FAQ - A1Yes, this may be indicative of an alignment issue or a failed tensioner.
FAQ - A2Yes, you may lose your power steering or stall out. Your car is not drivable when your drive belt fails.
FAQ - A3Yes, the leading causes of belt failure are improper tension and misaligned pulleys. Both these conditions cause excessive heat which leads to belt failure. Have your belts checked every 3,000 miles for belt wear, proper tension, and pulley alignment.
FAQ - A4No, when the belt backing has been torn or cracked, the belt should be replaced.
FAQ - A5No, use the belt in the way it's listed in the ACDelco belts and hoses catalog.
FAQ - A6No, remember the leading cause of belt failure is improper tension and misaligned pulleys. Improper tension will cause the belt to slip and you may notice a loss of performance from the air conditioning system as well as increased heat under the hood. High heat can lead to premature accessory failure.

If the serpentine belt becomes worn, damaged, or misaligned, it can cause friction and generate smoke.
Why is my serpentine belt squealing?
The serpentine belt can squeal due to various reasons, including tension issues, worn-out belt, or a problem with the belt's pulleys.
Is my serpentine belt too tight?
If your serpentine belt is causing issues like excessive noise or accelerated wear on the pulleys, it may indicate that the belt is too tight.
Why did my serpentine belt come off?
Serpentine belts can come off due to factors such as belt wear, improper tension, misaligned pulleys, or a faulty tensioner.
