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.

Good Maintenance Practices - S1 B1Do not use belt dressings to stop belt slippage or noise. These are oil based and may cause belt deterioration.
Good Maintenance Practices - S1 B2Never twist a belt more than 90 degrees during inspection. This may damage the tensile cords and cause premature failure.
Good Maintenance Practices - S1 B3Replace serpentine belts every 60,000 - 100,000 miles. Check vehicle's owner's manual.
Good Maintenance Practices - S1 B4Replace V-belts after 3 to 4 years, or every 36,000 to 48,000 miles.
Good Maintenance Practices - S1 B5Use an approved tension gauge to check belt tension.
Good Maintenance Practices - S1 B6Check for proper belt tension after 500 to 1,000 miles following belt installation. Recheck often, at least twice a year or every 6,000 miles.
