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.
