Ford F47Z-8620-E V-Belt

With the engine off, open the hood and locate the drivebelt at the front of the engine. Use a flashlight to check for separation of the rubber plies from each side of the core, a severed core, separation of the ribs from the rubber, and torn or worn ribs. Also, check for fraying and glazing, which gives the belt a shiny appearance. Cracks in the rib side of V-ribbed belts are acceptable, as are small chunks missing from the ribs. If chunks bigger than 1/2-inch (13 mm) are missing from two adjacent ribs, or if the missing chunks cause belt noise, the belt should be replaced. Both sides of the belt should be inspected, which means you'll have to twist it to check the underside. Use your fingers to feel the belt where you can't see it. If any of the above conditions are evident, replace the belt.
