- Bad Serpentine Belt Symptoms: Drive Belt Failure Signs.
In this video you will learn the 6 common signs of a failing/failed serpentine belt. A Drive belt, is an essential part of your vehicle's engine, can show several telltale symptoms. Here are some common signs to watch out for:
Squealing Noise: One of the most noticeable signs of a bad serpentine belt is a loud squealing noise coming from the engine, especially when the vehicle starts up or during sharp turns. This is often due to the belt slipping on the pulleys.
Visible Wear and Tear: Over time, serpentine belts can develop cracks, fraying, or even missing chunks. If you notice such physical damage on the belt, it's a clear indication that it needs replacement.
Power Loss to Vehicle Accessories: The serpentine belt drives various accessories like the alternator, power steering pump, air conditioning compressor, and sometimes the water pump. If the belt is failing, these components might not function properly, leading to issues like dimming lights, loss of power steering, or ineffective cooling.
Overheating Engine: If the serpentine belt drives the water pump, a failure could lead to poor coolant circulation, resulting in engine overheating.
Battery Warning Light: If the belt slips or breaks and fails to properly drive the alternator, the battery may not charge effectively, leading to a battery warning light on the dashboard.

Thank you, my coolant consumption is so high accompanied by those squealing sounds. I’ll have the belt replaced tomorrow
Nice and clear
Thank you!
I wish I knew this beforehand. My best broke off during driving. Car over heated slightly and stalled. Can my car still start without a belt in it? Or is it a sign the car isn’t repairable? I was planning on getting a new belt and check all the pulleys. If I replace them would it start the car???
I would think that the rubber of the belt . At some point would get too hard , not supple enough . To grip and make proper contact with the pulleys .
UPDATE - I had recently replaced my alternator , watched a UA-cam channel how to . Replaced the serpentine belt as my vehcile has 71,000 miles on it . It seems common sense to replace it each time you replace the alternator . I was able to easly twist the old one in my hands . New one of course is very stiff and unable to twist it . It expect the old one was slipping . Read to replace the serpentine belt at 50000-60000 miles
