General Belt Info
An improperly functioning Mustang serpentine belt can cause premature accessory failure and should be inspected for any signs of cracking or uneven wear regularly. Replacement recommended every 20,000 miles.
After much research I chose the Goodyear Gatorback belt due to lack of squeals others have experienced. Goodyear knows a thing or two about producing quality rubber which was a selling point as well. To help with the install I marked either a O (over) or U (under) on each pulley to help with belt routing.
