Unlike an engine timing belt, a serpentine belt is typically found on most vehicles powered by an engine, providing constant mechanical power to keep your alternator charging the battery and A/C system blowing cold, among other essential systems. When a serpentine belt begins to fail, it can cause your engine to run poorly, and it can shred, getting caught up in the engine pulleys. Continue reading to find out more about the signs of what to look for behind your serpentine belt failures, and book your appointment for replacement at Downtown Lincoln for peace of mind.

Common Signs of a Failing Serpentine Belt
A serpentine belt is looped around the various engine pulleys that drive a variety of systems, keeping everything functioning as intended and ensuring your vehicle remains reliable. However, there are some early signs to look out for that mean it’s time to replace the serpentine belt, including the following:
- Squealing or chirping noises: The belt is slipping on the pulleys due to wear or loss of tension.
- Cracks, fraying, or glazing on the belt: Visible surface damage indicates the belt material is deteriorating.
- Power steering loss or heaviness: A failing belt may not drive the power-steering pump effectively.
- Battery warning light: The alternator may not be spinning fast enough to maintain proper charging.
- Overheating engine: The belt may no longer be driving the water pump correctly.
- Accessory malfunctions: Systems like the A/C compressor or alternator may stop working consistently when the belt is worn.
How Often Serpentine Belts Require Replacement?
A significant factor that determines whether your serpentine belt is suitable for continued use on your vehicle’s engine is its condition. However, since it’s made of rubber, engine heat and the climate you drive in can impact how long this belt lasts before it starts to show signs of wear and tear, or even worse, exhibit symptoms of a severely worn-out belt. It’s a good idea to have the serpentine belt checked during every oil change and have it replaced every 5 years or so. Consider replacing or inspecting the belt more frequently if you typically drive on unpaved roads, dirt roads, or gravel roads, as debris can accumulate on the belt and cause damage.
Serpentine Belt Replacement Service FAQs
Do all Lincoln models use a serpentine belt?
Yes, serpentine belts are used on all gasoline-powered Lincoln vehicles to power accessories and other essential systems, such as the alternator, which recharges the battery.
What’s the difference between a timing belt and a serpentine belt?
A timing belt keeps engine timing in check, maintaining constant synchronization between the exhaust and intake valves, whereas a serpentine belt provides power to systems that run off the engine, such as the alternator, among others.
How much does it cost to replace a serpentine belt?
A serpentine belt is typically inexpensive to purchase and can be replaced in an hour to two hours, depending on the vehicle’s engine type.
What are the symptoms of a bad serpentine belt?
A bad serpentine belt will usually emit a squeaking noise from under the hood. However, in more severe cases, it will cause systems not to function properly, and it’s possible to smell burning rubber if it starts to slip on the engine pulleys.
How often should the serpentine belt be replaced?
A serpentine belt should be replaced every 30,000 to 60,000 kilometres as a general rule, but it’s a good idea to also inspect the rubber belt’s condition before replacing it to look for cracking, glazing, or any other signs of wear that would indicate immediate replacement.
