Dayco 5040335 serpentine belt for the 2001-2005 Volkswagen Passat 4-cylinder 1.8L, the 2004-2005 Passat 4-cylinder 2.0L and other vehicles turns the alternator, power steering and air conditioning from the engine. One belt runs the whole accessory drive, so each engine takes just one.
Squealing, cracked or frayed ribs and a shiny, glazed surface can all mean a belt is worn. With the engine off and cool, run your eye along the ribs for those marks. A squeal can also come from a worn tensioner or pulley, so find the cause before you replace the belt.
The vehicles it fits include the 2001-2005 Volkswagen Passat 4-cylinder 1.8L and 2004-2005 Passat 4-cylinder 2.0L, the 1996-2000 Hyundai Elantra and the 1993-1997 Nissan Altima.
