Your car’s engine is a complex system of components working in harmony. One of the most critical players in this system is the serpentine belt. If you’re a Calgary driver, understanding this belt’s function can help you stay ahead of costly repairs and unexpected breakdowns. Let’s explore what a serpentine belt is, how it differs from other belts in your car, and when you should get it replaced—especially with expert help from Urban Lube.
What Is a Serpentine Belt?
A serpentine belt, also known as a drive belt or accessory belt, is a long, continuous rubber belt that winds through multiple engine components. It powers essential systems such as:
- Alternator
- Power steering pump
- Air conditioning compressor
- Water pump (in some vehicles)
Unlike older vehicles that used multiple belts, modern vehicles rely on just one serpentine belt—making it essential for smooth and efficient engine operation.
Types of Belts in Your Vehicle
Your vehicle may use different types of belts, depending on its age and design:
- Serpentine Belt: Powers multiple accessories with one belt
- Timing Belt (or Timing Chain): Coordinates the engine’s valves and pistons
- V-Belts: Found in older models, each powers a single accessory
Each belt has a unique function, but the serpentine belt is particularly vital because of its role in powering multiple components at once.
Serpentine Belt vs. Timing Belt
It’s common to confuse the serpentine belt with the timing belt, but they serve different purposes:
| Feature | Serpentine Belt | Timing Belt |
| Function | Drives engine accessories | Synchronizes crankshaft and camshaft |
| Location | Outside the engine block | Inside the engine block |
| Lifespan | ~90,000 to 160,000 km (varies by model) | ~100,000 to 160,000 km |
| Appearance | Ribbed, long and visible | Toothed, hidden inside engine |
While both are essential, a failure in the timing belt often causes more engine damage than a broken serpentine belt.
When Should You Replace the Serpentine Belt?
Over time, the serpentine belt wears down due to friction and heat. Here’s when to consider a replacement:
- Every 90,000 to 160,000 km, or as recommended by your vehicle’s manufacturer
- During regular maintenance or when other engine repairs are being done
- If there are visible cracks, fraying, or glazing on the belt
If you’re unsure about the condition of your serpentine belt, a professional inspection at Urban Lube Calgary can give you peace of mind.
What Are the Symptoms of a Bad Serpentine Belt?
A failing serpentine belt can lead to serious performance issues. Watch for these signs:
- Squealing or chirping noises under the hood
- Difficulty steering (loss of power steering assist)
- Overheating engine if the water pump stops working
- Battery warning light due to alternator failure
- AC not working or blowing warm air
Ignoring these symptoms can lead to expensive repairs, including damage to the alternator, water pump, and power steering system.
Can a Bad Serpentine Belt Cause the Check Engine Light?
Yes, in some cases. A failing serpentine belt can cause systems like the alternator or water pump to malfunction. When this happens, your engine’s sensors may detect irregularities and trigger the Check Engine Light. While the belt itself doesn’t directly cause the warning, the chain reaction it starts certainly can.
Can a Car Run Without a Serpentine Belt?
Technically, your car might start without the serpentine belt—but it won’t run for long.
Without it:
- Your battery will drain (alternator won’t charge)
- Power steering will fail
- Engine will overheat due to coolant system failure
- Air conditioning will stop functioning
Driving without a serpentine belt isn’t just risky—it’s dangerous. If your belt breaks on the road, pull over and call for roadside assistance immediately.
