• Description:

  This is the genuine Ford serpentine accessory drive belt for the 2008-2011 Ford Focus with the 2.0L Duratec engine, and it also serves related 2.0L Transit Connect applications. This single multi-ribbed poly-V belt wraps the crankshaft pulley and drives the engine accessories in one continuous loop, transmitting rotation to the alternator, water pump, power steering pump, and air-conditioning compressor. Because a single belt drives everything, its condition is critical: as it ages the ribs glaze, crack, fray, or shed material, and the belt can begin to slip or run out of true. Drivers commonly report a loud squeal on cold start or when turning the wheel, chirping at idle, a battery or charging warning if the alternator slips, overheating if the water pump slows, and heavy or lost power steering assist. A belt that finally snaps immediately kills charging, cooling, and steering assist, so timely replacement is important. This OEM belt is built to the correct length, rib count, and profile for the factory routing and automatic tensioner, so it tracks cleanly and holds proper tension across the pulley path. Inspect the tensioner and idler for smooth, quiet operation while the belt is off, route the new belt exactly per the engine-bay diagram, and confirm every rib is fully seated in each pulley groove before starting the engine.
