Product Description	ACDelco Professional, premium aftermarket V-Belts serve as replacement belts for today's most demanding engine drives. Due to thermal forces, these variable notched belts actually tighten on the drive as they get hot. This results in improved belt performance by reducing tension, decay, and noise. These premium aftermarket replacement v-belts are manufactured to meet your expectations for fit, form, and function. ⚠<b> WARNING:</b> Cancer and Reproductive Harm - www.P65Warnings.ca.gov
FAQ - Question 3	Are there steps I can take to ensure a longer automotive belt life?
Color	Black
FAQ - Question 5	Can I use the same automotive belt for multiple uses?
Good Maintenance Practices - Section 1 - Bullet 6	Check 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.
FAQ - Question 1	Could an automotive belt tear during use?
Signs of Wear & Troubleshooting - Section 1 - Bullet 5	Cracking: older neoprene belts crack as they near the end of their life cycle and often need to be replaced.
Good Maintenance Practices - Section 1 - Bullet 1	Do not use belt dressings to stop belt slippage or noise. These are oil based and may cause belt deterioration.
Signs of Wear & Troubleshooting - Section 1 - Bullet 6	Engine stops or backfires.
Material	Fiber Loaded Rubber
Signs of Wear & Troubleshooting - Section 1 - Bullet 2	Glazing: shiny spots can indicate a slipping belt that isn't properly transferring power to accessories.
Features & Benefits - Bullet 2	Has thermally active tensile cords that provide maintenance free performance when properly installed and tensioned
Signs of Wear & Troubleshooting - Section 1 - Bullet 8	Headlights dim while driving.
FAQ - Question 4	Is there a way to repair a torn automotive belt?
Features & Benefits - Bullet 1	Its fiber loaded rubber stock puts more flexibility along the length of the belt, yet gives the belt greater lateral stability in the pulley
Signs of Wear & Troubleshooting - Section 1 - Bullet 9	Loss of battery charge.
Features & Benefits - Bullet 3	Manufactured with form ground to ensure precise top width and sidewall dimensional control for proper fit in the pulley as well as a smoother, quieter running belt
Good Maintenance Practices - Section 1 - Bullet 2	Never twist a belt more than 90 degrees during inspection. This may damage the tensile cords and cause premature failure.
Top Cogged	No
FAQ - Answer 6	No, 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.
FAQ - Answer 5	No, use the belt in the way it's listed in the ACDelco belts and hoses catalog.
FAQ - Answer 4	No, when the belt backing has been torn or cracked, the belt should be replaced.
Signs of Wear & Troubleshooting - Section 1 - Bullet 3	Pilling: worn rubber can fill in grooves and cause noise, heat, vibration, and excessive wear.
Good Maintenance Practices - Section 1 - Bullet 3	Replace serpentine belts every 60,000 - 100,000 miles. Check vehicle's owner's manual.
Good Maintenance Practices - Section 1 - Bullet 4	Replace V-belts after 3 to 4 years, or every 36,000 to 48,000 miles.
Signs of Wear & Troubleshooting - Section 1 - Bullet 1	Rubber Loss: (most common belt wear) a belt wear gauge measures rubber loss, which can result in reduced power transfer from the crank to the accessories.
Signs of Wear & Troubleshooting - Section 1 - Bullet 7	The belt is producing a squealing noise.
Good Maintenance Practices - Section 1 - Bullet 5	Use an approved tension gauge to check belt tension.
FAQ - Question 6	Will a worn automotive belt affect gas mileage?
FAQ - Question 2	Will I know immediately if an automotive belt tears?
FAQ - Answer 3	Yes, 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 - Answer 1	Yes, this may be indicative of an alignment issue or a failed tensioner.
FAQ - Answer 2	Yes, you may lose your power steering or stall out. Your car is not drivable when your drive belt fails.
