronizing the crankshaft and camshafts. This ensures that the intake and exhaust valves open and close at precisely the right time.
Usually, the serpentine belt replacement cost runs between $150 and $250 and is relatively easy to change. Replacing this belt requires removing the old one and threading a new one onto the pulleys.
However, changing the timing belt for a car is a difficult, labor-intensive job, requiring the removal of several other parts. Expect to pay between $400 – $1,000.
What Does A Serpentine Belt Do?
Before the 1980s, an automobile had 4 belts that powered several vital components. While multiple drive belts did their job, they did so inefficiently. Moreover, using multiple belts and pulleys occupied a significant amount of space in the engine. Often, you had to remove other components to change drive belts.
In 1974, the inefficiency of this system caused one inventor, Jim Vance, to develop a single belt. Over the next decade, automakers began to incorporate this new component into their vehicles. Structurally, a serpentine belt is more efficient at transmitting power due to reduced friction.
Common Causes Of Premature Failing Of The Serpentine Belt
Usually, a serpentine belt can last between 60,000–100,000 miles. However, certain conditions can lead to it prematurely failing, requiring you to change this belt sooner:
- Fluid Leaks
Leaking engine fluids can cause the serpentine belt to slip. This can affect the proper functioning of all components attached to it. Additionally, the chemicals in engine fluids can degrade the belt, causing it to harden, soften, or crack.
- Damaged Components
Any connected component that begins to fail can create resistance and excessive friction, preventing the belt from moving freely. While some friction is necessary to drive the belt, too much accelerates wear.
- Failing Tensioner
To function properly, a serpentine belt can’t be too tight or too loose. As the tensioner begins to fail, it can’t maintain the correct pressure, leading to slipping and undue stress.
Signs Of A Failing Serpentine Belt
Typically, manufacturers construct engine belts out of EPDM, a synthetic rubber. Although this material is durable and flexible, it will degrade when consistently exposed to extreme temperatures. Moreover, petroleum-based products, like engine oil, can also shorten their lifespan.
You’ll know it’s time to change your serpentine belt if you notice one or more of these signs:
- Wear Marks
A visual inspection may indicate signs of deterioration like cracking, fraying, or shiny surfaces.
- Squealing Sounds
Fundamentally, a loose, worn, or fluid-contaminated belt can’t grip the pulleys properly. As a result, it will slip while moving, causing a high-pitched squealing.
- Poor Performance
Since the serpentine belt connects several components, you may experience any one or all of these conditions:
- Illuminated Check Engine Light
Typically, a failing serpentine belt won’t trigger a check engine light. However, some components connected to it can cause problems if they’re not working properly. For example, a slipping belt can’t power the water pump effectively. Without circulating coolant, the engine will run hot, triggering the check engine light.
FAQs About A Serpentine Belt For A Car
Is your automobile showing signs that you need to change your belt? Bring your car to the automotive experts at Xpress Lube, and we’ll inspect it for you. Below, we answer a few commonly asked questions about this component.
Why Should I Have The Belt Replaced As Soon As It Shows Signs Of Wear?
Once you begin having problems with engine belts, they can fail at any time. Not only can you become stranded somewhere, but you can also incur additional engine damage from an overheating engine.
Even if your belt is just slipping, it can affect your alternator. Without a properly functioning alternator, your car battery can’t charge.
Is It Safe To Drive With A Worn Belt?
No! It’s never safe to drive with failing engine components. In addition to the consequences we’ve already mentioned, your power steering could also stop working. Your vehicle can become extremely difficult to control, leading to an accident.
What Does A Worn Belt Look Like?
At least every 6 months or every oil change, you should inspect your engine belt. It should be free from cracks, fraying, or missing chunks. Moreover, it shouldn’t have any shiny-looking surfaces or glazing.
