This multi-ribbed belt transmits power from the engine crankshaft to the alternator pulley. It sits in the front accessory drive system, where its six ribs engage matching grooves on the pulleys to prevent slip under varying load. A worn belt produces a squealing sound during startup or under electrical load and can reduce alternator output, leading to battery discharge. Continental manufactures this belt to match the original profile and tension characteristics, so the alternator maintains its rated charging voltage without requiring adjustment of the tensioner position. On replacement, verify the belt routing matches the original layout and that the tensioner moves freely within its travel range.
