A Most Important Part (Serpentine Belt Replacement)

January 25, 2026

Your vehicle’s engine is an engineering work of wonder with many complex parts working in harmony to get you down the road. One of those simple but important components is called a serpentine belt. It is driven by a pulley on the engine and transfers that power to many of your engine’s most important components.  The serpentine belt may drive the alternator, water pump, power steering pump and air conditioning compressor.  

When it’s working like it should, you won’t even notice the serpentine belt.  But when it starts to fail, you may hear a squealing noise coming from under the hood as the belt starts slipping.  Heat and time take their toll on the serpentine belt, causing it to crack or even to start shredding.  When this happens, it may not drive your alternator correctly, and your battery light may come on.  If the water pump isn’t turning, your engine may overheat, causing the heat gauge to show hotter than usual.

When the serpentine belt isn’t doing its job, it’s important to get it serviced very soon.  Letting it go too long can result in many more expensive repairs to multiple parts on your vehicle, especially if the belt breaks.  

Regular vehicle maintenance is important, and an inspection of your serpentine belt should be one of those things you should have one of our technicians do periodically.  While the belts can last for years, it’s important to detect any beginning of wear earlier rather than later.  In addition to the condition of the belt, the technician can also check to make sure pulleys are aligned properly and that the belt is routed correctly.  

Your vehicle’s serpentine belt is one of those components that you won’t even notice when it’s doing its job, and maintaining it will help you avoid surprises at the worst possible time.
